In the production of wine, large amounts of carbon dioxide and other gasses are formed in and absorbed by the wine solution during fermentation and leave a rather bitter taste in the wine. Carbon dioxide is a colorless gas produced during the fermentation and wine makers store the wine in carboys, barrels, and other containers to allow the carbon dioxide to escape from the liquid of the wine. The longer period of aging the wine generally develops a softer tasting wine. The aging process generally results in improving the quality of the wine and increasing the value of the wine.
Amateur wine makers have resorted to the use of stirring equipment to agitate the wine to cause foam and some carbon dioxide to be formed on the surface of the wine, thereby driving away some of the carbon dioxide and, therefore, enhancing the taste of the wine. Others have used the application of a vacuum pump to the container of the wine, such as in the typical wine bottle, for the same purpose, to apply a low air pressure inside the bottle and to the wine, inducing the carbon dioxide and other gasses to separate from the liquid of the wine.
While all of the above procedures have been successful to some extent, there still is a demand for wine that does not contain undesirable amounts of carbon dioxide and other gasses that affect the taste of the wine.
Accordingly, it would be desirable to have a convenient and expedient means for the consumer to be able to reduce the carbon dioxide and other gasses contained in bottled wine.
Briefly described, this disclosure teaches a method and apparatus that may be used by the consumer for reducing the amount of carbon dioxide and other gasses contained in bottled wine, thereby enhancing the taste of the wine and providing the consumer with control of the gas reduction process for different wines. The gas removal usually results in changes in the wine, such as in the aroma, mouth feel, taste, and finish of the wine.
By use of this process, the degassing of the wine may be achieved faster than it normally would be when using a standard method recommended by manufacturers of homemade wine kits. It is possible that in the situation of degassing a 750 ml. bottle of homemade or commercial wine, the degassing process disclosed herein will take approximately one minute when using approximately 20 one-half inch diameter ceramic balls as shown in
The process of degassing bottled wine as disclosed herein may include the steps of inserting a solid item having a rough exterior surface formed of cordierite or other inert material into a container partially filled with wine to a level below the surface of the wine in the container, closing the container from the atmosphere, and applying a subatmospheric pressure to the interior of the container. The pressure drawn in the wine causes nucleation of carbon dioxide in the wine at the rough exterior surface formed on a solid inert item such as a cordierite item. The solid inert item having the rough exterior surface may have a shape selected from the group consisting of a solid rectilinear cylindrical shaft with a rough, granular or corrugated external surface. The solid inert item may comprise members attached in series on a connecting cord or rounded solid shapes.
The process to be practiced as disclosed herein may include the steps of inserting a solid rectilinear rod having a rough surface texture, preferably formed of cordierite, into a bottle of wine or other container that is partially filled with the wine to a level below the surface of the wine, supporting the rod with an adapter plug at the opening of the bottle or container of wine so that the adapter plug suspends the cordierite rod in the wine in vertical orientation, and then withdrawing gas from the bottle or container through the adapter plug. This creates a pressure in the container below atmospheric pressure, thereby inducing nucleation of the carbon dioxide in the wine at the surface of the cordierite rod.
Another form of the invention is the holder for the cordierite rod that attaches to opposite ends of the rod and exposes a major portion of both the length and circumference of the rod to the wine in the container or bottle, making available a large portion of the cordierite rod to contact with the wine in the container or bottle.
Another feature of the invention is the use of a solid inert material having a coarse exterior surface of a size and shape suitable for inserting into a bottle of wine, coupled with a vacuum pump for reducing the pressure of the atmosphere within the bottle/container to a level that induces nucleation of carbon dioxide in the wine in contact with the insert, with bubbles of carbon dioxide formed that rise to the level of the liquid, above the wine in the bottle.
Other objects, features, and advantages of this invention will become apparent upon reading the following specification when taken in conjunction with the accompanying drawings.
Referring now in more detail to the drawings in which like numerals indicate like parts throughout the several views,
In the embodiment illustrated in
As illustrated in
While the corrugations of
The mounting socket 35 and the retaining socket 36 both include internal recesses, such as downwardly facing recess 38 in the lower portion of mounting socket 35 and the upwardly facing recess 39 in the retaining socket 36 so that the end portions of the gas separator rod 22 fit into the recesses 38 and 39, and the gas separator rod 22 is firmly held at its ends to the separator rod holder 23.
As best shown in
As illustrated in
When the wine degassing apparatus 20 is to be placed in use, the gas separator rod 22 is mounted in the separator rod holder 23 as illustrated in
Once the wine degassing apparatus is in place, as shown in
The withdrawal of gas upwardly from the wine bottle 10 applies a subatmospheric pressure inside the bottle, to the surface of the wine. This, in turn, generates a lower pressure in the liquid wine, tending to degas the wine by withdrawing gas that includes carbon dioxide from the liquid, expelling the carbon dioxide to the atmosphere. The carbon dioxide and other gasses are formed in bubbles about the surface of the gas separator rod shown at 44 in
In a typical situation, the internal pressure of the gas into the wine bottle 10 is reduced to 600 mm Hg, or approximately 600 mm Hg lower than atmospheric pressure. The amount of reduction of pressure inside the bottle is controlled by the user of the invention, and the user of the invention usually will observe the bubbles formed in the wine that surround the gas separator rod 22.
While the irregular surface 28 of the gas separator rod 22 is shown as vertically oriented corrugations, other irregular shapes may be formed on the surface of the gas separator rod 22, such as, but not limited to, a series of circular protrusions or a grainy surface.
The line 52 has a distal end 34 and the beads 50 will be positioned adjacent the distal end of the line, and the proximal end 54 of the line 52 is long enough to extend through and out of the neck of the wine bottle. An enlarged object 56, such as a ring, may be attached to the proximal end of the line outside of the bottle to prevent the proximal end of the line from entering the bottle. With this arrangement, the beads 50 may be withdrawn from the bottle without spilling the wine.
The line 52 may be thin enough to allow the line to be extended through the neck 58 of the wine bottle and through the opening 60 of the bottle and the vacuum pump 62 and an adapter 64 mounted on the opening of the wine bottle to form a seal to prevent the passage of atmospheric air through the opening of the bottle. This allows for a snug seal of the opening 60 of the wine bottle, and also allows vacuum pressure to be developed in the bottle by operating the vacuum pump 62. When it is desired to remove the ceramic beads 50 from the bottle, the vacuum pump 62 and adapter 64 are removed from the bottle and the proximal end 54 of the line 52 may be drawn upwardly to lift the ceramic beads 50 out of the bottle. This expedites using the product and cleaning the product.
As previously described, the beads 50 of
Cordierite is formed of orthorhombic mineral and is a silicate of magnesium, aluminum, and sometimes iron, and may be found in granites and in metamorphic rocks that form under relatively low pressure conditions. A chemical formula for cordierite is (MG, FE)2AL4SI5O18.
The gas separator rod 22 may be between 6 and 9 inches in length for use in wine bottles of conventional size (750 ml.). Other dimensions of the gas separator rod may be used to fit wine bottles of different sizes. It is desirable to submerge as much of the surface of the gas separator rod as practical to expose the maximum amount of surface of the gas separator rod to the wine.
Although preferred embodiments of the invention have been disclosed in detail herein, it will be obvious to those skilled in the art that variations and modifications of the disclosed embodiments can be made without departing from the spirit and scope of the invention as set forth in the following claims.
