Abstract
The invention relates to a beverage preparer (,), in particular a coffee machine, with a first beverage region for the preparation of first and second beverages, with a second beverage region for the preparation of third beverages, and with a pressure-raising stage (M,) to generate a first liquid pressure, such that in a first operating mode in the first beverage region the first beverages, in particular pressurized coffee, can be prepared at the first liquid pressure and such that in a second operating mode in the first beverage region second beverages, in particular brewed coffee, can be prepared at a second, lower liquid pressure. The pressure-raising stage (M,) on its output side is connected to the input (I,) of the second beverage region by way of a pressure reducer (D,). The input (I,) of the second beverage region comprises a pipe connection to an input (I,) of the first beverage region that can be blocked by an operating-mode switch apparatus (Y,) in such a way that, depending on the state of the operating-mode switch apparatus, in the first beverage region either the first or the second liquid pressure prevails.
