Distilled spirits traditionally were stored and shipped in wood casks as these were the most cost effective and appropriate containers available. Today it is still common in industry to find extensive warehouses filled with liquids being aged in barrels for extended periods of time. Ageing distilled spirits in wood can take many years to provide a desired flavor profile, can lower yield due to evaporation, and does not guarantee a consistent product. Hence there is a current trend to accelerate aging of distilled spirits by various methods.
According to one aspect methods are provided related to production and improved maturation of distilled spirits of all alcoholic strengths and types to yield a palatable and mature product at least comparable to commercially available products yielded by traditional aging methods and/or systems.
According to another aspect systems and/or devices and/or materials are provided related to production and improved maturation of the distilled spirits comparable at least to products yielded by traditional aging methods and/or systems.
The term “Distilled Spirit” refers to any fermented solution comprised of but not limited to: grains, malted grains, legumes, fruit, sugar cane, distilled at least one time. “Maturation” refers to improving sensory characteristics of any distilled spirit by some process, such as holding the liquid in containers, generally made of wood, usually oak casks, for a period ranging from few days to a significant number of years. The type of material the container is made from (and specifically the type of wood used for a cask or added for the container, if any), charring level of wood (if any), the liquid previously held in said cask or container, the porosity of said container, how many times the cask or container was previously filled, and the amount of time liquid was held in said cask or container all strongly affect the properties of the final aged product.
“Unaged or Partially Aged” refers to distilled spirits which have not yet been matured or have been matured for an amount of time which does not yield a finished product.
The term “catalysis,” relates to a reaction occurring with a “catalyst,” which accelerates reaction rates without being consumed in the reaction and can act in the reaction repeatedly. In this case the term “catalyst” refers to heterogeneous or homogeneous catalytic materials or mixtures thereof, where “ligand” refers to a molecule or functional group bound to a central metal atom.
“Intermittent electrical resistance pulses” are defined as providing heat pulses to a distilled spirit in time lengths of 0.1 seconds to 600 seconds or more, not necessarily of equal temporal lengths for each subsequent pulse. “Continuous heating” refers to the application of energy without pulses of energy.
“Gaseous or Liquid state” refers to the physical phase in which the distilled spirit is in contact with heating elements/catalytic materials/dispersion system/container or other articles thereof. The distilled spirit can interact with articles in both liquid and/or gaseous phases.
“Dispersion System” refers to a system through which a distilled spirit is passed to provide a physical change to the spirit.

The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tools and methods which are meant to be exemplary and illustrative, not limiting in scope.
Features of the proprietary improved ageing systems are described below.
Metal catalyzed reactions are well known and widely used in chemistry and chemical engineering [Y. Zhu et al., J. Org. Chem. 2013, 78, 9898-9905], [Liu et al., Org. Biomol. Chem., 2014, 12, 2637]. Catalysts may be employed as metals, alloys, or ligands [Zeng et al., https://www.intechopen.com/books/chemical-kinetics/recent-developments-on-the-mechanism-and-kinetics-of-esterification-reaction-promoted-by-various-cat], to accelerate the progress of reactions.
In particular, it has been shown that Cu can double the concentration of common esters found in distilled spirits during distillation [Larson, V. F., Yeast Biotechnology, 1987, 501-531].
Iron oxide nanoparticles have been shown to catalyze esterification reactions for carboxylic acids in the presence of alcohols [Rajabi et al., Materials 2016, 9, 557], alumina-supported Cu(II), Co(II), and Fe(II) complexes can be used as catalysts for esterification [Hossain et al, Bioresources 2018, 13(3) 5512-5533] and Pd/C catalyzed hydrogenation has been shown to catalyze esterification reactions for carboxylic acids with various alcohols [Aavula et al., Tetrahedron Letters 54 (2013) 5690-5694], and SO4 2-/TiO2/γ-Al2O3 has been shown to be effective as a solid acid catalyst for esterification [Yaun et al., Cjche (2018)]
In addition, various carbon based catalysts can be utilized for esterification reactions. Multiwalled carbon nanotubes and carbon xerogels, which exhibit excellent performance as solid acid catalysts for esterification of acetic acid and ethanol [Rocha et al., Catalysis Today 218-219 (2013) 51-56], and carbon based solid acid catalyst was shown to be used as a potential catalyst for esterification reactions [Rathod, 2017 J. Chem. Environ. Vol. 21, 11].
