Many pour-over beginners don't run into clogging issues while brewing, yet after finishing, the coffee bed ends up perfectly flat, with no indentation at all. This shows that water flow control during extraction wasn't up to par, so a bowl-shaped bed couldn't form, which very easily leads to uneven extraction. Front Street has summarized three common mistakes: the bed wasn't lifted high enough, the water flow lacked enough stirring force, and the pouring circles were too wide in amplitude. We'll go through the causes one by one and give adjustment methods for each. Also, the depth of the coffee bed has no necessary connection to the roast level—whether you can produce a bed depression depends on your pouring technique, not how the beans were roasted, while the depth of the depression is determined by the dose of coffee.

From seed to cup, roasting is the key step that unlocks flavor. The degree of roast affects not only the balance of acidity and bitterness but also whether the mouthfeel is light or rich. This article begins with the roasting stages, introduces how the SCA Agtron scale quantifies roast level, and explains why a light roast preserves the origin's true character while a dark roast delivers intensity and depth. It then uses Ethiopia Yirgacheffe and Indonesia Golden Mandheling as examples to show how Front Street Coffee chooses roast levels based on each bean's characteristics, ultimately producing completely different tastes in the cup. Whether you prefer fruity acidity or rich depth, understanding roast level will help you find the flavor you love more precisely. [more…]

Extraction water temperature of 100°C, a bloom lasting as long as 180 seconds, a coffee-to-water ratio of 1:5, plus lid-on blooming, ultra-high pouring, and a large amount of bypass water—Matsuya-style brewing seems extreme in every respect, yet it was once believed to consistently produce good coffee and even took Japan by storm for a time. When Matsushita Yoshikazu created this method in 1962, measuring tools were not yet widespread, so he used techniques like boiling water, high pouring, and bypass to replace the thermometer and digital scale. Today, Front Street Coffee takes you through an in-depth breakdown to see what logic and wisdom lie behind these seemingly counterintuitive operations. [more…]

The African continent has long been renowned for producing high-quality coffee, and Kenya, neighboring Ethiopia, is one of the countries with extremely strict standards for cultivation and quality management. Whether from large estates or smallholder farmers, all coffee beans must be processed and then sent to the Kenya Coffee Board for unified cupping and grading. This article will provide an in-depth analysis of the sources of Kenya coffee's unique flavor, from the aluminum, iron, and other elements abundant in its red soil to its distinctive aroma and prominent acidity, and will introduce Front Street Coffee's recommended descriptions of Kenya coffee's flavor characteristics.

When coffee beans take on an oily sheen, does that mean they are no longer fresh? And why is the golden, dense foam on top of an espresso sometimes thin or even missing? These two common questions actually point to the same core issue—the roast level of coffee beans and the release of carbon dioxide. This article will take a deep dive into the science behind oil appearing on dark-roasted beans, explaining that the amount of oil is unrelated to quality and depends more on roast depth and varietal differences. It will also systematically explain the criteria for judging crema on the surface of espresso, its visual and taste value, and key factors from bean selection, roast level, and peak-flavor window to extraction equipment and parameters, helping you consistently achieve a rich, thick crema. The article also recommends two Front Street Coffee espresso blends, for reference whether you are opening a shop or brewing at home. [more…]

After brewing is complete, the state of the coffee bed can reveal a lot about the extraction, and the color of the coffee liquid is also often used as a basis for judgment. Many people, upon seeing darker-colored coffee, instinctively assume it tastes stronger, or even suspect it is murky. In fact, the depth of color is related to extraction yield and roast level, but it does not directly equate to a higher or lower level of clarity. This article starts with the color of the coffee liquid, analyzes whether dark color indicates murkiness, and, using Front Street Coffee's comparative brewing examples, explains how to judge clarity through taste rather than sight, while also offering practical advice on bean selection, resting beans, parameter control, and pouring technique.
