Provided are methods for automatically producing milk froth in a milk-frothing apparatus, and also a milk-frothing apparatus for automatically producing milk froth. The milk-frothing apparatus has at least one hollow space, a steam-inlet channel for introducing steam into the hollow space, a milk-inlet channel for introducing milk into the hollow space, an air-inlet channel for introducing air into the hollow space, and an outlet channel for discharging milk froth from the milk-frothing apparatus, wherein the respective channels each issue directly or indirectly into the hollow space. With the aim of specifying a method and a milk-frothing apparatus by means of which an organoleptic milk froth of which the taste is optimized can be automatically produced, the invention makes provision for steam, preferably steam from water, to be introduced into the steam-inlet channel in order to allow milk and air to flow into the hollow space and in order to mix said milk, air and steam to form a milk/air/steam mixture, and to then output the milk/air/steam mixture into the outlet channel, wherein a sweetening means is provided in a region of the milk-frothing apparatus through which at least the milk/air/steam mixture flows.

A coffee machine with an integrated coffee grinder and a powder chute, which serves the purpose of feeding ground coffee from the coffee grinder to a movable brewing cylinder, has an inlet with a manually operated lid for already ground special coffee. A sensor detects the position of the lid. The detection signal of the sensor is passed on to a processor controlling the coffee machine, and the signal is used to differentiate between a normal operating mode and an operating mode for producing special coffee. If the lid is opened for a certain minimum time span, a subsequent coffee preparation cycle in the operating mode for producing special coffee is initialized. Since, to that end, no separate pre-selection is required any longer, the operation of the coffee machine is simplified and the susceptibility to problems is reduced.