We have discovered that using either a certain single catalyst or a combination of one or more certain catalysts (105, 106, 113, 114 in kit 1000, 205, 206 in kit 2000, 305 in kit 3000), such as columns 4-12 transition metals, column 13 boron group, column 14 carbon group, and any mixtures thereof, after completion of distillation, produced a product with very desirable attributes by substantially enabling changing the level of at least one maturation congener in the distilled spirit. For example, in some embodiments our whisky samples which are 2.5 weeks old get consistent age estimates between 4 and up to 18 years old from professional organoleptic judges. In addition, analytical results strongly indicate that the chemical compositions of our samples are comparable to industry standard whiskies.
Moreover, although in some embodiments the conditions, reactants, and/or reagents significantly differ from the use of catalysts in the above-referenced publications, we hypothesized correctly that metal catalysts would be highly useful in improving ageing processes of distilled spirits.
For example, we have surprisingly discovered that the use of copper post-distillation for proprietary improved aged distilled spirits, as described in further detail below, strongly indicates that the chemical compositions of our samples are comparable to industry standard whiskies
The catalyst materials may be in contact with the distilled spirit in liquid or vapor phase or mixtures thereof.
Some other embodiments comprise ceramic membranes as a catalyst. Some ceramic membranes, such as Al2O3 or zeolite based materials, are known for acceleration of reaction rates for esterification [Bruggen, Handbook of Membrane Reactors, Reactor Types and Industrial Applications Volume 2 in Woodhead Publishing Series in Energy 2013, Pages 107-151], such as enhancement of esterification from acrylic acid with butanol [Emine et al., J. of Polytechnic 2017, 20, 437-440], which is analogous to many reactions that are taking place during distilled spirit aging. However, the referenced membranes have not previously been shown to be effective in relation to reactions taking place during distilled spirit aging.
Certain transition metals, such as Pt, Pd, Ni, Cu, Ag, Au, Ru, Rh, Ir, Pd, Ni, V or mixtures thereof [H. Sellers and E. Shustorovich, Surface Science 356 (1996) 209-221] may react in some conditions with compounds such as sulfur compounds in both the liquid and gaseous phase. We have found that during the aging some catalytic materials, in particular several of the group 8 to 12 transition metals, surprisingly serve in some embodiments both as catalysts and as reactive materials; for example act both as a catalyst for increased reaction kinetics of esterification reactions and as a reactant for the precipitation and/or evaporation of deleterious sulfur compounds. We have discovered that utilizing such catalytic materials may accelerate the maturity and significantly improve the organoleptic properties of the final product compared to traditional methods. These catalytic materials may remove unwanted deleterious sulfur compounds, such as SO2, from the distilled spirit which are converted into less-deleterious compounds, evaporate, are absorbed, adsorbed, and/or precipitate out of solution.
For some embodiments two or more different catalysts may be used in tandem, for a better catalytic effect. For example, in some embodiments there are at least two catalysts, at least one of which contains Fe and at least one that does not contain Fe but one of the non-Fe materials indicated above.
We have discovered that in some embodiments controlling distilled spirit and/or apparatus temperatures while incorporating catalytic materials significantly accelerates aging times and provides a superior product. Temperature may be controlled via multiple heating apparatuses (104, 112, 204, 304), in various locations inside a main container (100, 200, 300) and/or in external containers. Heating apparatuses may be metal or ceramic, porous or impervious, catalytic or non-catalytic or a combination of one or more of materials, and may be in contact with a gas phase/headspace in the headspace area (134, 228, 308) or a liquid phase in a lower area (135, 229, 309) in the main container (100, 200, 300) or both. Thermal energy is supplied to the spirit via a respective heating apparatus (104, 112, 204, 304) either by intermittent electrical current pulses, with an energy output between 0.1 to 1500 W per liter of distilled spirit in the main container, or constant energy output (such as via a conduit) by steam/liquid flow, with a maximum energy output between 0.1 to 15000 W per liter of distilled spirit in the main container 100, 200, 300 until desired pre-determined temperature (0° C. to 99° C.) of the distilled spirit and/or catalytic material 0° C. to 250°) in the
container 100, 200, 300 is reached.
Liquid distilled spirit temperature may be monitored by a first thermistor/thermocouple (109, 209, 306) which is connected via a first connector (110, 210, 307) to a control unit (101, 201, 301), and energy may be applied to maintain a desired pre-determined liquid distilled spirit temperature (e.g., 0° C. to 99° C.) via a temperature control apparatus, either by intermittent electrical current pulses or constant energy output by steam/liquid flow.
Gaseous distilled spirit temperature may be monitored by a second thermistor/thermocouple (107, 207) which is connected via a second connector (108, 208) to the control unit (101, 201, 301) and energy may be applied to maintain the desired pre-determined gaseous distilled spirit temperature (e.g., 0° C. to 250° C.) via a temperature control apparatus either by intermittent electrical resistance pulses or constant energy output by steam/liquid flow.
