Description

ADDITION OF TRANSITION METAL TO WINES AND WINE TYPE BEVERAGES IN METALLIC BEVERAGE CONTAINERS TO PREVENT UNWANTED AROMAS

FIELD OF INVENTION

This invention relates to a method for removing malodors and/or unwanted-flavors from a wine and/or wine-type beverage using a transition metal, and more particularly to the removal of unwanted or malodorous sulfur and/or sulfur-containing compounds from wine and/or wine-type beverages by adding copper and/or a copper-containing compound during bottling of the wine and/or wine type beverage.

BACKGROUND OF THE INVENTION

Wine making typically includes pressing fruit (typically, grapes) to obtain a fruit juice, fermenting the fruit juice, maturing the fruit juice to form wine and, after maturation, bottling the wine. Typically, the fermentation and maturation processes are carefully controlled to develop preferred organoleptic characteristics. However, due to the characteristics of the fruit (such as, growing, harvesting and/or storage conditions), maturation process (such as, temperature, oxidation, and such), and/or bottling (such as, oxygen, wine composition, container and closure system) unwanted odors and/or flavors can develop during one or both of the fermentation and maturation processes. The unwanted odors and/or flavors are typically removed by treating the wine with a fining agent. The fining agent is usually separated from the wine prior to bottling the wine. Examples of fining agents include isinglasse, bentonite, galatin, casein, carrageenan, alginate, diatomaceous earth, pectinase, pectolase, polycar, colloidal silica, copper sulfate, albumen, hydrated yeast, activated carbon, and potassium caseinate. The unwanted odor and/or flavor are typically associated with sulfur and/or sulfur-containing compounds. The sulfur and/or sulfur-containing compounds may be present in the fruit juice that wine is prepared from, may develop during fermentation and/or maturation, and/or may develop as the wine and/or wine-type ages during storage. In some instances, the generation of sulfur and/or sulfur-containing compounds can be minimized, or substantially eliminated, by storing and/or aging the wine in a container having a cork, which typically permits the ingress of oxygen. Oxygen can prevent, or at less minimize, the formation of sulfur and/or sulfur-containing compounds.

However, unwanted odors and/or flavors can develop in bottled wine (such as, wines bottled in containers having a non-cork closure system). Unwanted odor and flavor development is particularly problematic in wines bottled in metallic containers, even more particularly to wines bottled in metallic containers having metallic lids and/or closure systems. Since it is more cost effective to manufacture, fill and transport containers made from metallic materials as opposed to traditional glass, there is a significant need in the beverage and container industries to manufacture and utilize metallic containers for wine and other alcoholic beverages, yet reduce the unwanted odor and flavor caused by sulfur and/or other sulfur-containing compounds.

Thus, a significant need exists for a bottling process that reduces unwanted odor and/or flavor formation in wines bottled in metallic containers, particularly for wines bottled in metallic containers having metallic lids and/or closure systems.

SUMMARY OF THE INVENTION

This disclosure relates to a container system for reducing and/or eliminating unwanted odor and flavor in bottled wine and to a method for forming the container system for reducing and/or eliminating unwanted odor and/or flavor in bottled wine. More specifically, this disclosure relates to a metallic container system and to a system for reducing and/or eliminating unwanted odor and/or flavor in bottled wine and wine-like beverages.

One aspect of the present invention is a metallic container adapted to store a wine product, comprising: a metallic side wall having a metallic bottom on a lower end and a neck on an upper end, the neck adapted to receive a closure system; and a transition metal, wherein the transition metal is provided as a compound in the metallic container and reacts with the wine product in the container to inhibit the formation of unwanted odors and/or flavors, and wherein the metallic container comprises no more than about 0.2 ppm of the transition metal.

The reaction between the wine product and the transition metal compound generally occurs after one or both of the fermentation and maturation processes. The wine product may further include one or both of a non- fermented fruit juice and soda water.

The metallic container may comprise aluminum. The metallic container has a predetermined volume. The predetermined volume being defined by a container wall interconnected to a container bottom and a metallic closure system. The closure system is preferably a lid or screw cap. The container bottom and closure system are preferably in an opposing relationship.

