Abstract: A method of making a pressurized packaged liquid beverage including filling a container including a one-way valve with a liquid mixture including a base liquid and a gum; sealing the container; introducing a volume of gas through the one-way valve after sealing the container; and agitating the container. When the container is opened, the liquid mixture increases in volume and separates into a liquid phase and a drinkable foam phase, which may persist for an extended period of time. The base liquid includes milk, coffee, fruit juice, or mixtures thereof.

Abstract: A method of making a pressurized packaged liquid beverage. The method includes filling a container including a one-way valve with a liquid beverage, sealing the container, introducing a volume of gas through the one-way valve after sealing the container, and agitating the liquid beverage inside the sealed container, When the container is opened, the liquid beverage increases in volume and separates into liquid phase and a drinkable foam phase. The method may be carried out in a sealed container including a one-way valve adapted to allow a gas to enter the first container but not exit or a circulatory agitation system according to other embodiments. Thee liquid beverage may include milk, coffee, fruit juice, or mixtures thereof, particularly mixtures of milk and coffee, and may further include a gum. The gas may be nitrous oxide.

Abstract: A process for packaging pressurized beverages. The process includes mixing liquid, a solute that depresses the freezing point of the liquid, and gas. Next, the liquid-gas mixture is allowed to rest. Then, retail containers are filled with the mixture. During the mixing and filling steps of the process, the liquid-gas mixture is subjected to pressures that are higher than atmospheric pressure. Unfortunately, such pressure cannot be maintained when the container is transferred from the filling station to the sealing station causing dissolved gas to leave the liquid and foam to overflow the container during the transfer. To prevent such an overflow, prior to the transfer, the dissolved gas is put to sleep by reducing the temperature of the liquid to below 0° C. (32° F.) and optionally allowing the liquid-gas mixture to rest. The liquid beverage may include milk, coffee, tea, fruit juice, chocolate or mixtures thereof, and may include a gum.

Abstract: A device for brewing coffee including a jacketed brewing vessel and a manual siphon element and methods of using the device to brew coffee. The device includes a base having a bowl, a first neck communicatively connected to the bowl, and a second neck communicatively connected to the bowl; a brewing vessel communicatively connected to the first neck; and a siphon element communicatively connected to the second neck. Operating the siphon element results in a reduced pressure within the bowl. When the brewing vessel is full of a first volume of water, the reduced pressure within the bowl results in the volume of water flowing from the brewing vessel into the bowl. A second volume of water may be added to a jacket of the brewing vessel to change the temperature of the first volume of water.
