FIELD

[0001] The present invention is directed to the wooden barrel aging of alcoholic beverages such as distilled spirits, wine, and beer, in which the barrel is covered by an article which allows the beverage to age in the normal manner while at the same time reducing the Angels Share loss resulting from liquid passing through the barrel and evaporating into the atmosphere.

BACKGROUND [0002] The present invention is directed to the wooden barrel aging of alcoholic beverages such as distilled spirits, wine, and beer. During typical wooden barrel aging of distilled spirits derived from grains and other farm sources, from 2 to 50 wt % or more of the distilled ethanol and water in the mixture diffuses between and through the wooden barrel components (staves and heads) and thereafter evaporates into the surrounding atmosphere. The diffusion and evaporation continues throughout the aging period, which can be from a few weeks or months up to 20 years or more. The extent of evaporation depends on the initial alcohol content of the distillate or fermented product, the duration of aging in the wooden barrels, the condition of the barrels, ambient conditions, etc. The alcoholic beverage industry defines this loss as the "angels' share."

[0003] The amount of water, ethanol, etc lost through evaporation when aging distilled spirits in 53 gallon white oak barrels over periods of time ranging from 1 to 20+ years ranges from about 2% per year to about 10% per year, depending upon the ambient conditions during aging, e.g., depending upon the climate. The distillate may be weaker upon emerging from the distillation process than it is after aging for 10 years, as ethanol loss can be greater than water loss. The loss of ethanol during aging has adverse effects over and above the loss of the alcohol itself. The release of alcohol into the atmosphere around the barrels may produce an explosion hazard, as a high ethanol content in the air may ignite explosively if subjected to spark or flame. Evaporated ethanol released into the ambient environment also serves as sustenance for black fungi and/or molds growing on warehouse walls, adjacent buildings, cars, etc.

[0004] For many decades, distillers have attempted to reduce the angels' share during aging of distilled spirits and wine in wooden casks. Barrels have been provided with coatings, including coating of the outer surface of barrel staves and/or barrel heads. Bonding agents have been used between the staves.

Barrels have been made from reconstructed staves having intermediate plies of non-porous material. Barrels have been placed inside bags made from various films, with or without evaporation of atmosphere from the bag before it is sealed closed.

[0005] It has been found that aging an alcoholic beverage in a barrel by completely enclosing the beverage-containing barrel in a packaging article comprising a film which is specifically designed for low ethanol transmission but relatively high oxygen transmission, allows the alcoholic beverage to age normally while at the same time significantly reducing Angels Share loss. Such a film, and its use around an alcoholic beverage aging barrel, are disclosed in USSN

14/599,820, entitled "Process For Reducing Ethanol Loss While Developing Desirable Organoleptics During Wooden Barrel Aging Of Alcoholic Beverage," filed 19 Jan 2015, and USSN 14/333,867, entitled Process For Reducing Ethanol Loss While Developing Desirable Organoleptics During Wooden Barrel Aging Of Alcoholic Beverage," filed 17 July 2014, both of which are hereby incorporated, in their respective entireties, by reference thereto.

[0006] However, it has been discovered that hermetically sealing such a film around an alcoholic beverage containing barrel may in at least some cases allow liquid to accumulate and remain between the outside surface of the barrel and the inside surface of the packaging article. The water in this outside-the-barrel liquid causes the barrel to appear to be wet, which is at least aesthetically undesirable. The presence of moisture between barrel and packaging article is also believed to contribute to rusting of the iron hoops around the barrel. The rusting of the iron hoops is believed to be at least part of the cause of the liquid turning an unsightly dark color. In addition to the adverse aesthetic effect of retaining dark liquid between the film and the outside surface of the barrel, the retained liquid between the outside of the barrel and the inside of the film has the potential of at least partially migrating back into the barrel and adversely affecting the organoleptics and/or color of the alcoholic beverage as it ages inside the barrel.

