ABSTRACT:
An apparatus for brewing beverages in portions, especially espresso coffee, comprises means (9-12) for dispensing ground coffee beans (14) to a coffee receiving means (1) as well as water feeding means (22, 42-45) for passing hot water through the coffee in the coffee receiving means (1) and further to a cup (48). The coffee receiving means (1) comprises a sleeve-shaped body (3) made of a resilient material, said body on the outside being supported by a substantially rigid supporting means (4) and on the inside between the ends being of a volume exceeding the measured amount of coffee powder (14). The water feeding means (22, 42-45) comprises a piston device (22), which during the feeding of water is adapted to simultaneously compress both the measured amount of coffee (14) and the sleeve-shaped body (3) in its axial direction, while the amount of coffee (14) and the sleeve-shaped body (3) at the opposite axial end are supported by a sieving means (17, 18) allowing passage of the brewed hot beverage.