It is possible to heat and/or cool the distilled spirit via a temperature control apparatus with one or more discrete catalytic materials (105, 106, 113, 114, 205, 206, 305) acting as the main thermal energy transfer entity or mixed with non-catalytic materials (such as a metal alloy), or plated on, or adhered to a thermal energy transfer apparatus. It is possible to heat and/or cool the substrate strictly via a singular source or have multiple temperature control sources: one or more catalytic, one or more inert or a mix thereof. As an example: an inert heating element may heat the spirit and a catalytic heating element may provide a different heating profile that may function in parallel.
For example, in heating with a metal heating element: The catalytic material can be a metal sheath (e.g., Pt, Pd, Ni, Cu, Ag, Au, Ru, Rh, Ir, Pd, Ni, V) which conducts heat, or the heating element can comprise an alloy of a non-catalytic and catalytic material, such as but not limited to copper plated on steel, silver plated on nickel, or Pt, Pd, Cu, Ti, Ag, Ag, Ru, Rh, Ir, Pd, Ni, and/or V particles adhered to a surface of a heating element.
In the case of the kit embodiment 1000 schematically illustrated in
The main container in which the distilled spirit is held may or may not contribute to the quality of the final product. Traditionally containers were wood based, most commonly oak, and prolonged travel/storage times allowed the alcoholic liquid to penetrate the wood and extract favorable attributes over time. Depending on the desired outcome for the particular embodiment the main container (100, 200, 300) used for aging distilled spirit can comprise one or more materials such as organic (e.g., wood based), metal or metal alloy (e.g., stainless steel), ceramics, glass, thermoplastics or mixtures thereof. The material used for the main container may be inert or reactive, porous or impervious, therefore either allowing for chemical interaction between the container and the spirit or preventing chemical interaction between the spirit and external effects.
Some exemplary uses are:
Wood based containers, traditionally utilized for beer, wine, and spirits;
Stainless steel containers, utilized for aging some wines and for use as storage containers in industry;
Ceramic jugs, traditionally utilized for aging rice or sorghum spirits;
Glass, utilized for aging wine in the bottle before consumption;
Thermoplastics, ubiquitous in the spirit industry for storage and aging.
An important component of traditional barrel-aging of distilled spirits is diffusion of oxygen from the external environment into the barrel, which allows for many beneficial redox reactions to occur.
Embodiments may provide oxygenation of the liquid via a dispersion system. Reaction kinetics, for reactions such as esterification, can be increased via an input of external energy (e.g. ultrasonic waves or electromagnetic radiation) to the liquid before and/or during reflux and reintroduction into the bulk liquid in the main container.
In addition, a membrane can be used to further separate molecules and in some embodiments ceramic pervaporation membranes are used via an opening or nozzle instead of convecting the liquid [Bruggen, Handbook of Membrane Reactors, Reactor Types and Industrial Applications Volume 2 in Woodhead Publishing Series in Energy 2013, Pages 107-151].
In some embodiments liquid spirit is drawn from the bulk substrate (135, 229) into the liquid dispersion system (115, 211) via a tube with or without controllable one way valve/s (117, 213) by a pump (118, 214) and is dispersed via an opening (119, 215) into the gaseous environment (121, 217) of an internal container (120, 216).
Not having a one way valve allows introducing various ratios of gasses into the main container 100, 200 while processing the spirit in the dispersion system 1200, 2200.
The gaseous environment (121, 217) of the internal container (120, 216) may be air, an oxygen rich gas, an inert gas, a reacting gas, dry, with varying humidity, or a mixture and is regulated by an inlet/outlet control system (122, 218), which in some embodiments comprises a gas flow control valve and in optional embodiments gas/mass flow meters. This inlet/outlet control system 122, 218 can either be open to the atmosphere, or connected to a gas tank (not shown) to control the internal gaseous environment of the dispersion system, such as a higher ratio of O2/N2.
The mentioned gas mixtures may be pressurized (0.1 Bar to 250 Bar) or vacuum pressure (0 to −1e−4 mBar) may be employed via the inlet/outlet control system (122, 218). Gaseous mixtures or pressure changes may directly affect the gaseous headspace phase in the headspace area (134, 228, 308) in the main container (100, 200, 300), via controllable one way valves inside the dispersion system inlet (117, 213) and outlet (128, 222) tubes/pipes. The internal container (120, 216) may be made of organic, metallic, thermoplastic, or ceramic material or combinations thereof, and may be porous or impervious and may have qualities of membranes used for separation of chemical species, or combinations thereof.
Temperature of the gaseous environment (121, 217) is measured by thermistor/thermocouple (123) and the dispersed spirit is condensed under reflux (127, 221) and flows back into the main container (100, 200) via an outlet tube (128, 222) with or without a controllable one way valve and reconstitutes into the substrate as a liquid (129, 223).
