ABSTRACT:
A beverage infusion device for preparing a beverage such as coffee includes a gas-liquid chamber permeable to air and water which contains an infusible, insoluble dry beverage substance containing edible, soluble food solids, such as coffee particles, and a carbon dioxide source which releases carbon dioxide when immersed in liquid, such as water. When the infusion device is immersed in water, the carbon dioxide source, preferably situated beneath the coffee particles, releases carbon dioxide. The carbon dioxide bubbles up through the coffee particles, momentarily suspending and agitating the coffee particles. Maximum contact between water and coffee particles is achieved and the edible, soluble food solids are quickly extracted from the coffee particles to form a hot beverage.
Also disclosed is a beverage infusion device including a percolator within a gas-liquid chamber permeable to air and water containing an indusible, insoluble dry beverage substance such as coffee particles. When the beverage infustion device is repeatedly immersed in and removed from water, water enters into the gas-liquid chamber through the percolator at a point above the coffee particles, drains over and through the coffee particles and out of the gas-liquid chamber. A disposable, miniature percolator for brewing a single cup or limited number of cups of a hot beverage such as coffee is thus provided.
