Water accounts for over 98% of brewed coffee, yet it has long been overlooked. Different types of water—RO water, tap water, mineral water, soft water, hard water—have a huge impact on extraction flavor. In 2014, Christopher Hendon and Maxwell Colonna-Dashwood published research revealing how sodium, calcium, and magnesium ions influence the extraction efficiency of flavor compounds, and subsequently published the book "Water for Coffee," which systematically discusses the dynamic balance between GH (total hardness) and KH (carbonate hardness), and proposes the reverse thinking of "Roasting to water." This article will sort out these key findings to help coffee lovers understand how water quality shapes the flavor in the cup, and will retain relevant recommendations for the Front Street brand.
