In the iced coffee family, there are many names—cold brew, ice drip, iced brewed, cold steeped, Dutch coffee, Kyoto coffee—that often leave people bewildered. This article starts from the broad concept of cold brew coffee, sorts out the two major low-temperature extraction paths of immersion and drip filtration, traces the origin of Dutch coffee, the process by which Japan's Hanabusa Coffee invented the three-layer ice drip pot, and the emphasis on the brewing and aging step behind the term "iced brewed." The article also presents five Front Street single-origin beans suitable for making iced brewed coffee, covering Yirgacheffe, Kenya, Panama Butterfly, Costa Rica Mozart, and Strawberry Candy Geisha blend, explaining each one's origin, altitude, variety, and processing method, and noting the flavor performance of medium-light roasts in cold brew.

The most fascinating thing about cold brew is that it works like a slow-motion projector: the flavor release that hot extraction completes in a few dozen seconds is stretched out over more than ten hours, and the character of every flavor compound is amplified and put on display. Running a set of cold brew comparison experiments with beans processed in different ways lets you directly see how each processing method truly expresses itself at low temperatures. The experiment is set [more…]

When faced with coffee beans processed in different ways, is it necessary to design a separate brewing recipe for each one? Front Street believes that rather than recording tedious parameters one by one and bearing the high cost of trial and error, it is better to categorize beans by processing method or roast level and use a single recipe with a broad coverage range. This article focuses on three processing methods—natural, washed, and anaerobic—explaining the differences in their flavor expression, as well as the targeted adjustments that can be made during brewing, including the thinking behind setting water temperature, coffee-to-water ratio, grind size, and extraction time. The article also specifically explains why anaerobically processed coffee drains faster, and how to ensure full extraction by grinding finer or switching to a slower-flow filter basket. All parameters are based on medium-light roasted beans, with adjustment suggestions for medium-dark roasted beans included. [more…]

After trying a few cold brews, many people ask: with the same method, why do some cold brews taste like fruit juice while others taste like cold bitter water?

Origin determines the flavor baseline. Coffee beans from different origins have flavors [more…]

Ethiopia is the birthplace of coffee and one of the important producing regions of the Geisha variety.

Many coffee enthusiasts encounter a puzzle when brewing anaerobically processed coffee beans: even when they follow the grind standard for a medium roast, the water flow is noticeably fast, and the resulting cup tastes thin and lacks complexity. Behind this phenomenon is actually a close relationship with the changes that anaerobic fermentation brings to the cellular structure of coffee beans. Starting from Front Street's actual brewing tests, this article combines grind particle-size distribution data from anaerobically processed beans such as Rose Valley and Mozart to analyze the causes of the faster flow rate, and offers adjustment suggestions on both grind setting and pouring technique, helping you reproduce at home an anaerobically processed coffee that is rich in aroma and smooth in mouthfeel.

Compared to other conventional processing methods, anaerobically processed coffee beans usually have a more intense and more distinctive flavor (for the most part), because their fermentation tends to go a bit deeper.

Coffee processing encompasses three levels: the processing methods that extract coffee beans from coffee cherries, the brewing methods that extract coffee liquid from coffee beans, and the industrial processes that turn coffee liquid into instant coffee powder. Traditional processing methods include three types—washed, natural, and honey—each giving coffee beans a distinctly different flavor profile. Extraction methods fall into three mainstream categories: drip, pressure, and cold brew, corresponding to pour-over coffee, espresso, and cold brew coffee, respectively. As for instant coffee, regular instant and freeze-dried coffee also show clear differences in production techniques and flavor retention. This article will break down these processing stages one by one to help coffee enthusiasts build a complete knowledge framework from seed to cup. [more…]

Semi-washed and honey processing both belong to the category of methods where the fruit skin is removed and the beans are dried directly, yet they present截然不同的 flavor directions due to differences in how much pectin is retained and the drying conditions. Semi-washed originated in Brazil; it is simple to operate and suitable for large-scale production, with a flavor profile leaning toward nuts, chocolate, and caramel; honey processing began in Costa Rica and, depending on the proportion of pectin retained, is classified into yellow, red, and black grades, with sweetness and aroma being more prominent. This article will systematically sort out the process steps, flavor characteristics, and grading logic of the two, and, combined with Front Street Coffee's Brazil Red Bourbon and Costa Rica Honey Process Geisha, provide specific brewing parameters and technique suggestions to help coffee enthusiasts understand the differences and apply them to daily brewing.
