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…]

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…]

The extraction of espresso is extremely sensitive to parameters, with dose, brew ratio, time, flow rate, pressure, and temperature all interconnected; the slightest deviation is magnified exponentially in the flavor. This article systematically sorts out the core logic of various espresso extraction parameters, analyzing the matching of basket capacity and dose, the liquid weight ratio range of 1:1.5 to 1:2.5, the extraction window of 20 to 30 seconds, as well as common issues such as grind size and channeling. It also details operational specifics like weighing the dose, distributing the grounds, tamping, and cleaning. At the end, Front Street Coffee recommends a classic espresso blend to help you consistently produce delicious espresso at home. [more…]

When ordering at a coffee shop, have you ever been confused: if you extract 36ml of espresso from 18g of coffee grounds, should that count as 1 shot or 2 shots? This seemingly simple question actually involves the evolution of measurement standards in the coffee industry. In the early days, 1 shot referred to 30~36ml of coffee liquid extracted from 7~9g of grounds, while today the mainstream approach has changed to extracting 36ml of liquid from 18g of grounds. Is the measurement object the dose of grounds or the volume of liquid? Today, Front Street Coffee will start with the origin of the word "shot" to help you thoroughly sort out the logic for determining single versus double espresso, so you will no longer be confused when ordering or making coffee.

Espresso extraction is far more sensitive than pour-over, and any slight deviation will be magnified exponentially in the flavor. This article systematically breaks down the extraction parameters from six dimensions—dose, brew ratio, extraction time, flow rate, pressure, and temperature—and offers a quick approach to adjusting grind size. In addition, FrontStreet Coffee also provides practical suggestions on operational details such as weighing, distributing, tamping, and cleaning, helping you consistently reproduce a well-balanced espresso in your daily routine.

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 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 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.

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.

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.

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.

The blooming phase in pour-over coffee seems simple, yet the choice of water amount often sparks debate: some insist on twice the coffee dose in water, while some shops advocate that four times the water amount allows for more even degassing. Front Street Coffee conducted a controlled experiment using an Ethiopian Chaka bean, fixing the dose at 15g, the coffee-to-water ratio at 1:15, the water temperature at 92°C, the grind size at a 75%~80% passing rate through a No. 20 sieve, and the total time at 2 minutes, changing only the blooming water amount (30ml vs 60ml), then comparing the differences between the two brews through sensory evaluation and concentration meter measurements. The results showed that the coffee bloomed with twice the water amount had a concentration of 1.54% and an extraction yield of 21.2%, with a richer and more solid flavor; the one bloomed with four times the water amount came in at 1.48% and 20.36%. The article further explains the principle of degassing during blooming, why conventional brewing defaults to twice the water amount, and why special techniques such as the stirring method require more water for blooming, helping you find a blooming strategy that suits you.

For coffee brewing, the coffee-to-water ratio is one of the important factors that need to be considered first. But because it does not need to be adjusted according to the roast level of the coffee beans like water temperature and grinding, we often fix a ratio to brew coffee of all roast levels. For example, Front Street often recommends new [more…]

Front Street Coffee has always emphasized that the extraction parameters for pour-over coffee have a significant impact on the cup, and for espresso the impact is even greater. You should know that factors such as the concentration and extraction time of espresso are more demanding than those of pour-over coffee, and the slightest [more…]

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.

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…]

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…]

It's not hard to see that in almost all moka pot tutorials, we're told to fill the filter basket completely, then screw it tightly to the upper and lower chambers before brewing. In other words, whatever size moka pot you buy, you have to brew that corresponding amount each time. But some people say that sometimes they just want to drink [more…]
