A brewing facility for a coffee machine comprises a brewing cylinder (6) and an upper plunger (3) and a lower plunger (4) by means of which a brewing chamber is formed. The brewing cylinder (6) and the plungers (3 and 4) are held in a frame (2) such that they can be shifted, and can be driven by means of a driving facility. For adding the coffee powder, a coffee powder feed facility is provided which in turn is provided with a swivel-type funnel (14), which can be moved against a spring force from a filling position into a swiveled-away position, and vice versa. The swivel-type funnel (14) can be swiveled further from the swiveled-away position to a fully swiveled-out position and, in said fully swiveled-out position, can be locked by locking means (29) and unlocked by unlocking means (30). In this way, the swivel-type funnel (14) can be held in the fully swiveled-out position during the cleaning of, in particular, the upper plunger (3).
