The field of the invention in general relates to containers for aging liquids, such as beverages, and methods of making and using them.
There is no admission that the background art disclosed in this section legally constitutes prior art.
Presently, many beverages and other food products are aged in wooden casks or barrels as part of the production process. These wooden casks are of various sizes, such as one common size that contains around 53 gallons of liquid. Beverages include alcoholic beverages such as wine and beer, and nonalcoholic beverages such as coffee and tea. Distilled beverages such as whiskey, scotch and bourbon are also aged in wood casks or barrels. For bourbon production, the requirement is that distilled (ethanol) alcohol from a corn mixture must be aged in virgin (new) oak casks for at least two years and a day. Typically, the casks are made of American white oak wood. Scotch and whisky are also aged in oak casks that are not necessarily virgin. Many manufacturers purchase used bourbon casks to age their products in to add flavor profiles.
Various factors determine the flavor and color of the end product including the environment and length of time aging in the cask. For example, the aging process is greatly influenced by the type of oak used, the char level applied (burning of the inside of the cask prior to filling), and the air temperature and humidity the cask is exposed to in the warehouse as it ages.
As part of the aging process, a portion of the liquid is lost through evaporation of alcohol and water through the wood of the cask, and the proof (alcohol-by-volume) of the beverage will drop slightly. The amount of this evaporation, known as the Angel's Portion, depends on temperature and humidity and can range from around 2% to 25% of the volume of liquid in the cask per year. Regarding the temperature environment, warm climates can cause faster reactions, and the aging will cause changes more quickly but more harshly, occasionally removing desirable components as well. Because wood is a porous product, barrels can “breathe,” expelling gas during the day when the temperature is warmer, and drawing gas in at night when the temperature is cooler. This breathing process causes the liquid to circulate and allow the wood to add flavoring to the aging beverage, but aging beverages in uncontrolled temperature environments may add uncertainty to the time required and the amount of flavors added into the beverage. In order to better control these environmental conditions, barrels are usually stored in rackhouses or underground cellars where temperatures can be regulated and climate changes minimized.
Further, the use of wooden barrels can create other issues during the aging process. For example, wooden barrels are flammable, and are often stored in large numbers (often, many thousands) in huge warehouses, and so present a significant fire risk. If a fire does occur, the cost to the manufacturer can be significant. For example, in 2018 a fire in a single warehouse in Kentucky destroyed over 20,000 barrels of bourbon (around 3.5 million bottles), thus costing the bourbon maker millions of dollars.
Thus, it would be highly desirable for a method of aging beverages that is impervious to most external weather conditions and be stored outside of a normal aging warehouse to allow wider temperature fluctuations to impact the aging process. There is also a need for a beverage aging system that can recapture evaporated alcohol to be condensed and form a secondary product from the aging process. Further, there is a need for a beverage aging system that can reduce the fire danger due to the presence of wooden casks.
In order to better understand the invention and to see how the same may be carried out in practice, non-limiting preferred embodiments of the invention will now be described with reference to the accompanying drawings, in which:

Referring now to the drawings, and more particularly to
The container system 10 may also include one or more input/out valves such as input valve 41 and output valve 46 that allow the insertion and extraction of gases or other mediums into a space formed between the container body 14 sealed around a barrel 75.
In an embodiment, the container body 14 is generally barrel-shaped in order to conformally enclose a beverage aging container such as an oak barrel. In other embodiments, the container body 14 may be various shapes such as square, rectangular, round or others so that the container body 14 completely encloses the barrel 75 with an airtight seal. The container body 14 may comprise a suitable rigid material such as metal, plastic, composite or other suitable material. The container body 14 should be sturdy enough to provide support for the enclosed barrel 75 and to be stored in a warehouse or other industrial environment.
The container body 14 may also include one or more spacer channels 55A on an inner surface of the container body upper portion 15 and one or more spacer channels 55B on an inner surface of the container body lower portion 19. In an embodiment, the channels 55A and 55B may comprise a generally rectangular tube shape comprising three sides and having one open side. The spacer channels 55A and 55B are sized to hold a spacer 59 that is inserted into the channels. In an embodiment, one or more other spacers 59 may be employed located on an inner portion of the container body top portion 23 and an inner portion of the container body bottom portion 28. The spacer channels 55A and 55B and the spacers 59 may comprise a suitable rigid matter such as metal, plastic, wood, composite or other suitable material. The spacer channels 55A and 55B and the spacers 59 may be slightly curved in shape to substantially conform to the shape of the barrel 75.
The container system 10 may also include one or more input/out valves such as an input valve 41 and an output valve 46 disposed through the inner portion of the container body 14 for allowing insertion or extraction of gases or other mediums into the space located between the barrel 75 and the container body 14. The pressure of the gases located in the space may be measured by a pressure gauge 50 disposed through the container body top portion 23. In an embodiment, gases, such as air, oxygen or inert gases such as nitrogen may be inserted through the input valve 41 at normal atmospheric pressure or elevated into the space atmospheric pressures to control the amount of alcohol that evaporates out of the barrel 75. The output valve 46 may be used to extract some or substantially all of the gases located in the space to form a vacuum. Such a vacuum may accelerate the aging process of the liquid and enhance the flavor over a shorter time period than conventional techniques.
The container system 10 may also include an environmental control unit 63 that may be disposed on an inner portion of the container body bottom portion 28. The unit 63 provides heating and cooling to the barrel 75 to control the temperature of the liquid aging therein. The unit 63 may include an electric cord 69 for providing electric power.
The container system 10 may further include one or more agitators 68 that are inserted into the barrel 75 for agitating the liquid while undergoing the aging process. The one or more agitators 68 help to ensure that the liquid does not stagnate in the barrel which would result in more flavoring occurring in the liquid in closer proximity to the inside of the barrel 75. In an embodiment, the agitators 68 may comprise one or more magnetic stirring bars that can be operated and programmed by a user with a remote control to circulate the liquid within the barrel for even temperature throughout the liquid.
For use of the container system 10, spacers 59 are inserted into the channels 55A and 55B, a spacer 59 and an environmental control unit 63 are disposed on the inner portion of the container body bottom portion 28, and a spacer is disposed on the inner portion of the container body top portion 23. If desired, one or more agitators 68 are disposed within the barrel 75. Next, the barrel 75 is positioned inside the container body lower portion 19 and secured by the spacers 59 located therein. This step may be accomplished while the container body lower portion 19 is in a horizontal position, a vertical position, or other suitable position. Then, the container body upper portion 23 is placed over the barrel 75 and onto the lower portion 19 and secured by engaging the male portion 21A of the screw element 21 with the female portion 21B with a twist of around 15 degrees so that the seal is airtight. Finally, the upper portions 33A and lower portions 33B of the latch apparatus 33 may be engaged to further provide an airtight fit. Also, an optional strap may be positioned around the container body 14 where the upper portion 23 engages the lower portion 19 to further ensure an airtight seal.
After an airtight seal is created, the input valve 41 allows insertion of gases such as air, oxygen or inert gases such as nitrogen into the space outside of the barrel 75 at normal or elevated atmospheric pressures to control the amount of evaporating alcohol and the output valve 46 allows extraction of some or substantially all of the gases located in the space to form a vacuum. The pressure of the gases located in the space may be measured by a pressure gauge 50, and in an embodiment, the pressure may be provided up to around three atmospheres. The temperature of the liquid in the barrel 75 may be controlled by the environmental control unit 63.