Preferably, the transition metal is copper.

In such embodiments, reacting the wine product with the transition metal-containing metallic container and/or closure system forms a treated wine product. Furthermore, in some embodiments, reacting the wine product with the transition metal-containing metallic container and/or closure system releases at least some transition metal in the wine product to form the treated wine product. Moreover, in some embodiments, reacting the wine product with the transition metal-containing metallic container and/or closure system removes one or both of unwanted odor and flavor from the wine product to form the treated wine product.

Preferably, the container is an aluminum container having a predetermined volume for receiving the wine. A container bottom, wall and end closure define the predetermined volume. The container wall and bottom may be formed simultaneously by a draw/redraw process or may be formed from two distinct components. Furthermore, the container wall defines an aperture adapted to receive the metallic closure system. More preferably, the metallic container and the metallic closure system are substantially impervious to one or both of oxygen permeation and transmission.

The transition metal-containing compound contains a transition metal selected from the group of metals consisting of scandium, titanium, manganese, iron, cobalt, nickel, copper, zinc, yttrium, zirconium, niobium, molybdenum, ruthenium, rhodium, palladium, silver, hafnium, tantalum, tungsten, rhenium, iridium, platinum, and gold. Preferably, the transition metal-containing compound comprises copper.

While not wanting to be bound by theory, the contacting of the transition metal-containing compound with one or both of sulfur and a sulfur-containing compound forms an insoluble compound. The insoluble compound is believed to contain the transition metal and the one or both of the sulfur and sulfur-containing compound.

Typically, the sulfur and/or sulfur-containing compound is preferably are one of sulfide (S2‘), hydrogen sulfide (HS'), dihydrogen sulfide (H2S), mercaptan (R-SH), 3-mercaptohexanol (CH3CH2CH(SH)CH2CH20H), methyl mercaptan, and/or a mixture thereof. Commonly, the insoluble compound contains the transition metal and at least one of sulfide (S2‘), hydrogen sulfide (HS'), dihydrogen sulfide (H2S), mercaptan (R-SH), 3-mercaptohexanol (CH3CH2CH(SH)CH2CH20H), methyl mercaptan (CH3SH), ethyl mercaptan (CH3CH2SH), 2-mercatoethanol (HOCH2CH2SH) or a combination thereof.

Preferably, the transition metal is copper. The copper preferably forms an insoluble compound with the sulfur and/or sulfur-containing compound. Commonly, the insoluble compound contains copper (11) and at least one of sulfide (S2'), hydrogen sulfide (HS'), dihydrogen sulfide (H2S), mercaptan (R-SH), 3-mercaptohexanol (CH3CH2CH(SH)CH2CH2OH), methyl mercaptan (CH3SH), ethyl mercaptan (CH3CH2SH), 2-mercatoethanol (HOCH2CH2SH) or a combination thereof.

In a preferred embodiment, the treated and/or transition metal-containing wine product contains no more than about 0.2 ppm copper. In a more preferred embodiment, the treated wine contains copper in the form of copper (II). In an even more preferred embodiment, the treated wine product contains copper in the form of copper sulfate.

Another aspect of the present invention is a method for reducing unwanted odor in a wine-type beverage by contacting the wine-type beverage with a copper-containing material to form a treated wine-type beverage. The contacting of the wine-type beverage with the copper-containing material forms a treated wine-type beverage, and sealing the treated wine-type beverage in a container to form a bottled beverage. The container is sealed with an end closure. Preferably, the container comprises one of an aluminum container or glass container. The container has a predetermined volume, the predetermine volume defined by a container wall and a container bottom. The container wall defines a neck on an upper end to receive the end closure.

Some embodiments include filling the predetermined volume substantially with the treated wine-type beverage, and sealing the end closure to neck of the container to form the bottled beverage. Preferably, the container is substantially impervious to one or both of oxygen permeation and transmission. The end closure is at least one of a screw cap, a cork and a pull tab.

