In the practice of pour-over coffee, the coffee dose is one of the key variables determining the extraction result. Many coffee enthusiasts run into this problem: at the end of a bag of beans there are always a few grams left, too little for a single cup on its own, yet too wasteful to throw away. Based on Front Street Coffee's hands-on testing experience, this article systematically explores the differences between brewing with a small dose of around 7 grams and a conventional 15-gram dose, analyzes the extraction challenges caused by a thinner coffee bed and faster water flow, and offers two sets of adjustment plans for different levels of water-control skill—one that relies on a finer grind combined with a thin stream and three-pour approach, and another that uses a heavy stream and staged raising of the water level to lower the barrier to execution. Whether you are a complete beginner or a pour-over player with some experience, you can find a small-dose strategy that suits you. [more…]

Front Street Coffee shops always stock over thirty varieties of pour-over beans, so it's inevitable that there will be leftover coffee beans that don't get used up. Simply throwing them away is truly a waste, so Front Street Coffee chooses different handling methods based on the amount of remaining grounds: when the amount is around 10g, it can be brewed directly, but the parameters need to be adjusted or a smaller-dose dripper used; if it's less than 6g, it can be topped up by blending with other beans; the coffee beans can also be made into desserts like lemon zest slices, or turned into decorative items such as aromatic bracelets. This article explains in detail the principles and key operational points of each approach, helping you make the most of every single coffee bean. [more…]

Many times, when a bag of coffee beans is nearing its end, there are always less than 15 grams of scattered beans left, which is neither enough for the usual single-serving dose nor enough to blend with other beans to make up the number. If you don't want to waste them, you need to find a way to fully extract the value from these few beans. When the dose is on the low side, the brewed coffee tends to be under-extracted, because the coffee bed becomes thinner, the amount of water poured decreases, and the contact time between hot water and coffee grounds is shortened. If a conical dripper is used, bypass water can also easily dilute the coffee liquid. In response to these difficulties, Front Street shares two approaches in this article to help everyone brew a good cup even with less than 15 grams of coffee beans. [more…]

Small doses in pour-over brewing are often a headache: the coffee bed becomes thin, water tends to channel straight through, and the cup easily turns out thin and insipid. The 30-degree conical dripper from Japan's Tarachine Conical, known in coffee circles as the "V30," was designed specifically for small doses under 15 grams. How does it differ from the classic V60? How do you fold the filter paper? Front Street Coffee tested light and fruity roasts, medium-dark roasts, and three medium-roast beans, comparing the extraction performance of the V30 and the small V60. This article will explain the V30's structural features, filter-folding method, brewing parameters, and suitable roast levels, helping you brew a cup with concentrated flavor and a full body even at small doses.

During holidays and family gatherings, there's always someone hoping the coffee enthusiast will brew a fresh pot on the spot. But when the dose jumps from the usual 15 grams to 30 grams, the same technique tends to cause water to pool at the end of the drawdown, drag out the brew time, and leave the flavor low and muddy. Why does extraction change so much once the dose goes up? Front Street Coffee breaks down the challenges of large-dose pour-over one by one—from dripper model and blooming method to pouring rhythm—and offers adjustment plans for both the 02 and 01 drippers, helping you brew coffee close to your everyday standard even at gatherings with many people. [more…]

The standard dose for pour-over coffee is usually around 15 grams, but when dealing with a rare bean variety or when you just want to taste a sample, can you push the dose down to 5 grams or even lower? Once the dose is reduced, the ratio of hot water to coffee grounds, the extraction time, and the pouring method all change in a chain reaction, and one wrong move can produce a thin or bitter cup. Starting from practical operation, this article sorts out the lower limit of the pour-over coffee dose, analyzes the core difficulties faced by brewing with a small dose, and offers pouring strategies and equipment selection suggestions for extremely small doses such as 5 grams and 8 grams. The article also draws on the store practice of Front Street Coffee to explain the scenarios in which small-dose brewing is suitable and the points to note, helping coffee lovers preserve as much flavor layering as possible while saving beans.

After sharing V60 small-dose brewing techniques, Front Street Coffee received many reader inquiries about how to use the V30 dripper, and some customers also asked in-store about the differences between the V30 and V60. For this reason, Front Street Coffee deliberately placed these two conical drippers side by side for a horizontal comparison. Although their names and shapes are similar, the V60 and V30 come from two different Japanese companies, Hario and Tarachine Conical, respectively, and because of their different cone-angle designs, their extraction effects are also vastly different. This article will analyze the origin of their names, structural differences, and the impact of coffee bed depth on extraction, and will also introduce the brewing method for the V30 dripper in detail, helping coffee enthusiasts understand the characteristics of these two devices more clearly.

