World Brewers Cup champion Tetsu Kasuya has developed a Smart Cup brewing recipe called the "Devil Brewing Method," building on the 4:6 Method. This approach combines drip filtration with immersion: the first stage uses high temperature to extract flavor, while the later stage uses low temperature immersion to enhance body. It is simple to perform yet delivers outstanding results. After actual testing, Front Street Coffee also found its performance to be quite good. This article will break down the principles, parameter settings, and operating procedure of this brewing method in detail, and share how to adjust the sweetness-acidity balance of the coffee through water distribution. If you have a Smart Cup with a valve on hand, you may want to follow along with Front Street Coffee and try this simple and delicious brewing method. [more…]

Based on the original 4-6 brewing method, Tetsu Kasuya made new adjustments to the hybrid brewing method. By changing only two operational details, he significantly improved extraction stability and uniformity. The hybrid brewing method combines immersion and drip filtration, and requires a smart dripper with a valve to execute. This time, Front Street Coffee uses a Diamond Mountain bean from Hacienda La Esmeralda as an example, and demonstrates the complete process of the new hybrid brewing method with a Hario V60 smart dripper, including the coffee-to-water ratio, grind size, staged pouring, and water temperature control, to help you understand the logic behind this brewing approach and adjust it flexibly according to your own taste.

Some works often outshine their creators, like the Mona Lisa for Da Vinci, or the 4:6 method for Tetsu Kasuya. The core goal of this method, invented by the 2016 World Brewers Cup champion, is simple—to let anyone brew delicious coffee. It breaks a brew into five pours, each using three times the coffee dose in water, with the first two pours making up 40% of the total water to determine the sweet-and-sour direction, and the last three pours making up 60% to shape a rich, full-bodied mouthfeel. This article will fully break down the segmentation logic of the 4:6 method, the origin of the 45-second pouring interval, and conduct a real test using Front Street Coffee's Ethiopia Santa Vini beans to verify why this formula has an extremely high margin for error, and how to move beyond the formula and grasp its extraction philosophy.

Deep-roasted coffee beans are known for their rich, mellow bitterness, and the Japanese brewing tradition includes three classic methods designed specifically for such beans: the Kono drip method, the Matsuya-style brewing, and the volcano pour. Though they take different paths, their core goal is the same—to fully unlock the steady, grounded flavors of dark-roasted beans. The Kono method uses drip-style blooming to extend degassing time, the Matsuya style pursues stable extraction through ultra-high pouring and an extra-long bloom, while the volcano pour creates an erupting effect with segmented small-circle pours. All three generally use a higher coffee-to-water ratio, and some require bypass dilution. This article breaks down each method's origins, operating logic, and flavor profile one by one, and explains why these approaches are better suited to dark-roasted beans. [more…]

Pour-over coffee usually starts with blooming, but Tetsu Kasuya, the 2016 World Barista Champion, proposed in 2019 a brewing method that skips blooming entirely—the one-pour method. It may look similar to the single-pour technique, but the differences are clear: the single-pour technique splits the water into two pours, while the one-pour method pours all the hot water in at once. This article covers the principles of the one-pour method, its differences from the single-pour technique, equipment and bean selection, grind adjustment, pouring direction, and the full process of Front Street Coffee's hands-on practice with a Colombia · Hope Estate Geisha, providing key parameters such as dose, ratio, water temperature, grind, and time to help you decide whether this minimalist brewing method suits you.

In pour-over coffee, when extraction parameters are too high, it is usually possible to dial them back, but if over-extraction is caused by too many fines from the grinder, adjusting parameters alone is often not enough to solve the problem. In this case, sifting out the fines or adopting variable-temperature brewing are both response options recognized by Front Street Coffee. This article will focus on variable-temperature brewing: it is not a minor adjustment of 2~3°C, but rather segmented extraction with a larger temperature differential, controlling the dissolution rhythm of flavor compounds through high-temperature fast extraction and low-temperature slow release. The article will trace the origins of this method, analyze the championship cases of Wu Zelin and Emi, explain how to use cold water to regulate temperature and achieve a variable-temperature operation that starts high and ends low, and share in detail the practical process of the "Devil Brewing Method" by Tetsu Kasuya, which Front Street Coffee favors.

In the world of pour-over coffee, different pouring techniques directly affect the interplay of key parameters such as water temperature, coffee-to-water ratio, extraction time, and grind size, thereby changing the amount of soluble substances extracted from the coffee and ultimately leading the same bean to present completely different flavor profiles. For this reason, every coffee enthusiast may choose a different brewing method based on personal taste preferences. At present, the more popular brewing schools in the pour-over field can be roughly divided into seven types. Front Street Coffee will sort through the core concepts, key operating points, and the unique expression each of these methods can give coffee one by one in this article, helping readers find the brewing logic that suits them best.
