The invention relates to a method for the production and/or storage of a liquid (or fluid) provided for drinking consumption, to a liquid container (or fluid tank) that is provided for performing the method, and to a use thereof in the method.
Methods and liquid containers for producing and/or storing liquids (or fluids) provided for drinking consumption, especially alcohol-containing beverages, such as beer, wine, fruit wine, whisky, schnapps, fermented beverages, such as for example Bionade® or Kombutcha™, mixed beverages, such as juice spritzer or beers that have been modified tastefully using additional flavouring substances, are known. Known liquid containers, such as barrels, are typically made of one of the following substances resp. raw materials: wood, steel (especially stainless steel), plastics or concrete. In a traditional method for producing wine, also amphoras made of burned clay (for example natural coloured earthenware) resp. stoneware are used. Bionade is a registered trademark of Bionade GmbH of Ostheim/Rhon, 97645, Germany.
In the production of alcohol-containing beverages, a yeast resp. a yeast culture is mixed into a sugar-containing liquid, such as grape juice or fruit juice, containing fructose and being provided in a liquid container, and thereby the fermentation of the grape juice or fruit juice to grape wine (wine) or fruit wine is initiated. In the fermentation, the fructose is converted partially to alcohol, in a majority to ethanol, in an exothermic reaction in which heat is generated. Depending on the holding capacity of the liquid container and the material, from which it is made, it may be necessary to discharge the emerging heat by means of an additional external cooling system, in which a flowing cooling liquid, such as for example water, is brought in contact with a wall of the container. This holds often particularly for liquid containers that are made of plastics, so as to ensure that the plastics does not macerate under the influence of the heat.
The sugar (or fructose)-containing liquid, such as the grape or fruit juice, may also contain an acid, such as fruit acid. Therefore, the material, of which the liquid container is made, must be chosen or machined such that its surface that comes in contact with the liquid is acid-resistant. In this respect it is disadvantageous e.g. in the production of wine in barrels made of concrete, such as they are increasingly used e.g. in France, that concrete contains chalk (or calcium carbonate), a part of which dissolves partially under the influence of the fruit acid, migrates partially into the liquid, another part of which deposits on the inner wall surface of the concrete barrel. Therefore, concrete barrels are cleaned with citric acid before filling in the grape juice in order to remove the precipitated chalk residues.
For barrels made of wood, which are traditionally used in the production and storage of wine, it is disadvantageous on one hand side, that the barrels either have to be replaced after about five to seven cycles of wine production, because the inner surface of the wood has been affected, or have to be toasted (subjected to a heat treatment) in order to make the surface again suitable for the production process and/or to regenerate them. On the other hand side, the conservation of wooden barrels that are not filled with wine is problematic and requires additional measures, such as the enrichment of the air contained in the barrel with sulphur (so-called dry conservation) or the filling in of sulphur water into the barrel (so-called wet conservation).
Adepts and/or wine growers know that in the production of wine in barrels made of stainless steel, it is difficult to produce “great” wines, because among the materials (wood, stainless steel, plastics, concrete) that are common to date for manufacturing the barrels, stainless steel is the most neutral and due to the relatively smooth inner surface, only little gas exchange can take place with the filled in liquid (e.g. grape juice).
In view of the disadvantages mentioned above of the known materials for manufacturing of liquid containers or fluid tanks, such as barrels, as well as in the methods for the production and/or storage of liquids (beverages) provided for drinking consumption, especially of wine, the present invention aims at avoiding or at least reducing the known disadvantages.
In particular, there may be need to provide a method and a liquid container (or fluid tank) for producing and/or storing liquids (or fluids), especially alcohol-containing liquids, provided for drinking consumption, wherein the container is largely unlimitedly reusable and easily conservable and has a rough surface structure on its inner wall, which enables, in the method, an intensive gas exchange with the liquid to be produced and a more complete chemical conversion with only limited supply of additives that initiate and/or promote the conversion.
The present invention provides for a method for the production and/or storage of a liquid provided for drinking consumption or of a pre-product for such a liquid; a use of a liquid container in said method, and a liquid container for performing said method, according to the independent claims.