[0007] It would be desirable to find a way to age an alcoholic beverage in a manner that reduces the Angels Share while at the same time avoiding (i) retention of liquid between the barrel and an Angels Share reduction packaging article surrounding part or all of the barrel and any accompanying detrimental effects upon the beverage inside the barrel or detrimental effects on the barrel itself, and (ii) avoiding any accelerated rusting of the barrel hoops.

Summary

[0008] A limited contact assembly and process for making and using same have been discovered which can reduce the Angels Share loss while also reducing or eliminating the retention of fluid between the barrel and film around the barrel, and the associated potential for increased rusting of the iron barrel hoops, while at the same time allowing the liquid contents inside the barrel to age in a manner that generates organoleptic development in accordance with traditional, uncovered barrel aging. Moreover, the use of the limited contact assembly eases the process of covering part or all of the barrel with a cover.

[0009] It has been discovered that by having the tubular cover in limited contact with the barrel allows liquid between barrel and film to escape, as liquid or vapor, through passageways in the region in which the tubular cover is in limited contact with the barrel, thereby: (i) reducing or eliminating hoop rusting, (ii) reducing or eliminating the unsightly appearance of liquid trapped between the barrel and film, and (iii) reducing or eliminating any detrimental effect(s) which may occur due to the presence of the liquid between the barrel and the tubular cover. Moreover, it has been found that a significant portion of the reduction of Angels Share losses is maintained in spite of the open system present with limited contact between cover(s) and barrel.

[0010] At the same time that the passageways for escape of liquid allow avoidance of these detrimental effects, having the film (i.e., tubular cover) covering at least a portion of the barrel maintains a high ethanol concentration in the micro-environment between the barrel and the film, with relatively low rate of ethanol loss through the unsealed contact between the film and the barrel, compared with the rate of ethanol loss which would occur without the film covering the barrel. Maintaining a higher ethanol concentration in the micro-environment between the barrel and the film provides a micro-climate in which the gas surrounding the barrel is closer to being saturated with ethanol, thereby reducing the rate of evaporation of ethanol which has migrated to the surface of the barrel, with accompanying lowering of the Angels Share loss of ethanol to the

environment, providing the multiple advantages of greater quantity of aged alcoholic beverage, lower explosion hazard, and lower rate of mold growth due to lower concentration of ethanol in the atmosphere.

Detailed Description

[0061] As used herein, the phrases "top head" and "bottom head" refer to opposing heads (i.e., a first head and a second head) of a barrel, regardless of whether the barrel is in an upright position (i.e., vertical position, i.e., axis through centers of barrel heads in a vertical position), resting on one end thereof, or whether the barrel is in a horizontal position (i.e., axis through centers of barrel heads in horizontal position), with the bilge in contact with a support surface. Similarly, as used herein, the phrases "upper end" and lower end," used relative to the wooden staves, refer to opposing ends of the staves (i.e., a first end and a second end), regardless of whether the barrel is in an upright (vertical position) resting on one end thereof, or whether the barrel is in a horizontal position, with the bilge in contact with a support surface.

[0062] On the other hand, in the instances in which the barrel or the barrel- and-cover assembly is described as being in an upright position, the phrase "top head" refers to the barrel head at the so-oriented top of the barrel, and the phrase "bottom head" refers to the barrel head at the bottom of the so-oriented bottom of the barrel. Similarly, in the instances in which the barrel or the barrel-and-cover assembly is described as being in an upright position or vertical position, the "upper end," used with reference to the staves, refers to the ends of the staves connected with the top head of the barrel. Likewise, in the instances in which the barrel or the barrel-and-cover assembly is described as being in an upright or vertical position, "lower end," used with reference to the staves, refers to the ends of the staves connected with the so-oriented bottom head of the barrel.

[0063] As used herein, the phrase "means for gathering" refers to any and all means for maintaining at least a portion of the cover in a gathered configuration

(i.e., wrinkled, undulating, accordioned, overlapping, condensed, etc) and/or maintaining a portion of the cover in a folded configuration (i.e., pleated configuration). The means for gathering may (i) apply force to cause the gathering of a portion of the cover, as per an elastic strap and some clamps, or (ii) merely maintain a previously gathered or folded configuration in place, as per a pin, staple, pressure sensitive adhesive tape, etc. The means for gathering may extend all the way around the barrel or around on a portion of the barrel.

