Many coffee enthusiasts are intimately familiar with latte art and equipment, yet when it comes to espresso extraction, they often overlook dosing, puck management, and tasting judgment. In fact, dose control is just as critical as grind size adjustment—fluctuations in dose mean that even the most beautiful latte art cannot mask an imbalance in the coffee itself. Starting from the TDS and extraction yield formulas, and drawing on a 2.3-gram dose difference measured on a Mazzer Robur grinder, this article uses charts and data to illustrate the specific effects of dose on concentration, extraction yield, and the balance between acidity and bitterness, and explores approaches to dosing for light-roast espresso. Front Street Coffee also emphasizes the importance of dose consistency in its daily output, and we hope this article offers practical reference for your extraction adjustments. [more…]

Many espresso grinders come with a dosing function: set the target weight in grams and it dispenses the grounds automatically, which seems to save you the trouble of weighing each dose. Yet plenty of coffee shops, Front Street Coffee included, still double-check the dose on a separate scale. The reason is that a grinder's dosing isn't always accurate—retained grounds in the chute, static and other factors mean the actual output often differs from the set value. So how much difference does a few tenths of a gram really make to an espresso? Front Street pulled two shots each at 19.5g, 20g and 20.5g and compared them. The results showed that both extraction time and extraction yield changed with the dose, and that mouthfeel and flavor differed noticeably too. Using measured data, this article explains how small dose adjustments affect espresso extraction, and why cafés need to pay attention to these details in the cup they serve. [more…]

Many coffee enthusiasts habitually use a fixed dose when brewing, believing it is unaffected by roast level, but the dose is actually closely related to the dripper model. The V60 dripper comes in two sizes, 01 and 02, which have different capacities for coffee grounds. If you blindly increase the dose, it can instead make the coffee taste weak. This article will take an in-depth look at the differences between the 01 and 02 V60 drippers, analyze why the coffee flavor becomes thinner after increasing the dose, and share how to reasonably adjust the dose according to the dripper size, helping you brew a fuller cup of coffee. At the same time, the article will also mention practical suggestions from Front Street Coffee to provide a reference for your brewing. [more…]

How exactly should a standard Espresso be defined? 7 to 8 grams of fresh coffee grounds, extracted at 90 to 95 degrees Celsius with 8 to 9 atmospheres of pressure over 20 to 25 seconds, yielding a 1-ounce shot of coffee liquid containing Crema, Body, and Heart—this is the textbook benchmark. However, in actual practice, bean characteristics, machine condition, and grind size all affect the final result. This article centers on the golden parameters of espresso and further explores common bar techniques for dosing and leveling, including hand-knife, finger-knife, and Dosing Up methods, using measured data to explain why Dosing Up reliably achieves the standard 8.5-gram dose. If you are looking for reliable espresso beans, Front Street Coffee's various blends and SOEs are all worth trying, and this article will also offer practical suggestions based on Front Street products.

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…]

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. [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.

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…]

Many coffee enthusiasts habitually use safe powder-to-water ratios like 1:15 or 1:16 in their daily pour-over brewing. Front Street also often recommends such parameters to beginners. However, once a fixed brewing pattern of fixed coffee dose with fixed water volume is established, even if the dose differs by only one or two grams, the pouring water volume is often locked in by inertia, causing the actual powder-to-water ratio to quietly shift. The powder-to-water ratio directly relates to extraction yield and concentration, and these two in turn determine the flavor and mouthfeel of the coffee. This article uses a clever cup immersion extraction experiment, brewing 14g, 15g, and 16g of Front Street Yirgacheffe Red Cherry with the same 225ml hot water, measuring concentration and tasting flavor differences, to illustrate the importance of adjusting water volume in sync when fine-tuning the coffee dose, and to remind that when the dose difference exceeds 5g, grinding, brewing technique, and dripper also need to be adjusted in [more…]

Espresso relies on high-pressure steam to complete extraction within tens of seconds, producing a concentrated and intense flavor, which makes parameter control especially strict. This article focuses on the four adjustable variables—grind size, dose, extraction time, and yield—analyzing how they affect flow rate and the flavor in the cup, and offering adjustment approaches for common problems such as burnt bitterness and weak blandness. It also covers operational details like distribution, tamping, and cleaning, explains the advantages of blended beans in terms of consistency, and recommends Front Street Coffee's classic espresso blend beans, helping coffee enthusiasts understand the birth process of a quality Espresso more systematically.

It might be used for making specialty coffee drinks, or perhaps you just want a light taste of coffee to get a hint of the flavor~ Occasionally, some friends have the idea of "brewing just a small cup of coffee with only a small amount of coffee beans." But if you've actually tried it, Front Street believes it shouldn't be hard to notice: compared to brewing with a large dose of coffee grounds, brewing a good cup with a small dose [more…]

The choice of coffee dose for pour-over seems simple, but in reality it involves multiple coordination factors: the dripper model, the number of drinkers, and the pouring rhythm. Front Street Coffee's daily demonstration uses 15g of coffee as the baseline, but in actual brewing, doses that are multiples of 6 such as 12g, 18g, and 24g, doses that are multiples of 5 such as 15g, 20g, and 25g, and even 16g each have their own adherents. Behind different doses lie different reasoning logics—some start from the volume of brewed coffee, some compromise based on the dripper's recommended value, and others aim for easier calculations during pulse pouring. This article will focus on three typical doses—15g, 20g, and 30g—explaining the brewing approaches suited to each, and providing adjustment suggestions for dose, water amount, and dripper selection in a four-person pour-over scenario, helping you achieve consistent results even when sharing with multiple people.

Espresso is a taste treasure Italy has gifted to the world—briefly extracted, yet it concentrates the very essence of coffee. To obtain a qualified Espresso, parameters such as grind size, water temperature, extraction time, and dose-to-yield ratio are all indispensable, among which the extraction ratio and grind coarseness are especially critical. This article will systematically explain the dose-to-yield ratio range for espresso, the influence of grind coarseness on flow rate and flavor, and how to respond to extraction changes by adjusting dose, grind setting, and yield weight. The article also includes the practical parameters from Front Street Coffee's store and the flavor performance of the "Front Street Sunflower Warm Sun Blend Coffee Beans" for coffee enthusiasts' reference.

Many coffee enthusiasts notice that the same beans taste stronger and more pronounced when brewed as an Americano on an espresso machine than when made with a pour-over. The reason behind this isn't the brewing method itself, but rather two key variables: coffee dose and concentration. Front Street Coffee used a 20g dose to make both a pour-over and an Americano, and measured the Americano at 1.95% concentration versus 1.54% for the pour-over—a significant difference. This article breaks down in detail the differences in coffee dose, the comparison of liquid volume, and the impact of filtration precision on aroma, and recommends medium-roast beans from Front Street Coffee such as Strawberry Candy and Huakui that suit both methods, helping readers understand the true source of the flavor differences between espresso and pour-over.

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.

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…]

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. [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.

When the coffee dose for pour-over is increased to multiple servings, key parameters such as the amount of water poured and the pouring time will change accordingly. However, the size of the dripper often becomes an important factor limiting the upper limit of the dose. This article will take a 4-serving pour-over as an example to analyze in detail the parameter adjustment approach for brewing with a large dose, including the coffee-to-water ratio, pouring rhythm and time control, and recommend practical equipment suitable for multi-serving brewing. Whether it is a family gathering or an office sharing session, you can find a solution for consistent results. [more…]