According to a first aspect of the invention, there is provided a method for the production and/or storage of a liquid provided for drinking consumption or of a pre-product for such a liquid, the method comprising the following steps:
(i) providing a liquid container, which is for producing and/or storing of liquids to be provided for drinking consumption, which comprises a container that is open on one side and a container wall having an inner wall surface, wherein the inner wall surface is formed at least partially as a surface of a solid natural stone;
(ii) cooling down at least a partial section of the liquid container with respect to the temperature of the surrounding air atmosphere;
(iii) filling in of a liquid into the liquid container that has been cooled down according to step (ii); and
(iv) initiating a step of a chemical and/or biochemical conversion of the liquid that has been filled in, such as a fermentation or a conversion of sugar to alcohol, for generating the liquid or a pre-product, wherein during the conversion no further measure (or process) for cooling the liquid container and/or the liquid residing in the liquid container is taken (or performed).
The method according to the first aspect of the invention makes use of the relatively high heat capacity (or cooling capacity) of the natural stone material, which leads to the advantage, that additional measures for an additional cooling, such as an external cooling with cooling water, can be dispensed with. The cooling down may be achieved automatically in the context (or course) of a temperature equilibration in a room (or environment) that is blocked from sunlight and heat irradiation. In particular the room may be at least partially situated under the surface of the earth, such as is the case for a wine cellar. The liquid may be an alcohol-containing liquid, such as wine, fruit wine, or another beverage that can be made from the juice of grapes or fruits, or schnapps, whisky, beer, or a mixed beverage.
According to a second aspect of the invention, a liquid container (or fluid tank), which is for producing and/or storing of liquids to be provided for drinking consumption, which comprises a container that is open on one side and a container wall having an inner wall surface, wherein the inner wall surface is formed at least partially as a surface of a solid natural stone, finds utilization in a method according to the first aspect of the invention. Thereby, the liquid may be an alcohol-containing liquid, such as wine, fruit wine, or another beverage that can be produced from the juice of grapes or fruits, or schnapps, whisky, beer, or a mixed beverage of these.
The usage according to the second aspect of the invention makes use of, on one hand, the advantageous surface characteristic (roughness) of the natural stone material as the material of the inner wall surface, which is beneficial for the chemical conversion and for an active (or agile) gas exchange with the liquid to be produced, and, on the other hand, makes further use of the relatively high heat capacity (or cooling capacity) of natural stone, which enables that additional measures for a further cooling, such as an external cooling with cooling water, can be dispensed with.
According to a third aspect of the invention, there is provided a liquid container (or fluid tank) for producing and/or storing of a liquid (or fluid), particularly an alcohol-containing liquids, provided for drinking consumption. The liquid container comprises a container that is open on one, especially the upper, side and that comprises a container wall having an inner wall surface, wherein the inner wall surface is formed at least partially, especially substantially entirely, as a surface of a solid (or massive) natural stone rock (or rock). Furthermore, the liquid container is being used in a method according to the first aspect of the invention. In particular, in the production (fermentation) of wine it has been noticed, that a surface consisting of a natural stone exhibits a natural roughness having a certain degree of roughness, which enables an intensive gas exchange with the liquid to be produced and a more complete chemical conversion with only a limited supply of additives promoting this conversion, and which, in the production of wine, enables the making of particularly fruity wines. At the same time, a surface made of natural stone is resistant in respect of a plurality of chemical substances, including fruit acids, such that a liquid container formed according to the invention is substantially unlimitedly reusable.
For implementing the invention, in one embodiment, there is provided a method for manufacturing of a liquid container (or fluid tank) for producing and/or storing of liquids (or fluids), particularly alcohol-containing liquids, provided for drinking consumption. Thereby, an inner wall surface of the liquid container is at least partially, in particular substantially entirely, formed as a surface of a solid (or massive) natural stone (or rock). The method comprises the following steps:
(a) providing a block consisting of a solid natural stone, and
(b) by means of a first hollow drill core drillbit having a first outer diameter, in the block, drilling out of a first substantially cylinder-shaped first inner wall surface having a first inner diameter, which corresponds nominally to the first outer diameter of the hollow drill core drillbit, wherein the first inner wall surface is provided as an inner wall surface of a first sheath section of a first liquid container, either directly or, if applicable, after performing a surface conditioning step.
