Definitions

  • This invention is generally directed to methods and 5 apparatuses for dispensing beverages and particularly to methods and apparatuses for improving the shelf life of opened bottles or other containers of wines and other beverages.
  • the apparatuses include enclosures in which 10 opened bottles or other opened containers of beverages are housed so that the contents thereof may be subjected to an environment of high pressure inert gas such as nitrogen while the interior of the enclosures are simultaneously being vented to atmosphere. Thereafter, the pressure may .15 be selectively reduced for 'subsequent ' product dispensing at initial dispensing pressures of up to approximately 15 p.s.i.g.

  • a beverage such as wine may be selectively aged and then preserved at its peak utilizing an apparatus of the invention.
  • UBSTITUTESHEET beverages and particularly wines in order to facilitate consumer service and decrease product waste.
  • a major dir ⁇ ection of these efforts has been " to increase the shelf life of various opened containers of beverages.
  • Prolonging shelf- life is particularly advantageous for the dispensing of products which are normally stored in containers wherein the volume of product is greater than the amount of product which is likely to be utilized or consumed at one time.
  • a prolonged shelf life is particularly beneficial if it is possible to preserve the original quality and palat- ability of the product.
  • SUBSTITUTE SHEET promote oxidation of the alcohol within the wine.
  • inert gases In utilizing inert gases to preserve the life of opened containers of beverages, the containers are initially opened and exposed to atmosphere and thereafter, a plug is inserted to seal the contents. Inert gas such as nitrogen is sub ⁇ sequently introduced into the container and serves to pro ⁇ vide pressure for dispensing the fluid therein and at the same time provides a nitrogen-enriched environment above the fluid.
  • Inert gas such as nitrogen is sub ⁇ sequently introduced into the container and serves to pro ⁇ vide pressure for dispensing the fluid therein and at the same time provides a nitrogen-enriched environment above the fluid.
  • Unfortunately as most wines and other beverages are stored in glass containers, the amount of pressure which can be applied within the container is very limited. Because of this, operating pressures of up to 5 p.s.i. are generally not exceeded, not possible or not practical for use in present wine preserving and dispensing systems.
  • the plugs or valves which are used to seal con ⁇ tainers prior to pressurization often leak, come loose or pop free from engagement- with the containers thereby re ⁇ leasing the inert gas and admitting various amounts of air so that. further aging is allowed to proceed. As the wine is exposed to more oxygen, oxidation will continue until the wine spoils. Generally, it has not been possible to preserve the shelf life of wines more than several weeks without the wine beginning to spoil.
  • This invention is directed to methods and apparatuses for preserving and dispensing beverages and particularly wines from bottles or other normally sealed containers wherein an opened container of beverage is placed within a sealed enclosure and thereafter subjected to an envir- onment of high pressure inert gas at pressures in excess of approximately 20 p.s.i.g. (gauge) and wherein the pressure within the container is simultaneously balanced with the pressure within the enclosure so that failure of the container due to increased pressure is prevented. As the inert gas is being introduced, the container is vented
  • the pressure of inert gas may thereafter be selectively reduced to a lower initial dispensing pressure in the range of approximately 15 p.s.i.g. or less and the beverage stored at the lower pressure for future dispensing.
  • the enclosure is of a size to receive the bev ⁇ erage container completely therein and includes a cover to seal the enclosed container from the surrounding environ ⁇ ment. Valves are provided to permit the inlet of gases in- eluding inert nitrogen into both the enclosure and beverage container and to permit the exhaustion or purging of gases therefrom once a predetermined pressure is achieved.
  • Conduits are also provided to dispense the beverage con ⁇ tents of the container either directly from the enclosure or through secondary dispensing units such as conventional refrigerated dispensers.
  • oxygen may be selectively supplied to the enclosures to promote the aging of wines which have not yet reached their peak.
  • SUBSTITUTESHEET supplemental enclosure and therein subjected to pressures of inert gases which would normally rupture or destroy the beverage container and which act to preserve the overall shelf life of the beverage by enabling oxygen to be removed from the beverage environment.
  • Another object of the present invention is to provide a dispensing system for beverages such as wines and the like wherein high pressure inert gas is used to initially vent or expel oxygen from the dispensing enclosure so that subsequent oxidation or aging of the wine is prevented even when dispensing pressures created by the inert gases with the dispensing enclosure drop to zero or atmospheric pressure.
  • a further object of the present invention is to pro- vide an enclosure for housing opened bottles of wine for future dispensing wherein the contents thereof may be systematically aged by the selective introduction of an oxygen gas into either the wine bottle or container to thereby promote the aging of the wine and wherein further aging can be halted by exposing the wine to high pressure inert gas while purging air and oxygen within the envir ⁇ onment surrounding the wine to thereby prevent further oxidation thereof.

