Many coffee enthusiasts have found during brewing that simply adding a little more coffee grounds causes a noticeable decline in the resulting flavor. The reason behind this often lies in the amount of grounds exceeding the reasonable capacity of the current dripper, while the brewing technique has not been adjusted accordingly. This article will focus on the suitable grounds amounts for the two common dripper models, 01 and 02, analyzing the specific effects of too much or too little coffee on extraction uniformity, flow rate, and the final flavor. At the same time, for scenarios where you only have a small dripper on hand but need to brew a large amount of coffee, it provides a complete solution including coarsening the grind size, slightly adjusting the water temperature, and pouring techniques, and offers practical reference suggestions based on Front Street Coffee's standard parameters.

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.

Japanese-style pour-over often uses a large dose of 20g or more—what extraction logic lies behind this? Starting from the characteristics of the dark-roasted beans favored by the Japanese, this article explains why they dislike bitterness, why they choose a coarse grind, and how a large dose slows the flow and increases concentration by thickening the coffee bed, ultimately forming a "high concentration, low extraction" style. The article also compares the differences between the Japanese-style coffee-to-liquid ratio and the conventional coffee-to-water ratio, and points out how a long extraction time, combined with a large dose, brings out caramel aroma and a highly sweet, lingering finish. If you are interested in the unique methods of Japanese brewing, or want to understand the concept of high concentration, low extraction discussed by Front Street Coffee, this article will give you clear answers.

Many coffee enthusiasts, once accustomed to the rhythm of brewing a single serving of pour-over, often find that flavors turn out vastly different from their daily results when they attempt to brew a large batch of four servings at once. The increase in coffee dose brings not only a change in water volume, but also systematic adjustments involving dripper capacity, pouring technique, grind size, and even extraction time. Front Street Coffee frequently receives similar questions: how should 30 grams of coffee be brewed to taste good? This article will provide a complete overview of the practical key points for large-dose pour-over, from dripper matching, grind size setting, and blooming strategy to the logic of staged pouring, helping you consistently present a clean and well-layered coffee flavor even when sharing among multiple people.

Pour-over coffee enthusiasts often run into this dilemma: they only have a 01 single-cup V60 dripper on hand, yet need to brew a multi-serving batch with 30 grams of coffee at once. Doubling the coffee dose is easy, but scaling up the water volume accordingly will exceed the dripper's capacity, leading to uncontrolled extraction. Does that really mean a small dripper can't handle a large dose? Not at all. Front Street successfully brewed 30 grams of Front Street Granja Geisha with a 01 V60 by adjusting the grind size, pouring method, and staged strategy, achieving a 20.33% extraction yield, with a balanced, sweet flavor where apricot, berry, citrus, and oolong tea notes are clearly distinguishable. This article shares this fully tested set of parameters and operating steps with anyone who has the same need. [more…]

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…]

Front Street Coffee uses a standard dose of 15 grams of coffee per serving, so when sharing brewing methods, 15 grams is always used as the demonstration standard. However, the dose used to brew coffee varies widely. Based on Front Street Coffee's observations, the most common doses are multiples of 6—12 grams, 18 grams, and 24 grams—and these are mostly used to make a single serving of 120 [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.

When making espresso, the puck sometimes sticks to the dispersion screen of the group head. What exactly causes this? And does it affect the flavor of the coffee? This article starts with three common causes and analyzes them one by one: too much coffee grounds, failing to remove the portafilter in time after extraction, and the puck being knocked loose. Front Street will also draw on its own practical experience to explain the possible burnt and bitter taste issues that can arise when the puck comes into contact with the dispersion screen, as well as the impact of channeling on espresso performance, helping you judge in your daily service when there is no need to worry and when you need to adjust parameters.

Front Street Coffee's pour-over tutorials have long been based on a single-serving standard of 15g of coffee and a 200ml cup, but many enthusiasts are no longer satisfied with brewing just one cup and have begun trying to make two or three cups at once. Once the dose is doubled to 30g, the small 01 dripper can no longer handle it, and a V60 02 large dripper must be used instead. Increasing the dose is far from simply adding more coffee and water; a thicker coffee bed slows the flow rate, and as the extraction time lengthens, bitterness follows. Using the Sidra coffee beans as an example, Front Street Coffee starts with two variables—grind size and pouring stream—to make fine adjustments, compressing the total time from 2 minutes 53 seconds to 2 minutes 30 seconds so that the 30g brew comes close in flavor to a single-cup brew. This article fully records the parameter differences before and after the adjustment and the reasoning behind them, and also answers the question of whether the 01 dripper can be used to brew a large dose when no 02 dripper is available. [more…]

Front Street Coffee's pour-over tutorials have long been based on a single-serving standard of 15g of coffee and 200ml of water, but when you need to brew 2 to 3 cups at once, the No. 01 small dripper simply can't handle the job. This article centers on a hands-on test of brewing with 30g of coffee in a V60 02 large dripper, starting with a 1:15 coffee-to-water ratio, 91℃ water temperature, and a three-pour technique, which revealed that the extraction time was too long and produced bitterness. The parameters were then revised by coarsening the grind and increasing the pouring speed, ultimately bringing the extraction time under 2 minutes 30 seconds, with the flavor matching that of a single serving. The article also retains recommendations for several Front Street Coffee beans and answers the question of whether the No. 01 dripper can brew a large dose when no No. 02 dripper is available, making it suitable as a reference for enthusiasts who have already mastered basic pour-over and want to advance to brewing for multiple people.