Preferably, the copper-containing material forms an insoluble copper-containing compound with sulfur or a sulfur-containing compound. The sulfur and/or sulfur-containing compound comprise one or more of sulfide (S2‘), hydrogen sulfide (HS'), dihydrogen sulfide (H2S), mercaptan (R-SH), 3-mercaptohexanol (CH3CH2CH(SH)CH2CH2OH), methyl mercaptan (CH3SH), ethyl mercaptan (CH3CH2SH), 2-mercatoethanol (HOCH2CH2SH) or a combination thereof.

The wine may or may not contain unwanted malodorous sulfur-containing compounds. Commonly, the wine is treated with one or both of a fining agent and a sulfur removal agent prior to step 110 to remove the unwanted malodorous sulfur-containing compounds. One or both of the fining and sulfur removal agents typically remove at least most, if not all, of the unwanted malodorous sulfur-containing compounds present in the wine. Furthermore, the fining and/or sulfur removal agents commonly remove the unwanted malodorous sulfur-containing compounds by one or more of absorption, adsorption, complexation, precipitation, and chemical reaction of the fining and/or sulfur removal agents with the unwanted malodorous sulfur-containing compounds. Ordinarily, one or more of the absorbed, adsorbed, complexed, precipitated and/or reacted unwanted malodorous sulfur-containing compounds, the fining agent and sulfur removal agent are removed from the wine prior to step 110.

The transition metal content of the aluminum alloy is typically from about 0.01 to about 5 wt%, more typically from about 0.05 to about 4.5 wt%. In some configurations the transition metal content of aluminum alloy is from about 2 to about 4.5 wt%, preferably from about 2 to about 3 wt%. In some configurations, the transition metal content of the aluminum alloy is as low as from about 0.05 to about 1.5 wt%.

In some configurations, the copper content of the aluminum alloy is from about 0.01 to about 0.2 wt% copper. In some configurations, the copper content of the aluminum alloy is from 0.05 to about 0.03 wt% copper.

In some embodiments, the metallic lid and/or metallic closure system comprise a second metallic alloy.

In some configurations, the first and second alloys are the same. In some configurations, the first and second alloys differ.

While not wanting to be limited by example, the aluminum alloy typically comprises one of 1000 or 3000 aluminum alloy. Non-limiting examples of 1000 series aluminum alloys are 1050, 1060, 1100 and 1199. The 1000 series aluminum alloys typically contain from about 99 to about 99.99 wt% aluminum. Moreover, the 1000 series aluminum alloys typically contain one or more of Si, Fe, Cu, Mn, Mg, Cr, Zn, V, Ti, Bi, Ga, Pb and Zr.

According to some embodiments, the copper-containing compound comprises one of copper sulfate, copper benzoate, or a mixture thereof.

Preferably, the copper-containing compound is hydrated copper sulfate. The hydrated copper sulfate may have any degree of hydration. Commonly, the hydrated form of copper sulfate may contain for each mole of copper no more than one mole of water, more commonly no more than two moles of water, even more commonly no more than three moles of water, yet even more commonly no more than four moles of water, still yet even more commonly no more than five moles of water, still yet even more commonly no more than six moles of water, still yet even more commonly no more than seven moles of water, still yet even more commonly no more than eight moles of water, still yet even more commonly no more than nine moles of water, still yet even more commonly no more than ten moles of water, still yet even more commonly no more than eleven moles of water, or still yet even more commonly no more than twelve moles of water.

In some embodiments, the copper sulfate commonly contains for each mole of copper from about 1 to about 12 moles of water, more commonly from about 3 to about 10 moles of water, even more commonly form about 4 to about 6 moles of water, or yet even more commonly about 5 moles of water.

In some embodiments, the copper-containing compound is provided in an anhydrous form. In some configurations, the copper sulfate is provided in an anhydrous form.

