Abstract: Brewing unit of a beverage preparation machine with a brewing chamber (10) and a brewing chamber surface (15), wherein the brewing chamber (10) is designed to be substantially rotationally symmetrical with respect to an axis (16) directed from a first brewing chamber half (11) to a second brewing chamber half (12). The brewing chamber (10) has a maximum axial extension (17) in the direction of the axis (16), which is smaller than the largest diameter (18) transverse to the axis (16). Furthermore, the brewing chamber (10) has a thickness (19) in the area of the axis (16) which is equal to or smaller than the axial expansion (17).

Abstract: Brewing unit (3) for a beverage preparation machine with a first brewing chamber half (11) and a second brewing chamber half (12), which are arranged to be movable relative to one another from a closed position for forming a closed brewing chamber into an open position in which a capsule (60) can be inserted into the brewing chamber. The brewing unit (3) has at least one, preferably two, holding means (38) which hold a capsule (60) in an intermediate position in the open position between the first and second brewing chamber halves (11, 12) when the capsule (60) is inserted and release it when the brewing chamber is closed. Before release by the holding means (38), the first and second brewing chamber halves (11, 12) are spaced apart in such a way that the brewing chamber halves (11, 12) cannot grip a capsule (60).
