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 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…]

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 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…]

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.

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.

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.

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…]

Espresso is a taste treasure Italy has gifted to the world—briefly extracted, yet it concentrates the very essence of coffee.

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…]

The extraction of espresso may seem simple, but in reality it hides quite a few intricacies. When many coffee enthusiasts learn to make Espresso, they encounter a classic set of parameters: 14 grams of coffee grounds, extracting 50 milliliters, in 25 seconds. However, in actual practice, not many people truly extract according to this standard, often because of poor past experiences and a habit of increasing the dose to achieve a stronger flavor. In fact, extracting 50 milliliters from 14 grams is precisely an ideal baseline for testing a coffee bean's flavor performance, allowing for a relatively complete extraction of the coffee's balanced taste. On this basis, increasing the dose and adjusting the concentration according to personal preference is the more scientific approach. This article will focus on key steps such as grind setting, tamping pressure, and extraction observation, breaking down in detail the essentials of making espresso to help you produce a cup of balanced-flavor Espresso.

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.