[0064] The cover can be film in the form of a flat sheet that is draped over the barrel or barrels, with the means for gathering maintaining the cover in a gathered or folded configuration in limited contact with the outer surface of all the barrels being covered. A cover comprising a tubing is preferred because it has less excess film than a cover that is a flat sheet.

[0065] Alternatively, the cover can be a film in the form of a flat sheet draped over the barrel or barrels, or in the form of a tubing, without the means for gathering maintaining the cover in limited contact with the outer surface of all the barrels being covered. For example, if six barrels in upright position are arranged with their longitudinal axes at the corners of a hexagon, with a seventh barrel in the middle, the centrally positioned seventh barrel can be covered by the without being maintained in limited contact with the outer surface of the seventh barrel, but will be in limited contact with a portion of the outer surface of six covered barrels arranged in the hexagon pattern. [0066] The means for gathering the tubular cover includes any means that gathers the tubular cover in a manner such that the tubular cover is held in limited contact with the barrel. Such means includes one or more of the following: elastic strap(s), clip(s), staple(s), pin(s), adhesive, and clamp(s). As used herein, the means for gathering can gather the excess film into a wrinkled configuration (such as an accordion configuration) or a folded configuration, i.e., with pleats, or a combination of a wrinkled configuration and a pleated configuration.

[0067] If the means for gathering comprises an elastic strap, the strap can be around the outside of the tubular cover, or affixed to the inside surface of the tubular cover, or confined inside a casing made by either folding the tubular cover back upon itself (i.e., folding to the inside or folding to the outside) and fastening the folded back portion to the remainder of the tubular cover and to form a casing enclosure. The elastic strap can go all the way around the open end of the tubing or only around a portion of the distance around the open end of the tubing.

[0068] Alternatively, the elastic strap can be used around a pad that the barrel rests upon when the barrel is in an upright position, with the pad resting upon the upper surface of a pallet. That is, the pad can be between the pallet and the barrel. The pad can have a portion which extends upward around the outside surface of one or more of the barrel staves. The elastic strap can be around the tubing, i.e., holding the tubing (i) in limited contact with the edge of the pad or (ii) in limited contact with an upwardly extending portion of the pad, or (iii) in limited contact with an upwardly extending portion of the pad which in turn holds the tubing against the staves of the wooden barrel.

[0069] The means for gathering can be an elastic strap that is present inside a casing enclosure provided at the open end of the tubular cover, i.e., the tubular article that covers the barrel. The casing includes all material surrounding the casing enclosure, including (i) any portion of the tubular material doubled back upon itself and a corresponding portion of the tubular cover doubled back upon to form the casing enclosure (ii) any separate article affixed to the inside or outside surface of the article together with a corresponding portion of the tubular cover covered by the separate article, and (iii) any separate article affixed to the outside surface of the tubular cover at a first location and fastened to the inside of the tubular cover at a second location, to provide a casing enclosure including the inside surface of the separate article and any portion of the tubular cover making up the inside surface of the casing enclosure.

[0070] An elastic band (i.e. , elastic strap, elastic cord, elastic tape, elastic fabric, or elastic ribbon) positioned inside the casing enclosure can be used to hold the tubular cover in limited contact against the barrel. The elastic band can be sized so that it can be stretched to a size large enough to pass over the maximum transverse perimeter of the barrel (i.e., the barrel bilge), but so that it contracts to a size small enough to hold the film in limited contact with the barrel at a desired location to allow the tubular cover to cover a desired surface of the barrel.

