摘要： A method for preparing cold coffee involves placing ground coffee in a maceration basket, which is mounted in a maceration tank, and subjected the coffee to maceration by recirculated flow of maceration fluid pumped under pressure by a circulating pump to a hydrating head mounted centrally to the maceration basket. Preferably the maceration basket is completely immersed in the maceration fluid.
A device for preparing cold coffee is also disclosed, the device has a maceration tank, in which a maceration basket 1 for ground coffee is operationally mounted. The maceration basket is formed as a cylinder having a hollow center column dimensioned to receive at least a portion of the hydrating head. A circulating pump circulates the maceration fluid under pressure, from the maceration tank, via the hydrating head and the ground coffee batch disposed in the maceration basket back into the maceration tank.