An advantage of the afore-mentioned manufacturing method is that a sheath section usable for a liquid container according to the invention is manufactured in only one processing step, namely the drilling out by means of a hollow drill core drillbit. A further advantage of this method is, that in step (b) there is produced a substantially cylinder-shaped drill core of solid natural stone, out of which a further, in this case cylinder-wall-shaped sheath section for a second liquid container according to the invention can be produced in one further processing step of drilling by means of a second hollow drill core drillbit having a second outer diameter that is smaller than the first outer diameter of the first hollow drill core drillbit, in a material saving manner.
In the afore-mentioned manufacturing method, in step (b), a substantially cylinder-shaped drill core of solid natural stone having a first outer diameter is produced, wherein the first outer diameter corresponds nominally to an inner diameter of the first hollow drill core drillbit. The manufacturing method may further comprise the following step:
(d) in the substantially cylinder-shaped drill core of solid natural stone obtained in step (b), by means of a second hollow drill core drillbit having a second outer diameter, that is smaller than the first outer diameter by a predetermined value, and coaxially to the boring performed in step (b), drilling out of a substantially cylinder-shaped second inner wall surface having a second inner diameter, so that a cylinder sheath consisting of solid natural stone arises, which can be used as a sheath section of a second liquid container and the second inner wall surface of which is provided for usage as an inner wall surface of the sheath section of the second liquid container, either directly or, if applicable, after performing a surface conditioning step. In this way, a further, here cylinder-shaped, sheath section for a second liquid container according to the invention can be produced in a material and effort saving manner.
For implementing the invention, in a further embodiment, there is provided a method for the manufacture of a liquid container (or fluid tank) for the producing and/or storing of a liquid (fluid), particularly an alcohol-containing liquid, provided for drinking consumption. Thereby, an inner wall surface of a liquid container is formed at least partially, particularly substantially entirely, as a surface of a solid natural stone. The method comprises the following steps:
(A) providing a block consisting of a solid natural stone, which block is formed substantially plate-shapedly at least in a partial section thereof and has two plate surfaces arranged substantially parallel to each other,
(B) from (or out of) the plate-shaped partial section, cutting out at least two longitudinal sections, each of which have two longitudinal side faces, wherein the longitudinal side faces, with respect to one of the plate surfaces, either form a right angle or form an acute angle and are tilted with respect to the one of the plate surfaces, in order to enable that the at least two longitudinal sections can be arranged in a mitredly adjoining manner, and
(C) arranging three or more longitudinal sections that have been obtained from the steps (A) and (B), to (or in the form of) a hollow body, so that plate surfaces of the longitudinal sections that are arranged on an internal side of the hollow body are provided for usage as an inner wall surface of a sheath section of the liquid container.
An advantage of the afore-mentioned further manufacturing method is that it starts from a plate-shaped block of natural stone, which must have substantially only the desired thickness of the longitudinal sections of the sheath section, whereas as a starting object for the method according to the second aspect of the invention, a block of natural stone is required, that must have a thickness, which corresponds at least to the diameter of the sheath section of the liquid container. Such plate-shaped blocks of natural stone can be found in nature more oftenly, and/or can be transported more easily from a stone query to a processing site.
For implementing the invention, in a still further embodiment, there is provided a method for the manufacturing of a liquid container (or fluid tank) or of a sheath section for a container of the liquid container (or fluid tank) for producing and/or storing liquids (or fluids), particularly alcohol-containing liquids, provided for drinking consumption. Thereby, an inner wall surface of the sheath section or of the container is formed at least partially, particularly substantially entirely, as a surface of a solid natural stone. The method comprises the following steps:
(1) providing a block comprising a substantially cylinder-shaped sheath inner wall surface or comprising a bottom inner surface and a substantially cylinder-shaped sheath inner wall surface, as a bearing layer of the sheath section or of the container, and
(2) lining the sheath inner wall surface or the bottom inner surface and the sheath inner wall surface substantially area-widely with plate-shaped covering layer segments, such as tiles, which have been manufactured from a solid natural stone, to manufacture (or thereby obtain) the sheath section or the tank.
