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.

This article will answer these questions from three perspectives—cost, stability, and crema—and systematically share the four core points of blending coffee beans: from bean selection, removing defects, understanding characteristics, to mastering roasting attributes, helping coffee enthusiasts build a clear espresso blending logic.

Many coffee enthusiasts are still unfamiliar with Lungo, and may even confuse it with Long Black. In fact, Lungo, like Ristretto, belongs to the espresso family—both are made directly with an espresso machine without adding any other ingredients. The difference lies in the amount of extracted liquid: a standard espresso uses 20g of grounds to extract about 40ml, Ristretto reduces the liquid to about 30ml to increase concentration, while Lungo extends the extraction time and increases the liquid to about 100ml, with concentration decreasing accordingly. Lungo was born in an era when early espresso machines had pressure of only 1.5~3 bar, and at that time the only way to compensate for insufficient pressure was to extend the extraction. Today, espresso machines are much more efficient, and traditional Lungo tends to be over-bitter, but by adjusting the parameters, it is still possible to make a version that suits modern tastes. In this article, Front Street Coffee will walk you through the origins of Lungo, its differences from Long Black and Ristretto, and how to extract a modern Lungo that isn't bitter. [more…]
