When brewing pour-over coffee, the timer function on a digital scale is often overlooked, yet it is crucial for judging extraction results. Front Street Coffee recommends keeping the total extraction time at around 2 minutes, in practice falling between 1 minute 50 seconds and 2 minutes 10 seconds. However, there is disagreement over when to start the timer: should it begin the moment water is poured, or should the clock only be started after pouring is finished? Front Street believes that extraction begins the instant the coffee grounds touch water, and therefore insists on timing from the very first second of pouring. This article builds a pouring model around time milestones, explaining how to troubleshoot issues such as flow rate and grind size through segmented timing, making time an effective diagnostic tool for brewing.

Coffee extraction, simply put, is the process of using water to dissolve the flavorful essence from coffee beans. It seems like something that can be summed up in a single sentence, but behind it lies a whole series of precise variables: extraction yield, total dissolved solids, water quality, grind size, temperature, time, and more. Roasted coffee beans are about 30% soluble, and what we aim for is extracting 18-22% of that—the optimal range. We don't want under-extraction, which leads to sharp acidity and a thin, bland cup, nor over-extraction, which brings bitterness and off-flavors. This article will start from the basic definition of extraction and break down, one by one, the nine core factors that affect extraction, helping you build a systematic framework for understanding brewing so that every cup consistently delivers the ideal flavor.

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.

In pour-over coffee, staged pouring is a common technique for regulating flavor. The three tastes in coffee—acidity, sweetness, and bitterness—are not released at the same rate; hot water draws them out in sequence. This article uses Front Street Coffee's medium-roast Papua Bird of Paradise coffee beans as an example. With 15g of grounds, 225ml of total water, and a water temperature of 89°C, it employs three-stage and four-stage pouring respectively to compare the flavor differences in the early, middle, and late coffee liquid, helping you find the extraction stage where sweetness is most concentrated. It also explains how the number of stages affects extraction yield, operating time, and the risk of over-extraction, and offers practical ideas for improving the efficiency of sweetness extraction.

There is more than one way to extract with a siphon brewer. With the same set of equipment, switching your approach to stirring or steeping will steer the flavor in the cup in a different direction. This article starts from Front Street Coffee's brewing experiments, using the Costa Rica Canet Estate Mozart, a raisin honey-processed bean, to compare the stirring method and the steeping method. In the stirring method, a cross-shaped stir is performed 30 seconds after the coffee grounds contact the water to break the crust, the heat is removed at 56 seconds, and the total extraction time is 1 minute 8 seconds; in the steeping method, the coffee grounds are left to sit for 1 minute before the heat is removed, and the total extraction time is 1 minute 32 seconds. The two approaches each emphasize different aspects of aroma, mouthfeel, and sweet-tart expression, suiting different taste preferences. The article also covers the working principle of the siphon brewer, parameter suggestions, and key points for maintaining the cloth filter, helping coffee enthusiasts brew a cup of rich, full-bodied, aromatic coffee more consistently.

Segmented pouring in pour-over coffee is one of the core techniques that many enthusiasts focus on. So-called segmented pouring means dividing the total water volume after blooming into multiple pours, with a waiting period between each pour to let the water in the dripper drain first. The choice of this waiting timing—whether to wait for the water to drain completely before pouring the next segment, or to pour when the water level is about to reach the bottom but has not yet fully drained—directly affects the total extraction time and the final flavor. Front Street Coffee once conducted a dedicated experiment on this and found that waiting for the water to completely finish draining before pouring again extends the extraction time, and the extent of that extension depends on the density and hardness of the coffee beans. Starting from Front Street's answer, this article will systematically sort out the purpose of segmented pouring, the differences in pouring timing, and the criteria for judgment in actual operation, helping pour-over enthusiasts find a brewing rhythm that suits them.
