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…]

Water temperature is a key variable in controlling the pace of coffee extraction. Most brewing guides set the recommended range at 86–93°C, and very few people dare to use water below 80°C or above 95°C on coffee. So what happens if you boil water and brew with it directly? This time, Front Street Coffee selected a medium-light roast Colombia·Frontera Big Navel and a medium-dark roast Indonesia·Mandheling, using conventional temperature and boiling water for comparison, and compared concentration, aroma, and mouthfeel item by item. The article not only provides two sets of measured data, but also explains how temperature affects the release of sourness and bitterness, as well as the suitable water temperature ranges for light roasts and dark roasts respectively, helping you understand whether 92°C is really a hard standard that must be followed.

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 people attribute this to the beans themselves and give up on further adjustment. But in fact, unclear flavor often has nothing to do with the beans—it's certain variables in the brewing process that have gone wrong. Drawing on Front Street Coffee's practical experience, this article sorts out four core reasons that may lead to vague flavor—coffee concentration being too high, over-extraction, coffee beans being too fresh, and brewing water being too hard—and provides specific adjustment plans for each situation to help you rediscover the flavor layers of your pour-over coffee.

After specialty coffee became popular, light roasting gradually became the mainstream, and coffee's flavor shifted from a single note of bitterness to a layered richness of acidity. However, many people brewing at home always feel that the same beans taste noticeably different from what they get in a café—in the café, the sweetness and acidity are balanced, while what they brew themselves is sharp and astringent, like biting directly into a lemon. This gap usually stems from two aspects: first, the beans themselves have relatively high acidity; second, insufficient extraction prevents sweetness and bitterness from being released in time. This article will start with three key variables—grind size, extraction time, and brewing water temperature—to explain how to bring the sweet-to-sour ratio of light-roasted coffee back into balance, and will include a complete brewing demonstration of Front Street Yirgacheffe·Gededing for reference.

To make delicious cold brew coffee, Front Street believes three things are essential: choosing floral and fruity coffee beans: since cold brew coffee is extracted at low temperature over a long period, more small-molecule substances in the coffee beans such as floral notes and fruit acids are extracted, while large-molecule substances such as tannic acid and other bitter compounds are difficult to extract. [more…]

How long exactly should the extraction time for pour-over coffee be controlled? Is two minutes truly an unshakable standard?

Understanding flavor as merely two directions—sour and bitter—misses the layers of aroma, sweetness, body, mouthfeel, and finish. When choosing beans, first determine whether you lean toward floral and fruity notes, nutty and cocoa notes, or a balance of both, then make your decision based on origin, processing method, and roast level. As a steam-pressure device, a moka pot's coffee bed only needs to be filled level with the filter basket. [more…]
