Beyond varietal differences, coffee beans have multiple classification dimensions, which gives rise to many alternative names. This article begins with the appearance-based classification of flat beans and round beans, and focuses on answering the question coffee enthusiasts often ask: what exactly does "hard bean" mean? It originates from a grading system in Central American growing regions that classifies bean hardness by cultivation altitude—the higher the altitude, the greater the density and the higher the grade. The article also shares how to judge bean hardness by feel, the roasting and brewing strategies corresponding to coffee beans of different hardness, and uses actual brewing parameters as examples to illustrate the differences in extraction between high-hardness light-roasted beans and low-hardness dark-roasted beans, helping readers find a suitable brewing approach.

Baristas often mention hard beans and soft beans, but these two terms actually do not refer to whether the beans feel hard or soft to the touch—they refer to the density of the coffee beans. The concept of hard beans comes from the Central American coffee grading system, which uses altitude as the standard—the higher the altitude, the lower the growing temperature, the slower the coffee fruit matures, the more flavor compounds it accumulates, and the greater the bean density becomes. Panama, Costa Rica, Guatemala, and other countries generally adopt this logic, while Ethiopia, because its overall altitude is high, is almost entirely made up of extremely hard beans and does not need further subdivision by altitude. Of course, although high-density beans are delicious, they also bring more challenges during grinding and brewing. [more…]

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.
