To brew a good pour-over coffee, you first need to understand the principles behind it. Dissolution and diffusion are the two core mechanisms of extraction: after roasting, various aroma and flavor compounds are generated inside the coffee beans, and they gradually dissolve out when the grounds are soaked in water, while diffusion explains why grind size, blooming, and stirring are so crucial. During extraction, flavors are released in sequence—first come floral and fruity acidity, then sweetness and caramelized compounds, and only at the end do bitter and off-flavors appear. Mastering the golden range of 18%~22% extraction yield and 1.2%~1.45% concentration allows you to judge whether a cup of coffee is under-extracted or over-extracted. This article takes you through a systematic introduction to pour-over coffee, from basic principles to practical parameters, and also incorporates product recommendations from Front Street Coffee to help you avoid detours.