Many friends can handle brewing a single serving of coffee with ease, effortlessly producing a delicious pot of coffee. However, when the dose of grounds is doubled and they brew coffee for multiple people, their performance isn't quite as impressive! After going through the whole process, the coffee they brew not only lacks the rich layering it once had, [more…]

How should the coffee dose for pour-over be determined? The common Hario V60 01 dripper is recommended to hold 15–20 grams of coffee grounds, but when there aren't enough beans left or you only want to brew a single cup, using a large dripper with a small dose easily leads to a thin extraction. The 30-degree conical dripper launched by Japan's Tarachine (commonly known as the V30) is designed specifically for small doses of under 15 grams. After getting this transparent resin dripper, Front Street Coffee conducted brewing comparisons using Kenya, Blue Mountain, and three medium-roast beans, and found that the V30 can form a thicker coffee bed with a small dose, extending the extraction path, making the coffee flavor more intense and the mouthfeel fuller. This article documents in detail the filter paper folding method, brewing parameters, and the comparison results with the V60, and offers dose control suggestions, providing a reference for coffee enthusiasts who enjoy small-dose pour-over.

Front Street Coffee has found that many friends always run into this problem when they first start learning coffee brewing: they find that the coffee they brew doesn't taste good, but they can't quite say exactly what's wrong with it. To be honest, if we want to brew a good cup of coffee, besides learning the underlying logic of brewing and mastering the correct extraction parameters, [more…]

When brewing coffee, under-extraction or over-extraction will both bring unpleasant flavors. Starting from the golden cup extraction standard, this article explains the origin of the 18%–22% extraction yield, and details how to judge whether coffee is under-extracted or over-extracted by tasting sour, sweet, bitter, and other flavor expressions. At the same time, for common extraction problems in home brewing, it provides practical suggestions for adjusting grind size, water temperature, and brewing rhythm, helping coffee lovers easily brew a balanced and tasty cup.

When making espresso, extraction occasionally ends prematurely due to an accidental touch or oversight. Some people wonder: since it wasn't extracted enough, can we just press the button again to continue extracting, like with pour-over? Front Street used the Warm Sun blend to conduct a comparative experiment, testing three scenarios: normal extraction, extraction resumed after being interrupted midway, and extraction resumed after being interrupted near the end. The results showed that after restarting, the flow rate was extremely fast, the color was pale, and the flavor was noticeably thin; even with further extraction, it was difficult to fully extract the remaining substances. This article will start from the principle of pressurized extraction in espresso machines to explain why the same puck is not suitable for secondary extraction, and what the more reliable approach is when an accidental interruption occurs. [more…]

If you mistakenly press the stop button during espresso extraction before reaching the target yield, can you simply press it again to continue extraction? This article compares three espressos—normal extraction, mid-extraction stop-start, and stop-start near the final phase—to analyze how segmented extraction affects the color, flavor, and concentration of the coffee liquid. Front Street Coffee uses the Warm Sun blend, testing with 20g of grounds extracted to 40ml at a 1:2 brew ratio, to reveal why under pressurized extraction, changes in the puck structure cause an overly fast flow rate and under-extraction during a second extraction, along with operational recommendations. [more…]

When brewing coffee, unpleasant flavors often come down to two situations: under-extraction or over-extraction. Front Street Coffee has found that many beginners can taste that something is off with their coffee but can't pinpoint the problem. This article starts with the definition of the Golden Cup standard, explaining the reference range of an 18%–22% extraction yield, while also pointing out that the Golden Cup is not an absolute standard and that coffee bean quality can affect the results. It then details the three main signs of under-extraction—watery flavor, thin body, and sharp sourness, astringency, and saltiness—as well as the characteristics of over-extraction, such as pronounced bitterness, dryness, and woody off-flavors. Finally, it offers a practical adjustment plan that uses grind size as the variable while keeping water temperature, time, and water amount fixed, helping everyone quickly find the parameters that suit them.

Judging whether a cup of coffee tastes good varies from person to person, but when it comes to the defective flavors caused by extraction problems, people often reach a consensus. This article, from the perspective of Front Street, introduces the specific taste manifestations of under-extraction and over-extraction. When under-extracted, coffee presents sharp acidity, noticeable saltiness, a lacking finish, and thin flavor; over-extraction, on the other hand, allows bitterness to greatly suppress other flavors. The article also specifically reminds us not to rigidly adhere to the golden cup extraction numbers, because bean quality and processing methods can cause deviations from theory, and ultimately the real sensation on the palate should be the basis for judgment.