[0071] As used herein, the phrase "limited contact" (also referred to herein as "unsealed contact") refers to a level of contact which holds an end region of the cover against the barrel with the film being in a puckered and/or folded

configuration, in which the film contact with the outside surface of the barrel is neither watertight nor airtight (i.e., "unsealed contact"), with the contact leaving a plurality of passageways for otherwise trapped liquid (i.e., liquid which (i) evaporates from the surface of the barrel and condenses between the film and the barrel, and/or (ii) passes through the barrel in the liquid state, due to a leak or other migration through the barrel in the liquid state. As used herein, "limited contact" includes holding the end region of the cover in direct contact with the wood of the wooden staves and/or directly against a metal hoop around the wooden staves, or directly against another tubular cover having one or more open ends which in turn are held directly against the wood of the wooden staves and/or directly against a metal hoop around the wooden staves. [0072] The a liquid exit port can be perforations with or without hanging chads, slits, perforations, one or more valves (particularly one-way valves allowing fluid to exit but not enter or re-enter), or even passageways leading to a fully enclosed region separate from the chamber within which the barrel resides, the separate region having an absorbent to absorb and collect the fluid so that it does not migrate back out into the chamber in which the barrel resides, so that the fluid does adversely affect the barrel and/or the barrel hoops and/or the alcoholic beverage inside the barrel, be it comprising a distilled liquid product or a fermented liquid product therein.

[0073] In an embodiment, the cover has a closed end that covers the outside surface of a first barrel head and the outside surface of the staves, with the open end of the cover terminating at the stave ends connected to the second barrel head. Aging of the liquid in the barrel can be carried out with the covered, filled barrel in a horizontal position (as on warehouse racks) or in a vertical position, either stacked or with one or more barrels on a pallet. The covered barrel can be stored with the closed end of the cover covering the bottom head of the barrel, or with the closed end of the cover covering the top head of the barrel. If the closed end of the cover covers the bottom head of the barrel, the closed end of the cover can be provided with a liquid exit passageway.

[0074] In an embodiment, the tubular cover covers the outside surface of the first barrel head and the full length of the outside surface of the staves, and a portion of the second barrel head. The barrel can be stored for aging in a vertical orientation a horizontal orientation, or any orientation between vertical and horizontal.

[0075] In covering the first barrel head or both the first barrel head and a portion of the second barrel head, the tubular cover may or may not be in contact with the outside surface of either barrel head, as the staves extend further than the outside surface of the first barrel head and further than the outside surface of the second barrel head. That is, because the barrel heads are recessed relative to the ends of the staves, depending upon size and configuration, the tubular cover may or may not contact the outside surface of the first and/or second barrel heads.

[0076] FIG. 1 is a schematic perspective view of wooden barrel 20 in an upright position with upper head 22, chime 24, lower head and lower chime (not illustrated), staves 26, upper head hoop 28, lower head hoop 30, upper quarter hoop 32, lower quarter hoop 34, upper bilge hoop 36, lower bilge hoop 38, bung 40 (shown installed in a bung hole through wooden stave 26), and bilge 42. The hoops are held together with rivets 44 which hold end regions of the metal hoops together. Hoops 28, 30, 32, 34, 36, and 38 may each be held in place on the barrel with one, two, or more tacks (not illustrated) which pass through the hoops and a short distance into wooden staves 26. Bilge 42 is the widest part of barrel 20. Bung 40 is hammered into a passageway (bung hole) through a stave 26. Bung 40 can be can be made of wood, cork, rubber, silicone, polyurethane, etc.

[0077] FIG. 2 is a schematic perspective view of a barrel-with-cover assembly 46 comprising wooden barrel 20 in an upright position on pallet 50 with cover 60 thereon. Cover 60 has closed end 62 and tubular portion 64 terminating in open end 66 having casing 68 providing a casing enclosure which encloses a passageway within which is elastic loop 70 under tension.