The contacting of the copper-containing compound with the wine forms a treated wine. The treated wine may comprise the copper-containing compound in a substantially dissolved, dissociated state in the treated wine. Commonly, the treated wine contains no more than about 0.5 ppm of the copper-containing compound, more commonly no more than about 0.4 ppm of the copper-containing compound, even more commonly no more than about 0.35 ppm of the copper-containing compound, yet even more commonly no more than about 0.3 ppm of the copper-containing compound, still yet even more commonly no more than about 0.25 ppm of the copper-containing compound, still yet even more commonly no more than about 0.2 ppm of the copper-containing compound, still yet even more commonly no more than about 0.15 ppm of the copper-containing compound, still yet even more commonly no more than about 0.1 ppm of the copper-containing compound, still yet even more commonly no more than about 0.05 ppm of the copper-containing compound, still yet even more commonly no more than about 0. 025 ppm of the copper-containing compound, still yet even more commonly no more than about 0.01 ppm of the copper-containing compound, or still yet even more commonly no more than about 0.005 ppm of the copper-containing compound.

Preferably, the treated wine contains no more than about 0.2 ppm of copper. More preferably, the treated wine contains about 0.2 ppm of copper. Typically, treated wines having no more than about 0.2 ppm copper are less corrosive to aluminum containers than treated wines having more than about 0.2 ppm copper. More typically, treated wines having about 0.2 ppm are less corrosive to the aluminum container than treated wines having more than 0.2 ppm copper.

The transition metal compound may be in a powder form or in the form of a solution. Preferably, the transition metal compound is provided in a powder form. More preferably, the transition metal powder is provided in the form of a flowable powder. The flowable powder may comprise the transition metal compound in the form of fine particulate. The flowable powder is in a form a fine particulate powder that can be dosed by a solids handling and/or dosing equipment.

In some embodiments, the transition metal solution is provided as an aqueous or wine solution containing the transition metal compound. The aqueous or wine solution is in a form that can be dosed by solution dosing and/or metering equipment.

In step 130, a container 200 (see Figs. 2A, 2B, 3 A and 3B) is charged with the wine. The container 200 can be any container suitable for storing the wine. The container may comprise a polymeric material, a ceramic material, a glass, a metallic material or a combination thereof. The container 200 is substantially impervious to one or both of oxygen permeation and transmission. The container 200 has a predetermined volume 240, defined by a container wall 250 interconnected to a container bottom 270. Furthermore, the wall defines an aperture 300. The predetermined volume 240 is configured to receive the wine. Moreover, the aperture 300 is adapted to receive a metallic closure system 210. Typically, the wine is charged to the container 200 through the aperture 300. Moreover, the charging of the wine to the container 200 substantially, but not completely, fills the predetermined volume 240 with the wine.

In some embodiments, the container 200 is a metallic container. The container 200 preferably comprises an aluminum container. The container wall 250 and bottom 270 respectively have interior wall 260 and bottom 280 surfaces and exterior wall 250 and bottom 290 surfaces. The wine contained in the predetermined volume 240 is in contact with the interior wall 260 and bottom 280 surfaces.

In some embodiments, the one or both of the interior wall 260 and bottom 280 surfaces comprise aluminum. In such embodiments, the wine contained within the predetermined volume 240 is in contact with the interior 260 and bottom 280 surfaces comprising aluminum.

In some embodiments, one or both of the wall interior 260 and exterior 250 surfaces have a polymeric coating. Moreover, in some embodiments, one or both of the bottom interior 280 and exterior 290 surfaces have a polymeric coating. In such instances, the wine contained within the predetermined volume 240 is contact with the polymeric coating on one or more of the wall interior 260 and bottom interior 280 surfaces.

Returning to steps 120 and 130, in some configurations, the transition metal compound is contacted with the wine prior to filling the container 200. In other configurations, the container 200 is charged with one of the wine and transition metal compound prior to charging the container 200 with the other of the wine and transition metal compound. In yet other configurations, the wine and the transition metal compound are charged to the container 200 at about the same time by separate and/or combined wine charging and transition metal charging processes.

In step 140, the container 200 is sealed. Typically, the sealing of the container includes interconnecting and mechanically joining a metallic closure system 300 about the aperture 300. Wines sealed in containers for storage (such as, wines sealed in corked containers) are typically sealed in containers that permit some degree of oxygen permeation and transmission, allowing at least some oxygen to enter the predetermined volume 240 during storage. In some configurations, the sealed container 200 is substantially impervious to one or both of oxygen permeation and transmission.