In the liquid container according to the third aspect of the invention, at least a portion of the inner wall surface (which is made from a natural stone) may have been generated by means of cleaving or drilling or sawing of the natural stone or as a result of a treatment of the natural stone with a sandblast and consequently may have had a first roughness. The said at least portion of the inner wall surface may subsequently have been subjected to a surface conditioning treatment that may have resulted in that the roughness of the conditioned inner wall surface has been increased with respect to the first roughness that has been generated by means of cleaving or drilling or sawing or as the result of the treatment with a sandblast.
In the liquid container according to the third aspect of the invention, the inner wall surface (insofar as it has been made of massive natural stone) may comprise a surface that may be bush hammered, chiseled, pointed and/or flame-chipped by means of performing an according surface conditioning step. The natural stone may be granite or basalt, and especially may not be a high-lime natural stone, such as marble.
The liquid container (or fluid tank) may comprise a lid (or cap) for covering the open side of the container. Thereby, the lid may have a lid surface (or cap surface) provided as a lid section (or cap section) of the inner wall surface of the liquid container, which is substantially entirely formed as a surface of a solid natural stone. The provision of a lid prohibits an unwanted intrusion respectively falling in of foreign matter into the liquid to be produced. When the inner wall surface of the lid is also formed of natural stone, the fluid tank can be filled up to its upper edge, and thus, its filling capacity can be employed to the full extent, whereby the liquid surface may also come in contact with the natural stone material at the inner wall surface of the lid.
The container wall of the container may comprise a bottom section and a sheath section. Thereby, the sheath section can be subdivided in a circumference direction and/or in a, e.g. axial, direction pointing to the open side of the container, in at least two adjoining sheath segments. Thereby, the sheath section may be subdivided in a direction pointing to its open side in at least two sheath segments. Alternatively or in addition, the sheath segment can be subdivided in a circumference direction in at least two, preferably four, six or eight, sheath segments. The subdivision of the sheath section into sheath segments enables that a container with a large filling capacity can be manufactured easily from plural segments, without the requirement of having available a block of natural stone having a size, that is sufficient to manufacture therefrom a one-piece container respectively a one-piece sheath section of a container.
In an embodiment, the container wall may comprise a bearing layer and a covering layer arranged at an inner side of the bearing layer. Thereby, the covering layer may be connected with the bearing layer, in particular in an area-wide manner. Thereby, the covering layer may be formed at least partially, preferably substantially entirely, e.g. as a mono block, as a surface of a solid natural stone. If it is not formed as a mono block of a solid natural stone, the covering layer of the container wall can be subdivided in a circumference direction and/or in a, e.g. axial, direction pointing to the open side of the container, into at least two adjoining covering layer segments. This embodiment is saving (natural rock) material, because only the covering layer is made of natural stone, whereas the bearing layer can be made of another material. The bearing layer can be formed of concrete or of a castable and/or mouldable, curable artificial stone (or reconstituted stone). Such a choice of the material of the bearing layer leads to a relatively high heat capacity (cooling capacity) also in the bearing layer, that is comparable to the heat capacity of natural stone, without the requirement of having available the (relatively expensive) natural stone.
The liquid container may comprise a lid (or cap) for covering the open side of the container, wherein the lid comprises a lid bearing layer and a lid covering layer arranged on an inner side of the lid bearing layer. Thereby, the lid covering layer may be connected, especially two-dimensionally connected with the lid bearing layer. Thereby, the lid covering layer may be made substantially entirely, particularly as a mono block, from a solid natural stone. This embodiment is saving material, because only the lid covering layer is made of natural stone, while the lid bearing layer may be made from another material. The lid bearing layer may be formed of concrete or of a mouldable and/or shapable, curable artificial stone (or reconstituted stone). As is the case for the container wall, this choice of materials leads to a relatively high heat capacity (cooling capacity) also in the lid bearing layer, which is comparable to the heat capacity of natural stone, without the (relatively expensive) natural stone being required.
The container wall of the container may comprise a bottom section and a sheath section. Thereby, the sheath section may be made substantially entirely, especially as a mono block, from a solid natural stone. Thereby, the sheath section may be substantially cylinder-shaped. The bottom section may be substantially plate-shaped and may be made substantially entirely, especially as a mono block, from a solid natural stone. In this way, the whole container wall may be made from a solid natural stone. Such an embodiment conveys a natural, valuable (or precious) impression, in particular for a liquid container that is shown to the public. In addition, a liquid container according to this embodiment conveys a relatively high heat capacity (cooling capacity) of the entire container.
