For friends who enjoy espresso, the purpose of adjusting parameters after startup is often not for the espresso itself, but to see whether the fancy coffee drinks made with it as a base actually taste good—for example, whether the Americano with added water is fragrant enough and whether it will be bitter, whether the latte paired with milk is strong enough, whether it is mellow, and so on. Therefore, espresso [more…]

Although latte coffee is everywhere, actually making a delicious latte is not simple. Variables such as coffee bean flavor, milk quality, and extraction parameters all directly affect the final taste.

The extraction standards for espresso have always been a core topic of interest for coffee enthusiasts. The SCAA once defined it as 9-10 atmospheres of pressure, 7-9 grams of coffee grounds, water temperature of 88-92°C, and extraction of 45ml in 22-28 seconds, but today the actual operating parameters of specialty coffee shops have clearly diverged from this. Starting from the practical experience of Front Street Coffee, this article reviews the evolution of espresso extraction parameters along with roasting trends and equipment technology, analyzes the influence of the five major variables—dose, water temperature, time, pressure, and grind size—and introduces the flavor performance of Front Street Sunflower Warm Sun blend beans as well as the correct way to taste espresso.

Espresso, with its golden crema and rich, full-bodied flavor, has become a favorite among many coffee lovers. Unlike pour-over, it uses steam pressure to force hot water quickly through a puck of coffee grounds, extracting a concentrated liquid in a short time. Behind this seemingly simple operation, parameters such as dose, yield, time, and grind size all influence one another, and even a slight change can affect what ends up in the cup. This article will systematically outline the extraction principles of espresso, analyze the relationship between brew ratio, extraction time, and grind coarseness, and, using the examples of Front Street Coffee's Sunflower Warm Sun Blend and Classic Italian Blend, explain how to adjust parameters based on flavor feedback, helping you consistently make a delicious espresso at home.

Espresso is Italy's gift to the world of coffee, renowned for its short extraction time and intense flavor. But pulling a good shot of espresso is no easy task—grind size, water temperature, extraction time, and the coffee-to-water ratio all require precise calibration. This article focuses on the extraction ratio as its core variable, laying out the logic behind the dose-to-yield ratio, the effect of grind coarseness on flow rate and flavor, and how to respond to changes in weather and bean conditions by adjusting dose, grind size, and yield. It also explains how roast level affects extraction stability, and includes the flavor profiles and reference extraction recipes for several of Front Street's espresso blends, helping coffee enthusiasts understand the principles behind the parameters.

Espresso extraction is not something that can be mastered 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 all cause the same bean to present completely different flavors in different hands. This article starts from the dimensions of dose, brew ratio, extraction time, flow rate, pressure, and water temperature, systematically explaining how to customize a suitable espresso extraction plan for the blend of coffee beans you have on hand. It also introduces how to troubleshoot and adjust one by one when the flow rate is abnormal, and how to use a concentration tester to calculate the extraction yield and determine whether it falls within the golden cup range. The article uses the "Warm Sun" blend from Front Street Coffee as an example, providing specific parameter references, and is suitable for coffee enthusiasts who wish to refine their espresso skills.
