Hot beverages consist of up to 98% water—no doubt that this ingredient plays a vital role during preparation. Water quality may vary by region. For example, if the composition of minerals contained in the water is not balanced, the aroma cannot fully develop. Water quality is of central importance for the machines as well. Using a AROMATECH water filter prevents the scale deposits building up in your machine which can lead to breakdowns and limited efficiency.

Ideal coffee water is fresh and pure in taste and has no discernible scent. It should be mineral-rich, yet have a balanced mineral content. A total hardness of 7–12°EH, a carbonate hardness of 3–4°EH and a pH value of 6.5–7.5 are ideal (Source: Deutscher Kaffeeverband). Only then can coffee develop its full aroma.

Espresso, cappuccino, latte macchiato—the coffee bean business is booming, and with that, come higher quality requirements from the individual ingredients, especially water. For this reason, it is almost impossible to conceive a professional coffee machine without an integrated water filter.