Alternatively or in addition, the container wall of the container may be made substantially entirely, especially as a mono block, from a solid natural stone. This embodiment conveys a particularly valuable (or precious) ethnic impression, especially for a liquid container that is shown to the public.
The liquid container may comprise a lid, that is substantially entirely, especially as a mono block, made from a solid natural stone. Also, this embodiment conveys a natural, valuable impression of the liquid container, especially in cases where it is exhibited in the public. In addition, a relatively high heat capacity (cooling capacity) of the lid is achieved.
The liquid container may comprise a substantially cylinder-shaped sheath section that is made substantially entirely from a solid natural stone. This liquid container may further comprise a substantially plate-shaped bottom section that is made substantially entirely from a solid natural stone. Preferably, this liquid container may further comprise a substantially plate-shaped lid, which is also made substantially entirely from a solid natural stone. This embodiment conveys a particularly valuable, ethnic impression of the liquid container, in particular in cases where this is exhibited in the public. In addition, a relatively high heat capacity (cooling capacity) of the entire liquid container is achieved.
The liquid container may comprise a bottom section and a sheath section. Thereby, a closable and openable first liquid outlet (or liquid port) may be provided in the sheath section at a predetermined distance to a, especially bottom-sided, end of the sheath section. The first liquid outlet, which is also called clear liquid outlet in case of wine barrels, enables to withdraw liquid that has been produced entirely (or finished), whereby a possible bottom deposit residue in the barrel, which residue would cause a cloudiness of the withdrawn fluid, can remain in the liquid container. In addition, it may be provided that the bottom section comprises a closable and openable second liquid outlet (or liquid port). The second liquid outlet may be located in the vicinity of or at a deepest spot of the bottom section in operation of the liquid container. The second liquid outlet serves for draining a possible bottom deposit residual of (or in) the liquid produced in the container, and also, after a cleaning operation, for a complete draining of a cleaning liquid (or cleaning agent).
In the liquid container, the inner wall surface may be rougher than a surface that is obtained from a treatment with a sandblast. In particular, the inner wall surface may comprise a surface that is obtained from performing a surface conditioning step yielding a bush hammered, chiseled, pointed or flame-chipped surface. It turns out that it is advantageous to just not smooth, grind or polish the inner wall surface of natural stone, but to leave it with its natural roughness, such as it arises during the splitting (or cleaving) of the natural stone, or with the roughness that arises during the drilling or the sawing of the natural stone. Rather, on the contrary, it is advantageous to form (or condition) the generated inner wall surface additionally rougher in the surface conditioning step.
A skilled person, here a stone dresser, knows, that during the so-called bush hammering one knocks onto the natural stone surface with a hammer-like tool, such that individual stone platelets (or stone shivers) chip off and so that there arises a rougher surface with irregularities in evenness in the (dimensional) order of one or more centimetres. During the so-called chiseling, one knocks on the natural stone surface with a special tool that is provided with a tool head, wherein the tool head has, on its knocking side, a plurality of protrusions that cause a spalling off of stone platelets (or chips) or of stone shivers. During the so-called pointing, one knocks on the natural stone surface with a special tool that is provided with a knocking tip (or point), so as to cause the spalling off of stone platelets (or stone shivers). During the so-called flame-chipping, the surface is treated with a hot fire flame, generated for example using a thermo-burner (or flame cutter), such that stone particles, stone platelets (or chips) or stone shivers spall off (or chip off) the surface due to the heat-generated thermo-mechanical tension. The increase of the roughness can promote an intensification of the gas exchange with the liquid and also promote a chemical conversion.
A bottom section may be made of a solid natural stone and may have a thickness of more than 10 cm, preferably more than 12 cm and more preferred more than 15 cm. Such a choice of the thickness of the bottom plate is advantageous for achieving a high heat capacity (cooling capacity) due to the bottom plate (or bottom section).
A sheath section may be made of a solid natural stone and may have a thickness of more than 8 cm, preferably more than 10 cm, more preferably more than 12 cm and even more preferred more than 15 cm. Such a choice of the thickness of the sheath section is advantageous for achieving a high heat capacity (cooling capacity) due to the sheath section.
