Water filtration (cafe-grade)

Cafe-grade water filtration is a specialized treatment system that purifies tap water and balances its mineral content specifically for brewing coffee. Since a cup of black coffee is roughly 98% water, the chemical makeup of what comes out of the tap dictates the entire flavor experience. Standard tap water often contains too many heavy minerals that mask delicate fruit and flower notes, whereas completely empty water leaves the cup tasting flat. Professional systems use specialized cartridges to remove impurities like chlorine while keeping the exact amounts of magnesium and calcium needed to dissolve the best flavors from the ground coffee. Many specialty cafes test their water composition frequently, as city water chemistry changes naturally with the changing seasons.