[0078] FIG. 3 is an enlarged view of a portion of barrel-with-cover assembly 46 with the barrel 20 (for clarity of illustration, barrel 20, which is under cover 60, is not illustrated in FIG. 3) in an upright position on pallet 50 with cover 60 over barrel 20. Cover 60 terminates in open end 66, with the film from which cover 60 is made doubling back and affixed to itself (e.g., by heat sealing, adhesive, etc) to form casing 68 having therewithin a casing enclosure providing a confined domain within which is a loop of elastic strap 70 under tension. Puckering 72 of cover 60 at open end 66 is caused by open end 66 having an inside perimeter larger than the outside perimeter of the lower end of the barrel 20, as the means for gathering (in this case, the tensioned loop of elastic strap 70) forces the inside of casing 68 against the outer surface of the barrel 20 at open end 66. Open end 66 of cover 60 is maintained in limited contact against the outer surface of barrel 20 by the means for gathering.

[0079] FIG. 4 is a schematic perspective view of barrel-with-cover assembly 80 in which four barrels 82, 84, 86, and 88 are in upright position on pallet 90, with multi-barrel cover 92 covering barrels 82, 84, 84, and 88. Cover 92 has closed end 93 covering the top heads of all four barrels 82, 84, 84, and 88. Cover 92 also has open end 94, with the film from which cover 92 is made doubling back and affixed to itself to form casing 96 having therewithin a casing enclosure providing a confined domain within which is a loop of elastic strap 70 under tension. Puckering of casing 96 at open end 94 is present because open end 94 has inside perimeter larger than the outside perimeter of the shortest passageway around the combined lower ends of all four barrels 82, 84, 86, and 88 in their arrangement on pallet 90, as open end 94 must be large enough to pass over the shortest passageway around the combined bilges 98 of all four barrels 82, 84, 86, and 88. Elastic strap 70, under tension, serves as the means for gathering cover 92 at open end 94, forcing the inside of cover 92 against the outer surface of barrels 82, 84, 84, and 88 at open end 94. Open end 94 of cover 92 is maintained in limited contact against the outer surface of barrels 82, 84, 84, and 88 by the means for gathering.

[0080] FIG. 5A is a perspective view of a portion of foldable barrel pad 100 (if sized for a single barrel) or pallet pad 100 (if sized to cover the top surface of a pallet which may hold, for example, one, two, four, six, or eight barrels) for placement on a top surface of a pallet, with the barrels to be in upright position on top of barrel/pallet pad 100. Barrel/pallet pad 100 has base portion 102 which remains in contact with the top surface of the pallet and on top of which the barrel or barrels rest, and folding portions 104 which can be folded up along fold lines 106 illustrated for folded barrel/pallet pad 108 as illustrated in FIG. 5B.

Alternatively, although not illustrated, the barrel/pallet pad can comprise the base portion without any folding portions. In all embodiments utilizing a barrel or pallet pad, the pad acts as a cover over the bottom of the barrels to provide a high ethanol environment under the bottom of the barrels, and can also act as an absorbent to soak up liquid passing through barrels or condensing between the barrel and the cover.

[0081] FIG. 6A is a perspective view of a schematic of an alternative barrel- with-cover assembly 120 with barrel 20 having cover 122 thereover. Cover 122 has closed end 124, tubular portion 125, and open end 126, with the film from which cover 122 is made doubling back and affixed to itself (e.g., by heat sealing, adhesive, etc) to form casing 128 having therewithin a casing enclosure providing a confined domain within which is a loop of elastic strap 70 therein. Puckering of cover 122 at open end 126 is caused by open end 126 having an inside perimeter large enough to pass over barrel bilge 130, with elastic strap loop 70 contracting back towards its unstretched dimension and thereby providing a means for gathering cover 122 at open end 126 in barrel-with-cover assembly 120 of FIG. 6A. Open end 126 of cover 122 is maintained in limited contact with the outer surface of barrel 20 by the means for gathering.

[0082] Although the vertical position of the barrel 20 and cover 122 can be as illustrated in FIG. 6A, with open end 126 of cover being over top head 127 of barrel 20, during aging it may be preferred to flip barrel 20 upside down so that top head 127 of barrel 20 becomes bottom head 127 of barrel 20, to allow the passageway through open end 126 of cover 122 to allow fluid between barrel 20 and cover 122 to evaporate or otherwise escape from between cover 122 and barrel 20.