The natural stone may be a granite, including for example paragneiss, orthogneiss or syenite, or it may be basalt. In any case, the natural stone is not a high-lime natural stone, such as marble. This choice of material effects that the natural stone is particularly resistant to liquids containing acid (also fruit acid).
The method that is provided for implementing the invention, in said one embodiment, may further comprise the following step:
(c) providing a bottom section consisting of solid natural stone comprising a substantially plane surface, that is provided, directly or, if applicable, after performing a surface conditioning step, as a bottom section of the inner wall surface of the first liquid container.
Preferably, there is also provided a lid section made of a solid natural stone and having a substantially plane surface, that is provided, directly or, if applicable, after performing a surface conditioning step, as a lid section of the inner wall surface of the liquid container. In this way, a liquid container is obtained, that is substantially entirely made of natural stone, which conveys a valuable impression and is advantageous in respect of the heat capacity (cooling capacity) of the container wall of the liquid container.
The afore-mentioned method may further comprise the following step:
(e) in the substantially cylinder-shaped drill core of solid natural stone that has been obtained in step (d), by means of a third hollow drill core drillbit having a third outer diameter, that is smaller than the second outer diameter by a predetermined value, and coaxially to the borings performed in the steps (b) and (d), drilling out of a substantially cylinder-shaped third inner wall surface having a third inner diameter, such that a cylinder sheath of solid natural stone arises, which sheath is usable as a sheath section of a third liquid container, wherein the third inner wall surface of the cylinder sheath material is provided as an inner wall surface of the sheath section of the third liquid container, either directly or, if applicable, after the performing of a surface conditioning step. In this way, a still further, here cylinder-wall-shaped, sheath section for a third liquid container according to the invention can be manufactured in a material and effort saving manner.
The method that is provided for implementing the invention, in said further embodiment, may further comprise the following step:
(D) embedding (or encapsulating) or overmoulding (or injection moulding around) the hollow body obtained in step (C) with concrete or with a castable and/or mouldable, curable artificial stone (or reconstituted stone), and letting cure (or harden) the concrete or artificial stone, such that an outer sheath surface of the hollow body obtained in step (C) is covered substantially entirely with cured concrete or with cured artificial stone, in order to manufacture the sheath section. By the embedding of the hollow body obtained in step (C), i.e. obtained from longitudinal sections, in, or by overmoulding it with, concrete or with a curable artificial stone, a bearing layer is manufactured, which supports (or carries) the longitudinal sections and reinforces (or stabilizes) the entire container.
The afore-mentioned method may still further comprise the following step:
(E) providing a bottom section formed as a bottom plate, of which at least a side provided as the inner wall surface is substantially entirely formed as a surface of a solid natural stone, and
(F) connecting the bottom section with an end section of the hollow body obtained in step (C) or in step (D) in a fluid-tight manner, such that a container arises, which is open at the other (or opposite) end section of the hollow body.
In this way, a container is manufactured, that consists substantially entirely of solid natural stone, which conveys a valuable, ethnic impression and which is advantageous in respect of obtaining a high heat capacity (cooling capacity) of the container wall.
The method that is provided for implementing the invention, according to said still further embodiment, may still further comprise the following step:
(G) providing a lid (or cap), of which at least a side conceived as an inner wall surface is substantially entirely formed as a surface of a solid natural stone, and
(H) connecting the lid (or cap) with the open end section of the hollow body obtained in step (C) or in step (D) in a releasable and fluid-tight manner, such that a liquid container arises, that can be opened at the other (or opposite) end section of the hollow body by means of a lid, can be opened and can be re-closed.
In this way, a container with a lid is manufactured, which consists substantially entirely of solid natural stone, and which has the same or even amplified advantages as compared with the container resulting from the steps (E) and (F).
In the method that is provided for implementing the invention, in said one embodiment and in said further embodiment, i.e. in the first and the second one of the mentioned manufacturing methods, the surface of the natural stone that is conceived as the inner wall surface can be subjected to a surface treatment that increases the roughness of the surface and/or the specific surface of the surface. The surface treatment may comprise, in particular, a bush hammering, a chiseling or a pointing. As has already been mentioned, bush hammering, chiseling or pointing are surface conditioning techniques known to a skilled person, here a stone dresser, which serve to increase the roughness of the surface. The increase of the roughness can cause an intensification of the gas exchange with the liquid and can promote a chemical conversion.
