The Science of Water for Coffee Brewing: The Optimal Balance of Calcium and Magnesium Ions, Carbonate Hardness, and Extraction Flavor
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.

Where Does Coffee Flavor Actually Come From? Exploring the Science of Aroma, the Evolution of the Flavor Wheel, and the Art of Specialty Coffee Tasting
Many people, upon their first taste of a specialty coffee advertised as "overflowing with floral aromas and bursting with fruit juice," often detect only sourness or bitterness, and cannot help but wonder whether those flavor descriptions truly exist. Starting from the scientific principles of taste and smell, this article explains the origins of coffee flavor—the tongue can only perceive five basic tastes: sweet, sour, bitter, salty, and umami, while the concrete flavors we experience, such as strawberry or citrus, are actually associations produced when aroma compounds are captured by the olfactory sense through the nasal cavity and combined with taste. The article also traces the evolution of the coffee flavor wheel from 1995 to 2016, explaining how flavor descriptions became the communication standard for specialty coffee, and points out that there is no shortcut to improving flavor identification ability—it can only be achieved through repeated sensory training and accumulated experience.
