Many people feel they can't taste the flavors when drinking coffee, and despite watching numerous tasting tutorials, they still don't know where to start.

When making a proper espresso, choosing the grind size is often the most critical and most frustrating step. Unlike immersion brewing methods such as pour-over, an espresso machine relies on high temperature and high pressure to complete extraction in an extremely short time, which places demands on coffee grounds fineness and uniformity far beyond those of other brewing methods. If the particles are slightly too fine or too coarse, the flow rate can become abnormal, pushing the flavor toward over-extraction or under-extraction. This article will sort out the extraction principles of espresso from the ground up, explain the suitable grind fineness range, and provide a practical grinding adjustment process and flavor correction approach to help you quickly lock in the right grind setting even when facing unfamiliar beans.

When brewing pour-over coffee, the filter cup actually holds quite a few clues. The size of the dome that the coffee bed puffs up into during the blooming stage, and how well it retains water, can reflect the freshness of the coffee beans and the depth of the roast; whether the coffee bed can be lifted indicates the density of the coffee grounds; the color change of the foam on the surface can help us track the pouring path; and the speed of the drawdown is related to the coarseness of the grind, the density of the coffee bed, and fine particle clogging. As for the deep coffee bed pit that many beginners obsess over, it does not directly equate to a better-tasting cup; it is more just a reflection of the pouring method. In this article, Front Street will break down these readable pieces of information one by one during the brewing process, to help you have a few more bases for judgment when adjusting parameters. [more…]

One of the most frustrating problems in pour-over coffee is water pooling. Once clogging occurs in the final stage of brewing, the coffee's flavor often turns bitter and undrinkable. In fact, before the pouring is finished, there are several time windows where you can predict in advance whether pooling will happen. As long as you master these judgment methods, you can adjust your pouring strategy in time and avoid ending up in a passive position. This article will focus on three key time points—the degree of bloom expansion, the foam performance during pouring after the bloom, and the speed at which the water level drops before the final pour—to explain one by one how to identify the risk of pooling and give corresponding countermeasures. It will also introduce the ultimate solution when all methods fail—flow cutoff—and how to deal with the problems of overly high coffee concentration and missing flavor after flow cutoff. [more…]

In the preparation of espresso, grind size is one of the core variables that determines the success or failure of extraction.
