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.

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…]

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. [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. [more…]

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.

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.