  • the contain ⁇ ers or enclosures of the present invention are shown as being specifically used to house opened bottles of wine or similar beverage so that the contents thereof may be re ⁇ tained at their peak, palatable and consumer acceptable condition. It is well known that exposure of beverages to air, such as when a bottled wine has been opened, results in the contents rapidly oxidizing until a point where spoilage occurs.
  • the dispensing enclosures of the present invention have, been designed to extend the life of opened bottles or containers of wine and other beverages and food products for unlimited periods utilizing the methods as will be hereinafter.described in detail.
  • SUBSTITUTE SHEET The primary consideration in extending the useful or shelf lives of comestible consumer products including wines and other alcoholic-beverages is to-provide a low cost method of preventing the continued oxidizing process which leads to spoilage and unpalatability of such products.
  • the interiors of the enclosures which house the wine bottles are also placed under the same pressure so that the pressures interiorly and exteriorly of the bottled wines are balanced thereby preventing the possibility of the bottles failing or exploding under pressure.
  • the wines .are being pressurized to approxi- mately 20 p.s.i.g. and preferrably between 20 to 30 p.s.i.g., the air or oxygen within the bottles and enclos ⁇ ures is vented to atmosphere.
  • the pressure level may thereafter be permitted to drop or is decreased to lower dispensing pressures, which may.be in the range of approx- imately 5 to 15 p.s.i.g. dependent upon an enclosure's volume or capcity.
  • the storage pressures are retained at approximately 10 p.s.i.g. until a product is initially dispensed and thereafter the pressure will decrease as the product level drops.
  • the initial high pressure treat- ment of the contents of opened containers or bottles of wine actually functions to drive even the slightest remain ⁇ ing oxygen from solution, thereby preventing further oxida ⁇ tion of the wine.
  • the wine can be maintained in an inert atmosphere over long periods of time at lower pressures with further aging or oxidation eliminated.
  • a Royal OPORTO, 1970 vintage Portuguese Port was- opened and exposed to atmosphere and tasted on June 19, _1985. After tasting, the opened bottle was placed into an enclosure of the type generally shown in Fig. 4 of the drawings. The enclosure surrounding the bottle was sealed and thereafter inert nitrogen gas was introduced therein.
  • a valve on the enclosure opened permitting the air therein to be vented to atmosphere.
  • the pressure was continuously raised to approximately 25 p.s.i.g. and then permitted to slowly decrease.
  • the pressure was finally lowered to approximately 10 p.s.i.g. and the product placed in storage.
  • the product has been periodically tasted by dispensing a portion thereof utilizing a pressure reducing dispensing valve mounted to the container.
  • the wine remains at its peak flavor and totally palatable and fit for consumer consumption. No noticeable deterioration in the product has taken place.
  • a second test was made on an opened bottle of a Gammay Beaujolois, vintage 1980, wherein the opened container or
  • SUBSTITUTE SHEET bottle was also placed in a dispenser enclosure similar to that shown in Fig. 4 of the drawings.
  • a nitrogen gas was used to drive off the air and raise the pressure within the enclosure and bottle to between 20 to 25 p.s.i.g. Again, the enclosure was vented to atmosphere when the pressure reached approximately 15 p.s.i.g. Thereafter, the pressure was reduced to an initial dispensing pressure of approxi ⁇ mately 8 to 10 p.s.i.g.
  • the wine bottle was removed from the enclosure and the wine tasted. The wine was found to have remained at its peak flavor and taste and, again, the wine appeared to be as good and as consumable as it was when originally opened.
  • the enclosure used in the second example was then used on July 30, 1985 to house a bottle of La Tache 1957, bottle No. 15198 which had been opened and had begun to turn cloudy.
  • Inert nitrogen was added and the gas pressure was raised as discussed with respect to the previous examples to approximately 25 p.s.i.g. while the oxygen was vented and then the pressure reduced to approximately 10 p.s.i.g.
  • the wine had not deterior ⁇ ated or spoiled further than it had on July 30th.
  • a fourth test was made using an" opened bottle of Kistler Sauvinoin-Blanc 1982.
  • the wine was placed within an enclosure similar to those of the preceding examples and thereafter the inert nitrogen added to pressurize the wine to 20 to 25 p.s.i.g. while the air and oxygen was vented from the enclosure. The pressure was then reduced to 10 p.s.i.g.
  • the wine was originally treated on June 18, 1985 and was dispensed for consumer taste testing on July 31, 1985. The wine remained of excellent consumer quality and taste.
  • SUBSTITUTESHEET although the examples reflect initial storage pressures in the range of 8 to 10 p.s.i.g., it is believed that press ⁇ ures ranging from 0 to 15 p.s.i.g. could be suitable under some conditions. Inthis regard, it should be noted that the initial storage pressure is also the initial dispensing pressure. Also, such pressures could be as high as the highest pressure achieved during the introduction of the inert gas. The pressure is preferrably lowered for storage and dispensing as pressures in excess of 15 p.s.i.g. are generally not necessary.
  • the initial dispensing pressure need only be high enough to insure that the entire contents of the bottle can be dispensed.
  • the pressure will continue to decrease as the wine is dispensed, the wine remaining will be preserved in the inert gas environment even though the pressure may drop to zero p.s.i.g. (i.e. atmospheric pressure) as substantially all oxygen was originally purged from the environment thereby preventing further oxidation of the wine.
