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…]

Many coffee enthusiasts encounter an awkward situation when they first start brewing pour-over: the coffee they brew doesn't taste bad, but the flavor is always vague—they can't quite put their finger on what it actually tastes like.

Many coffee enthusiasts are often puzzled when tasting pour-over: why are fruity notes like citrus and pineapple easy to identify, while the sweet aromas of strawberry and peach always seem veiled? Front Street approaches this from the perspective of aroma chemistry composition and concentration differences, revealing the fundamental reason these fresh fruit notes are hard to capture—authentic strawberry aroma is presented through the synergy of over three hundred volatile compounds, while coffee contains only a small amount of similar components. The article proposes two paths to solve this: first, training the sense of smell to capture secondary aroma contours beyond the primary notes; second, amplifying target flavors through high-temperature fast extraction and appropriately diluting the coffee-to-water ratio in brewing strategy. Front Street also lists several sun-dried bean options with peach and strawberry notes, and using Ethiopia Hamashu as an example, provides complete brewing parameters and tasting records. [more…]
