Beer drinkers hear in advertisements again and again about the importance of the right water for brewing a good beer. When revisiting the first issues of Brewing 101, one can read about the major influence of hop and malt raw materials, about the importance of brewhouse operations and unit operations in the fermenting room and storage cellar, about the influence of yeast and that the most attractive beer, ultimately, can be ruined during filling. So why should water, above all, have a significant influence, it is just water? We will soon learn that water quality and composition are very relevant for subsequent beer quality.
