Coffee drinks consist of up to 99% water. Water is a decisive factor for coffee flavor and the longevity of your portafilter machine or other equipment used.

Why do we sell the BWT test kit?

In addition, careless use of simple tap water can lead to premature calcification or even more serious damage to your portafilter machine.