Those of ordinary skill in the art are aware that storing wine in a sealed container that is substantially impervious to oxygen permeation and transmission can lead to the formation of unwanted odors and/or flavors in the stored wine. Typically, the unwanted odor and/or flavor are due to the formation of one or more sulfur compounds. Non-limiting examples of the unwanted odor and/or flavor sulfur compounds are sulfide (S2‘), hydrogen sulfide (HS'), dihydrogen sulfide (H2S), mercaptan (R-SH), 3-mercaptohexanol (CH3CH2CH(SH)CH2CH2OH), methyl mercaptan (CH3SH), ethyl mercaptan (CH3CH2SH), 2-mercatoethanol (HOCH2CH2SH) or a combination thereof.

Transition metal compounds, particularly copper-containing compounds, can substantially remove the malodor and/or off-flavor from wine associated with one or more of sulfide (S2‘), hydrogen sulfide (HS'), dihydrogen sulfide (H2S), mercaptan (R-SH), 3-mercaptohexanol (CH3CH2CH(SH)CH2CH20H), methyl mercaptan (CH3SH), ethyl mercaptan (CH3CH2SH), 2-mercatoethanol (HOCH2CH2SH) or a combination thereof Generally, transition metals form insoluble compounds with sulfides and mercaptans.

While not wanting to be limited by theory, it is believed that the copper forms substantially insoluble sulfur-containing copper compounds with one or more of sulfide (S2‘), hydrogen sulfide (HS'), dihydrogen sulfide (H2S), mercaptan (R-SH), 3-mercaptohexanol (CH3CH2CH(SH)CH2CH2OH), methyl mercaptan (CH3SH), ethyl mercaptan (CH3CH2SH), 2-mercatoethanol (HOCH2CH2SH) or a combination thereof The formation of the substantially insoluble sulfur-containing copper compound (depicted as optional step 150) substantially removes the unwanted odor and/or flavor from the wine.

Generally, wines are substantially less likely to develop unwanted odor and/or flavor when stored in sealed containers having some degree of oxygen permeation and transmission. However, the method of process 100 could benefit wines that are susceptible to the development of unwanted odor and/or flavor development when stored in containers having insufficient oxygen permeation and transmission. Moreover, the method of process 100 could benefit wines stored in containers substantially lacking oxygen permeation and transmission, such as wines stored in metallic containers.

Preferably, the closure system 300 comprises a metallic lid and/or metallic closure system, more preferably an aluminum closure system. In some configurations, the metallic lid and/or metallic closure system is substantially impervious to one or both of oxygen permeation and transmission. The metallic lid and/or closure system may or may not comprise a polymeric coating.

Preferably, the metallic lid and/or closure system lacks a polymer coating positioned between the predetermined volume 240 and closure system 300. More preferably, the metallic lid and/or closure system comprises a copper alloy, even more preferably one of 1000 or 3000 aluminum alloy.

In some configurations, the closure system comprises a breathable metallic lid and/or closure system. The breathable metallic lid and/or closure system allows for at least some oxygen transmission. Preferably, the breathable metallic lid and/or closure system has oxygen transmission properties similar to cork closure system. The breathable metallic lid and/or closure system transmits sufficient oxygen to the bottled wine to substantially mitigate the aerobic conditions. Preferably, the breathable metallic lid and/or closure system transmits sufficient oxygen to the bottled wine to substantially mitigate the formation of sulfur and/or sulfur-containing compounds. In such instances, the wine is treated with little, if any, transition metal.

In some embodiments, the end closure of the metallic container is configured to accept a cork sealing system. The metallic container having a cork sealing system can have sufficient oxygen transmission to substantially mitigate of the bottled wine. In such instances, the wine is treated with little, if any, transition metal. A number of variations and modifications of the invention can be used. It would be possible to provide for some features of the invention without providing others.
