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.

The 4:6 brewing method was created by粕谷哲, the 2016 World Brewers Cup champion, and its core idea is to let everyone brew good coffee easily. This method splits the total water volume into five pours: the first 40% determines the flavor direction, and the latter 60% shapes the mouthfeel and strength. By adjusting the water volume of each pour, you can change the coffee's sweet-acid balance and body. In this article, Front Street will break down the pour proportions of the 4:6 method in detail, explain the principles behind extraction yield changes, and provide complete brewing parameters. At the same time, we will use Front Street Ethiopia Hachira beans for a hands-on demonstration to help coffee lovers deeply understand the essence of extraction and easily brew a delicious pour-over coffee.

The 4:6 method was created by Tetsu Kasuya, and its core idea is to let anyone brew a consistently good cup of coffee. It splits a single pour into five stages: the first 40% of the water governs the flavor direction, while the latter 60% determines the strength of the body. Combined with an extra-coarse grind and fixed intervals, it greatly lowers the barrier to water control. This article lays out the standard parameters of the 4:6 method in full, including dripper choice, coffee-to-water ratio, grind passing rate, water temperature, and pouring rhythm. It also takes a deep look at the logic behind the coarse grind and the 45-second intervals, explains how adjusting the ratio of the early and late stages changes the sweet-and-sour profile, and shows how increasing or decreasing the number of stages lets you control body, helping you apply this method flexibly.

At the 2021 WBrC World Coffee Brewing Championship, champion Matt won with a blend rather than Geisha, sparking widespread attention. His recipe consisted of 60% naturally processed Eugenioides and 40% washed Catuai; the former provides extremely high sweetness, while the latter brings clear acidity. In brewing, he used a metal V60 dripper, a 1:15 coffee-to-water ratio, five-pour pouring, and innovatively controlled the water temperature in two stages: 93°C and 88°C. Through video analysis, Front Street Coffee found that his pouring ratio closely resembles Tetsu Kasuya's 4:6 brewing method. This article provides a complete analysis of this competition regimen, which balances sweetness and complexity and offers extremely high compatibility, for coffee enthusiasts to reference and learn from.

The extraction time of pour-over coffee is not an isolated number; it has a positive correlation with the extraction yield. When the extraction yield falls within the generally accepted ideal range of 18% to 22%, the coffee flavor usually performs better, and when this range is projected onto the time axis, it forms an optimal time range tied to a specific brewing recipe. Front Street Coffee uses the example of a light roast with 15 grams of grounds, a 1:15 ratio, 91°C, an 80% pass rate through a No. 20 sieve, and a three-stage pour, giving a reference range of 1 minute 50 seconds to 2 minutes 10 seconds. However, many enthusiasts find that even with identical parameters, the actual drip time may still be longer. This is often related to factors such as the grinder's particle size distribution and pouring habits. This article will break down these variables one by one and introduce the 4-6 brewing method, which uses time itself as a control lever, to help readers master the rhythm of pour-over more calmly.

This is already the third Peruvian single-origin bean Front Street has featured recently. La Capia is located in the Cajamarca region of Peru; six or seven years ago it was still a sugarcane field. As demand for sugarcane declined, farmers planted their first coffee trees in small experimental plots, and unexpectedly discovered that the high altitude and abundant rainfall created a microclimate ideally suited to coffee growing. Since then, six smallholder farmers have worked together, letting coffee flourish alongside native vegetation—and that is how this Front Street Peruvian washed Cajamarca came to be: 1,550 to 1,900 meters above sea level, a mix of Bourbon, Caturra, and Typica, washed processing, offering citric acidity, a rounded mouthfeel like milk chocolate, and a sweet yellow-sugar finish. At the end of the article are three tested brewing recipes for Chemex, V60, and Kalita Wave, for pour-over enthusiasts to reference and replicate. [more…]

The AeroPress, with its极高 playability, attracts many coffee enthusiasts to get involved, and the official organization even holds专属 competitions every year to see who is the best at "playing" with it. In this article, Front Street is going to share a universal extraction recipe from an AeroPress champion—this champion is none other than粕谷哲, the 2016 World Coffee Championship winner and inventor of the famous 4:6 method. This recipe adopts a high-concentration, low-extraction approach, using a large dose of coffee to extract a small amount of highly concentrated coffee liquid in a short time, then diluting it with water or ice to make a hot or iced drink. Using an Ethiopian Hamashu light-to-medium roast floral and fruity bean as an example, Front Street records in detail the dose, grind size, water temperature, extraction time, and inverted pressure operation steps, and also provides by-pass dilution suggestions and flavor tasting references. Friends who have an AeroPress at home should definitely give it a try. [more…]
