Which pour-over coffee brewing method suits which beans?

Pour-over coffee covers several distinct methods. Single-cut blooms with 30ml and then pours the remaining 195ml at once for a 15g dose and 225ml total, finishing in about two minutes with a clean, stable result. The three-stage method stages pours to follow extraction order: sour first, then sweet, then bitter. The 4-6 method is formulaic, the three-temperature method varies water heat, volcano pour suits dark roasts, and agitation demands skill.

The choice comes down to what a bean needs. Single-cut limits late-stage extraction and keeps flavors clean, while staged pouring builds layers by drawing out sweetness before bitterness arrives. The variable-temperature approach highlights specific notes by shifting heat between pours. For the coffee enthusiast working through a new bag, matching method to roast level and desired clarity matters more than any single fixed recipe.

The charm of pour-over coffee lies in the diversity of brewing methods. Beyond the common three-stage pour, there are also single-cut, four-six, three-temperature, volcano pour, agitation method, and many others. Each method has its own characteristics: single-cut is simple and stable, three-stage offers rich layers, four-six is formulaic, three-temperature highlights flavors through variable-temperature extraction, volcano pour is highly visual and suits dark roasts, and the agitation method demands considerable skill. This article will analyze the principles, parameters, and suitable scenarios of these brewing methods one by one, and share Front Street Coffee's practical experience, helping coffee enthusiasts understand the logic of flavor release and find a brewing approach that suits them.

Compared to other single-origin coffees, pour-over coffee shows extremely rich diversity in its preparation methods. For example: single-cut, three-stage, volcano pour, variable-temperature brewing, agitation method, and so on. Today we'll sort through several of the more common brewing methods in pour-over coffee.

I. Single-Cut Single-cut is not entirely the same as one-pour. One-pour means pouring all the target water in a single go; single-cut, by contrast, is divided into two stages—the first for blooming, and the second pouring the remaining water all at once. Because both the brewing theory and the operation are relatively easy to understand, this technique can be seen on many occasions.

Its name also has quite a history—"single-cut" comes from a school of Japanese swordsmanship. The reason for this naming is probably that the pouring stages look as if cut off by a single stroke, hence divided into two stages. Taking 15g of grounds and 225ml of water as an example, the staged water amounts for single-cut are 30ml for blooming plus a one-time pour of 195ml, with a total extraction time of about 2 minutes. The characteristics of this brewing method are stable extraction and a relatively clean flavor, because it does not over-extract the later-stage substances.

II. Three-Stage This is Front Street's most commonly used brewing technique—"three-stage." The dissolution rates of different substances in coffee vary greatly. Simply put, the order in which hot water releases flavors is: first sour, then sweet, then bitter. Staged pouring is meant to extract the aromatic substances held in the coffee as fully as possible.

Also taking 15g of grounds and 225ml of water as an example, three-stage is divided into 30ml for blooming, a first pour of 95ml, and a second pour of 100ml, with a relatively longer extraction time. Aside from the blooming stage, under the same coffee-to-water ratio, the more pouring stages there are, the more times the coffee bed is washed, and the time is extended accordingly. Coffee extracted with the three-stage method dissolves flavor substances more fully, adding layers and offering greater compatibility.

III. Four-Six Method The "four-six method" was invented by Mr. Tetsu Kasuya of Japan. His philosophy in creating this method was that "anyone can brew delicious coffee." Hence this method is very simple—it does not require particularly stable water control, nor a deep understanding of brewing. As long as you operate according to the formula, you can brew a quite decent cup of coffee.

Kasuya's understanding of four-six brewing is: the first two pours amount to 40% of the total water, mainly serving to determine the direction of the coffee's flavor and guiding sour and sweet into balance; the remaining three pours amount to 60% of the total water, determining the strength of the coffee's mouthfeel, that is, its body.

The most commonly used dose for the four-six method is 20g of grounds with 300ml of water, brewed in five stages of 60ml each, with a 45-second interval between pours (the interval includes the pouring time). Although Kasuya says it is simple, quite a few people still have a high failure rate after using four-six brewing, and most of those failures are over-extraction. Because the extraction time is long, many people do not adjust the grind, leading them to brew directly with a conventional grind particle size, ultimately causing over-extraction.

So we need to adjust the grind to a coarser setting to compensate for the over-extraction that a long extraction time tends to bring. Front Street generally uses coarse particles with a 50% pass rate on a No. 20 sieve. After a long extraction, such particles brew a coffee with a full-bodied mouthfeel that regular coffee does not have.

IV. Three-Temperature Brewing Method The three-temperature brewing method, invented by Mr. Wu Zelin, actually belongs to variable-temperature brewing—as the name suggests, it uses water at different temperatures for brewing. He uses 16g of grounds as the baseline, then brews with 240ml of water in four stages of 40ml, 60ml, 60ml, and 40ml respectively. The first two stages use a water temperature of 94°C, the third stage uses a slightly lower 90°C, and the final stage uses 80°C, thus forming a stepped variable-temperature extraction.

The concept of variable-temperature extraction is also fairly easy to understand: use a higher water temperature to extract the rich flavor substances in the early stage, then finish with a lower water temperature to avoid the risk of over-extraction caused by continuous high-temperature extraction. But this brewing method is somewhat difficult—it requires a lot of brewing tests to find the temperature standard that suits the current coffee beans. So once you have established a suitable temperature standard, you will ultimately get a cup of coffee with a strong flavor expression.

V. Volcano Pour This brewing technique comes from Japan. Its name originates from the carbon dioxide contained in the coffee beans, which forms a large dome together with the coffee fines floating on the surface, looking like a great mountain. The hot water poured into the center accelerates the degassing of the coffee grounds, looking just like a volcanic eruption—hence the name volcano pour.

It is more suitable for brewing dark-roasted coffee beans, because only dark-roasted beans can release a sufficiently large amount of gas to form the mountain shape. The dripper used is a fan-shaped one, with a dose of 30g—the more grounds, the better the visual effect of the volcano—and a slightly coarser grind. Then brew with 300ml of hot water (1:10 coffee-to-water ratio), first blooming with twice the weight of the grounds in hot water for 30 seconds, then pouring repeatedly at the center in multiple, small, gentle pours. There is no limit on each pour; when the water level starts to drop, you can proceed to the next pour, until the target amount of water is poured.

The volcano pour has two distinctive advantages. The first is its extremely high visual appeal—while brewing coffee you also enjoy a visual feast. The second is that the coffee it produces has a balanced mouthfeel, high sweetness, and no bitterness. Friends who like dark-roasted coffee may find it worth a try.

VI. Agitation Method The rise of the agitation method originated with Matt Perger, the 2012 World Coffee Brewing Championship winner, who used this technique in the competition to win the championship. He later uploaded a video to an overseas video site, in which he used a wooden stick during the blooming stage to stir quickly—first up and down, then left and right, then up and down again.

But the agitation technique is relatively difficult. The coffee fines, due to the turbulence caused by stirring, migrate downward to the bottom of the dripper, easily causing clogging. Secondly, because there is no unified technique or force, everyone stirs in their own way, and one person's stirring cannot be borrowed for another's technique—many only look the same, while the force and direction are completely different. So when operating, you must fully understand the force and manner of stirring, as well as whether the bean's characteristics can adapt, before choosing to use it.

But in the end, all brewing methods actually revolve around adjusting and changing according to the release order of the flavor substances—sour, sweet, bitter. Once you grasp the principle of flavor release, then which brewing method to use is no longer the focus of consideration; the focus is that you know what taste this brewing can bring you, and thus use it with ease. This is also why Front Street has always used the three-stage as its regular brewing method.
