摘要:
A method for producing a beverage from an infusible material such as coffee or tea by contacting the material with aqueous medium such as hot water in successive discrete portions, each successive portion re-suspending and re-agitating the material to increase extraction efficiency. The infusible material is preferably enclosed in a disposable brewing container such as a sachet or capsule, the aqueous medium injected therein in successive cycles.