We refer now to the kit embodiment 1000 schematically illustrated in
The dispersion system 1200 comprises an internal container (120), a control unit (115) in operational communication with the internal container 120, a siphon tube (117) with or without a controllable one way valve for drawing distilled spirit from the main container 100 into the internal container 120, a pump (118) for pumping liquid spirit from the main container 100 into the dispersion system 1200 via the siphon tube 117, and a nozzle (119) operationally coupled to the pump 118 and configured to allow effectively dispersing the spirit in the internal container 120. An area of the internal container 120 is designated as an internal gaseous/vacuum environment (121).
The dispersion system 1200 further includes a gas composition and pressure/vacuum inlet/outlet control unit (122) in operational communication with the environment surrounding the internal container 120 and the internal container 120, in particular the internal gaseous/vacuum environment (121), a thermistor/thermocouple (123) in operational communication with the internal container 120, in particular the internal gaseous/vacuum environment (121), wiring (124) connecting the thermistor/thermocouple 123 to the control unit 115, an internal energy source (125) such as an electromagnetic/thermal radiation emitter, an external energy source (126) such as an electromagnetic/thermal radiation emitter, both operationally connected to the thermocouple/thermistor and the internal container 120, a spirit reintroduction tube (128) with or without a controllable one way valve, and a seal (116) sealing the siphon tube 117 and the reintroduction tube 128, preventing leaks between the main container 100 and the internal container 120.
During operation, the dispersion system 1200 produces a reconstituted post-dispersion treatment distilled spirit (129) in liquid or gas form, which drips into the gaseous headspace area 134 in the main container 100. Operation of the dispersion system 1200 on the substrate forms a reflux 127 of dispersed liquid in the internal container 120.
Absence of a one-way valve in the drawing tube 117 allows additional reflux in the pipe 117, whereas a one-way valve prevents backflow of liquid into the main container 100.
Similarly, in the case of the kit embodiment 2000 schematically illustrated in
Temperature gradients in liquids create convection cells which mix the solution slowly. However, via convection alone longer heating times are required to reach the desired set temperature of the liquid, and therefore a circulation system can greatly increase the efficiency of heating. In addition, more mixing generally means faster reaction kinetics, and a more homogenous product. A circulation system 1300, 2300, and 3300 is sealed in the main container (100, 200, and 300) by a bung/seal/flange (132, 226, and 312). Liquid spirit is pumped by a pump (133, 227, and 313) via an inlet tube (130, 224, and 310) and back into the bulk liquid substrate out an outlet tube (131, 225) or into the gaseous headspace spirit out an outlet tube (311). Circulation can take place with piping external to the main container (100, 200), as in
A kit 1000, as shown in
i. The liquid distilled spirit area (135) and the spirit therein is heated by a continuous heating steam/liquid conduit heating apparatus (112) to a pre-determined temperature between 35 to 90° C. via a stepwise heating regimen, preferably of 5° C. steps, until equilibrium is reached.
ii. The headspace gaseous distilled spirit area (134) and, when there is substrate in the main container 100, the gaseous phase therein, is heated by a heating apparatus (104) utilizing electrical resistance to heat in conjunction with heating the liquid spirit. The heating is by heat pulses (01 second to 600 seconds) which continues with no relation to liquid spirit temperature.
iii. Once the liquid distilled spirit reaches the desired temperature, pre-determined set temperature is maintained by the thermistor/thermocouple (109) measurements in relation to temperatures set on the front panel (102). Upon reaching the desired equilibrium temperature of the liquid spirit, a pump (118) draws liquid substrate into the liquid dispersion system (1200), via a pipe (117) made of a material selected from one or more of the following: metal, plastic, glass, or ceramic.
Air is supplied by an inlet/outlet control system (122) at atmospheric pressure. Liquid substrate is sprayed out of a nozzle 119 which includes an insert made of a porous material into a porous membranous internal container (120) made of a material selected from one or more of metal, glass, plastic, or ceramics. Energy input is provided by an energy sources (125), (126) comprised of but not limited to: electromagnetic radiation with a wavelength between 380 to 700 nm, located either inside the inner container 120 or outside thereof, to accelerate reaction kinetics of chemical reactions such as, but not limited to, acid catalyzed esterification, and oxidation reactions. The spray refluxes into a liquid (127) and flows back into the cask (main container 100) via a pipe (128). The liquid dispersion system 1200 is sealed in the main container (100) by a seal (116). Circulation of the liquid spirit is performed from the initiation of the heating regime by a pump (133) via an inlet (130) and outlet (131) pipe and the circulation system 1300 is sealed in the main container 100 by a flange (132).
