Title: Apparatus and method for making a beverage

Abstract: An improved beverage infusion device and a method of rapid brewing an infusible beverage substance such as fresh, fine ground, roasted coffee by air agitation in an air-water chamber. The wall of the chamber is constructed of a fine porous filtering material that confines particles of coffee during agitation thereof with water of an amount necessary for brewing either one or more serving portions of coffee. An air conduit directs air underneath the coffee particles accumulated in the air-water chamber that is immersed in hot water. The hot water enters the porous wall of the air-water chamber, saturating the coffee particles. One or more intermittent burst of air are directed by the conduit under the coffee particles thereby momentarily suspending the coffee particles in the water, and agitating the coffee particles and the water. The water solubles of the coffee are extracted rapidly and mixed with the water to create a beverage.
