Devices and methods for extraction of a beverage from a beverage bottle, such as a wine bottle, using an extraction device. A clamp of the extraction device may include a container engagement surface arranged to disengage the clamp from the container neck when the clamp is pulled upwardly relative to the container neck. The container engagement surface may include a surface that slopes upwardly and outwardly relative to the container neck and that moves the clamp radially outwardly and away from the container neck as the clamp is moved vertically upwardly relative to the container neck.

A portable beverage dispensing system is disclosed. The portable beverage dispensing system includes a reservoir container with an internal volume for holding a beverage. The beverage dispensing system also includes a pressure unit accessory and a dispensing mechanism accessory that detachably and interchangeably attached to accessory attachments on the reservoir container that are in fluid communication with the internal volume of the reservoir container. The pressure unit accessory includes a pressure regulator and a removable gas canister for pressurizing the reservoir container and dispensing the beverage through the dispensing mechanism accessory.

A system for making a personalized malt-based beverage may comprise at least one packaged base liquid and at least one separately packaged flavor ingredient. The at least one packaged base liquid may comprise at least about 0.1% wt ethyl alcohol, at least about 3% wt malt extract solids, and a carbon dioxide level between about zero grams per liter and about 1.5 grams per liter. The separately packaged flavor ingredient may comprise a dry ingredient.

An adapter for an airtight connection to a container and for airtight dispensing of the container's contents, the adapter having: a gate valve, a tube extending from the gate valve to a female coupling, the female coupling being configured for insertion in a mouth of the container, the female coupling having a dispensing valve for opening when dispensing the container's contents and closing when dispensing is finished as needed, such that air is prevented from entering the container, and an airtight connector for connecting the adapter to the container.

The present invention is directed to a portable container for a beverage, such as beer, from a Sixth barrel or Cornelius keg. The portable container is specifically designed for storing, cooling, transporting and dispensing a beverage, such as beer. The portable container has a self-contained container of CO.sub.2, a regulator, and a tap for the keg.

A pressure regulating system for a beverage container includes a first compartment for containing a pressurized gas. The first compartment is in fluid communication with a surrounding space through a gas valve for opening and closing a passage between the first compartment and surrounding space. A gas valve control system includes a deformable and/or movable wall or wall part, which is in contact with the gas valve for opening and/or closing the gas valve. A second compartment is provided at a side of the deformable and/or movable wall part. The movable and/or deformable wall part forms a wall of said second compartment and the second compartment forms a pressure regulating space and includes a wall part formed by or including at least a gas permeable, liquid tight permeable wall part.

A receptacle for storing, pressurizing, and dispensing packaged beverages. The receptacle includes an airtight chamber with a removable lid, wherein the joint between the lid and the chamber is also airtight. A gas valve allows for the inflow and outflow of gas, and a tap port and tap stem allow the beverage to be dispensed without breaking the seal of the chamber. A pressure relief valve allows for more rapid depressurization. The chamber can be used at high and low pressures, such as a partial vacuum, to prevent oxidation of a number of open beverages, such as beers, wines, and sodas. A pressure gauge port coupled with an optional pressure gauge allows a user to verify the appropriate pressure for the type of beverage being preserved. The gas valve may be disposed on a base of the receptacle, as may the pressure relief and/or the pressure gauge port.

A system and method for dispensing beverage from a container, such as wine from a wine bottle. An identification element may be secured to a beverage container and include a tag and optically readable code that uniquely identify the container. A dispenser may dispense beverage from a container, and be able to read the tag of the identification element. Information regarding characteristics of beverage in the beverage container may be associated with a corresponding identification element and include a brand, type, vintage or volume of beverage in the container.

A beverage dispenser with a variable pressure regulator cap assembly that includes a high pressure cavity defined by a cap body. The high pressure cavity receives pressurized gas from a compressed gas reservoir. A low pressure cavity is connected to the high pressure cavity via a high pressure gas passageway. The low pressure cavity defines a low pressure gas passageway that penetrates the cap body. A piston seat is positioned on a high pressure cavity side of the high pressure gas passageway. A piston regulates introduction of the pressurized gas into the high pressure gas passageway. A diaphragm is positioned between an ambient pressure cavity and the low pressure cavity and translates the piston relative to the piston seat. A main spring is positioned between a diaphragm and a spring hat. Rotation of the drive screw translates the spring hat to affect compression of the main spring against the diaphragm.