The V60#01 dripper is typically suited for 1 to 2 servings, with 15 to 20 grams of coffee being its optimal working range. But in reality, when drinking alone and not wanting too much, people reduce the dose, and when sharing with friends, they increase it. So, when brewing different doses in the same dripper, do the parameters really need to be changed? Front Street Coffee conducted three sets of comparative experiments using Ethiopian Yirgacheffe natural Red Cherry, with doses of 10 grams, 15 grams, and 25 grams, a fixed water temperature of 90°C, a 1:15 coffee-to-water ratio, medium-fine grind (80% passing through a Chinese standard No. 20 sieve), and circular pouring. The results showed that with a smaller dose, the flavor tends to be thin, while with too large a dose, bitterness may appear and the liquid level may awkwardly approach the rim of the cup. This article will break down the three brewing recipes one by one, their flavor performance, and the adjustment approaches for 10 grams and 25 grams, to help you find a more reasonable extraction method in this small dripper.

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.

Although a single shot of espresso yields only a small amount, it is the foundation of countless coffee drinks such as Americano and latte. Extracting a good Espresso requires precisely controlling multiple variables within a few dozen seconds, including dose, yield, time, and grind size. Drawing on Front Street Coffee's hands-on experience, this article breaks down the core factors that influence espresso flavor, explains the 1:2 brew ratio reference standard, and shows how adjusting parameters can bring out the ideal whisky aroma, vanilla cream, and berry-like acidity in coffee, helping coffee lovers build a clear framework for dialing in.

Espresso extraction has never been something that can be solved with a fixed formula. The freshness of the coffee beans, the grind size, the brand and model of the espresso machine, the extraction pressure, and the stability of the water temperature—every one of these variables will cause the final cup's flavor to deviate. Precisely for this reason, in its educational articles Front Street Coffee rarely gives an exact extraction time figure the way it does for pour-over. This article will start from the dimensions of dose, coffee-to-water ratio, extraction time, flow rate, pressure, and water temperature, systematically sorting out how to customize a suitable espresso extraction plan for the blend in your hands, and will also introduce the methods for measuring and calculating espresso concentration and extraction yield, helping you find your own cup of good coffee within the Golden Cup reference range.

Friends who enjoy Japanese-style dark roast coffee often notice a pattern: a large dose of grounds with a small amount of water produces a cup that is rich but not bitter. This approach has a professional name today—high concentration, low extraction. It is both a summary of past Japanese brewing traditions and an effective way to avoid the bitterness of dark-roasted beans. This article will start from the principles, explaining why Japanese brewing favors a large dose and a low extraction rate, and how doing so simultaneously enhances body and flavor intensity. Then Front Street will use PWN Golden Mandheling as an example to share a set of iced high-concentration, low-extraction practical parameters, including dose, ratio, grind, water temperature, and staged pouring, to help you easily recreate a classic dark roast flavor.

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…]

When pulling espresso, you sometimes remove the portafilter and find a large amount of hot water left in the basket, with the puck wet, even loose and misshapen. This phenomenon not only affects consistency in the cup but also makes it hard to identify the root cause. Starting from the principles of espresso extraction and pressure release, this article systematically breaks down the three common causes of water pooling in the basket: grinding too fine, which impedes the flow of hot water through the coffee bed; using too small a dose, which leaves too much distance between the puck and the shower screen; and insufficient pressure on home machines, which weakens the back-suction effect. It also offers Front Street Coffee's adjustment suggestions to help coffee enthusiasts quickly pinpoint the problem and improve extraction flow rate and puck condition. [more…]

The essence of Americano is the combination of espresso and water, so the quality of a cup of Americano depends on the extraction quality of the espresso. However, adjusting espresso parameters often consumes a large amount of beans and time, and even professional baristas need multiple attempts when facing new beans. This article will systematically explain how to quickly and economically find suitable espresso parameters, analyze the adjustment logic of the three major variables—grind size, dose, and yield—and share pairing suggestions for Front Street specialty blend coffee beans. At the same time, the article will also introduce the benefits of black coffee and healthy drinking methods, helping coffee lovers enjoy deliciousness while also taking care of their health. [more…]

Espresso, with its high-pressure rapid extraction, serves as the base for lattes, cappuccinos, and other specialty coffee drinks. It uses a large dose of coffee and yields a small volume of liquid, with a concentration far higher than pour-over and other drip coffees. This article explores the extraction principles, coffee-to-water ratios, and flavor characteristics of espresso, and uses a Front Street Yirgacheffe Gudingding Cooperative coffee bean as an example to compare the extraction parameters and taste differences between pour-over and espresso. It also introduces the four blended coffee beans that Front Street has specially crafted for espresso, as well as reference parameters for single and double shots served in stores. Finally, it provides practical methods for adjusting the water-to-coffee ratio and grind size to help you find the balance between acidity and bitterness, and craft a cup of espresso with stable flavor.