[0083] FIG. 6B is a perspective view of a schematic of an alternative barrel- with-cover assembly 140 with barrel 20 having first cover 122 thereover. First cover 122 is identical with first cover 122 of FIG. 6A, and therefore has closed end 124 and open end 126, with the film from which first cover 122 is made doubling back and affixed to itself (e.g., by heat sealing, adhesive, etc) to form casing 128 having therewithin a casing enclosure providing a confined domain within which is a loop of elastic strap 70 therein. First cover 122 is puckered at open end 126, as described for FIG. 6A. Open end 126 of first cover 122 is maintained in limited contact with the outer surface of barrel 20 by the means for gathering.

[0084] Barrel-with-cover assembly 140 further comprises second cover 142 thereover. Second cover 142 has closed end 144 that covers the top of barrel 20 and also overlaps a portion of first cover 122. Second cover 142 also has tubular portion 146 that further overlaps first cover 122 and which terminates in second open end 148, with the film from which second cover 142 is made being doubled back and affixed to itself (e.g., by heat sealing, adhesive, etc) to form casing 150 having therewithin a casing enclosure providing a confined domain within which is a tensioned elastic strap loop 70. Second cover 142 is puckered at open end 148 because elastic strap loop 70 maintains itself in higher tension than is second cover 142 at open end 148. In this manner, open end 148 of cover 142 is maintained in limited contact with the outer surface of barrel 20 by the means for gathering.

[0085] Although the vertical position of the barrel 20 and first cover 122 and second cover 142 may be as illustrated in FIG. 6A, with open end 126 of cover being over top head 127 of barrel 20, during aging it may be preferred to flip barrel 20 upside down so that closed end 144 of second cover 142 is beneath the bottom head of barrel 20, with the closed end of second cover being provided with a liquid exit port, to allow the passageway through open end 126 of cover 122 to allow fluid between barrel 20 and cover 122 to escape from between first and second covers 122 and 142, and barrel 20. [0086] FIG. 7 is a schematic longitudinal cross-sectional view of barrel-with- cover assembly 160 with barrel 20 having cover 162 thereover, with cover 162 having closed end 164 covering barrel top head 166 and open end 168 near the bottom end of the staves, with open end 168 of cover 162 being doubled back and sealed to itself to make casing 170 defining a casing enclosure, with elastic strap loop 70 under tension inside the enclosure formed by casing 170.

[0087] FIG. 8 is a schematic longitudinal cross-sectional view of barrel-with- cover assembly 180 with barrel 20 having first cover 162 over the barrel staves, second cover 172 covering barrel top head 174 and overlapping first cover 162, and third cover 182 covering barrel bottom head 184 and also overlapping first cover 162.

[0088] First cover 162 has first open end 163 the film being doubled back and sealed at seal 164 to make first casing 165 providing a first casing enclosure in which is first elastic strap loop 166 which is the means for gathering first cover 162 at first open end 163 whereby first cover 162 is in limited contact with barrel 20 at first open end 163. First cover 162 also has second open end 167 with the film again being doubled back and sealed at seal 168 to make second casing 169 providing a second casing enclosure in which is second elastic strap loop 170 which is the means for gathering first cover 162 at second open end 167 whereby first cover 162 is in limited contact with barrel 20 at second open end 167.

[0089] Second cover 172 has first closed end 173 covering barrel top head 174, with second cover extending down to third open end 175 at which the film is doubled back and sealed at seal 176 to make third casing 177 providing a third casing enclosure in which is third elastic strap loop 178 which is the means for gathering second cover 172 at third open end 175 whereby second cover 172 is in limited contact with barrel 20 at third open end 175. [0090] Third cover 182 has second closed end 183 covering barrel bottom head 184, with third cover extending down to fourth open end 185 at which the film is doubled back and sealed at seal 186 to make fourth casing 187 providing a fourth casing enclosure in which is fourth elastic strap loop188 which is the means for gathering third cover 182 at fourth open end 185 whereby third cover 182 is in limited contact with barrel 20 at fourth open end 185.