In the method that is provided for implementing the invention, in said still further embodiment, i.e. in the third one of the mentioned manufacturing methods, the block may be manufactured of concrete or of a cured artificial stone (or reconstituted stone). In addition, a sheath section for a container can be manufactured by means of the method, wherein the block is provided substantially tubular-shaped. For example, a tube section for a wastewater conduit can be provided as such a tubular-shaped block.
In the method according to the first aspect of the invention, in the step (ii), the cooling down may occur to (or into) the temperature range of from 6° C. to 12° C., preferably to the temperature range of from 8° C. to 10° C. The temperatures mentioned herein can be met in environments (or rooms) that are blocked from sunlight and heat irradiation and may eventually partially be situated under the surface of the earth, such as is the case in wine cellars, so that the cooling down of at least the partial section of the liquid container is achieved automatically in the context (or course) of a temperature equilibration in the mentioned temperature range.
In the method according to the first aspect of the invention, the liquid container may comprise a sheath section and a bottom section, and the cooling down may comprise a cooling down of at least a partial section of the sheath section and the bottom section. In this method, the liquid container may further comprise a lid, and the cooling down may comprise a cooling down of at least a partial section of the lid.
The method according to the first aspect of the invention may further comprise the following step:
(v) in the fluid tank (or liquid container), with the pre-product obtained in step (iv), initiating, performing and/or awaiting of further processing and/or conditioning steps, such as a maturing process, for producing the liquid to be provided for drinking consumption.
Further processing steps may comprise the admixing of further substances (or agents) for a purposeful setting of properties of the liquid that has been produced (or is to be produced) and/or mixing with other liquids for producing mixed beverages. In this way, a variety of liquids can be produced using the method according to the invention.

With reference to the
A liquid container 10, such as it has been described hereinbefore, may be used in a method for producing and/or storing of liquids to be provided for drinking consumption. The basic requirements for such a container 12 comprise that the container 12 is open on one side, that it comprises a container wall 14 having an inner wall surface 16, and that the inner wall surface 16 is formed at least partially as a surface of a solid natural stone 18.
According to the method according to the invention for the production and/or storage of a liquid provided for drinking consumption or of a pre-product for such a liquid, initially a liquid container 10 is provided, which satisfies the basic requirements mentioned in the preceding paragraph (step (i)). Then, at least a partial section of the liquid container 10 is cooled down with respect to the temperature of the surrounding air atmosphere (step (ii)). Thereafter, a liquid is filled into the liquid container 10 that has been cooled down (step (iii)). Finally, a step of a chemical and/or biochemical conversion of the liquid that has been filled in is initiated, such as a fermentation or a conversion of sugar to alcohol, so as to generate the liquid or a pre-product for it (step (iv)). During the chemical and/or biochemical conversion, no further measure (or process) for cooling the liquid container 10 and/or the liquid residing in the liquid container 10 is taken (or performed).
The cooling down in step (ii) may be achieved automatically in the context (or course) of a temperature equilibration in a room (or environment) that is blocked from sunlight and heat irradiation. A suitable room may be at least partially situated under the surface of the earth. In the production of wine, a wine cellar may be a suitable room. The cooling down may occur to (or into) the temperature range of from 6° C. to 12° C., preferably to the temperature range of from 8° C. to 10° C.
The liquid container 10 may comprises a sheath section 26 and a bottom section 22, and the cooling down may comprise a cooling down of at least a partial section of the sheath section 26 and the bottom section 22. The liquid container 10 may further comprise a lid 36, and the cooling down may comprise a cooling down of at least a partial section of the lid 36.
In the method according to the invention, subsequent to the steps (i) to (iv) mentioned above, in the liquid container 10, further conditioning and/or treatment steps may be initiated, performed and/or awaited for/with a pre-product obtained in step (iv), such as a maturing process, by which the liquid to be provided for drinking consumption is finally generated.
The liquid may an alcohol-containing liquid, such as wine, fruit wine, or another beverage that can be made from the juice of grapes or fruits, or schnapps, whisky, beer, or a mixed beverage.
It should be noted that the term “comprising” does not exclude other elements or steps and the article “a” or “an” does not exclude a plurality. Also, elements described in association with different embodiments may be combined.
