Karlsruhe mixture

The Karlsruhe blend is a full-bodied, aromatic roast and our popular "home variety". We have tailored this ETTLI coffee directly to the needs of the people of Karlsruhe based on the hardness of their water. Water hardness always goes hand in hand with the pH value. Hard water has a more alkaline reaction. This is why the fruit acids found in Arabica coffees are neutralized by the alkaline character of hard water. In addition, the hardness-forming minerals develop an undesirable off-flavor. This is anything but desirable. Soft water up to 6°d, on the other hand, is rather acidic, in extreme cases even curdling cream. Fully softened, i.e. acidic, water intensifies the acidic taste of acid-intensive green coffee varieties, light roasts or fast-roasted coffee. With this knowledge, ETTLI constantly checks the water quality on site and roasts the Karlsruhe blend in such a way that it is optimally adapted to the local conditions and produces the best possible taste experience.
