Water makes up 98.5% of coffee, which means that water quality is of great importance. Your coffee and the coffee machine will be affected if the water does not meet requirements due to regional differences. We recommend you always use a BRITA water filter. Very hard, calcareous water can give a bitter or even sour taste to coffee, for example. And the chalkier the water, the faster the machine will collect limescale. This could result in high costs, as the machine wears faster and uses more energy unnecessarily.
The ideal water for coffee is fresh and tastes pure, without any discernible odour. It should be rich in minerals, but also balanced. Only then can the coffee develop its full aroma, and tea its perfect colour.
