Brewing apparatus with a drainage valve

A brewing apparatus for producing coffee beverages, comprising

• a liquid container for a brewing liquid or a decalcification liquid,
• a brewing unit including a brewing chamber being configured for brewing coffee,
• an outlet,
• a drainage valve being configured to be brought into three different positions, wherein the three different positions include a brewing position, a drainage position and a decalcification position, wherein the drainage valve is arranged with respect to the liquid container, the brewing unit and the outlet so that,
• when the drainage valve is in the brewing position a brewing liquid path is provided between the liquid container and the brewing chamber via the drainage valve enabling an amount of the brewing liquid to flow via the drainage valve into the brewing chamber for brewing coffee with the brewing liquid in the brewing chamber, and,
• when the drainage valve is in the drainage position a drainage liquid path is provided between the brewing unit and the outlet via the drainage valve enabling a drainage luquid coming from the brewing chamber to flow via the drainage valve to the outlet, and,
• when the drainage valve is in the decalcification position a decalcification liquid path is provided between the liquid container and the outlet via the drainage valve enabling an amount of the decalcification liquid to flow from the liquid container via the drainage valve to the outlet, and
• wherein the drainage valve is configured to block the drainage liquid path when the drainage valve is in the brewing position and to block the brewing liquid path when the drainage valve is in the decalcification position.
