In the practice of pour-over coffee, fines are often seen as the culprit behind clogging and bitterness, and many people have thus developed the habit of always sifting out fines before brewing. But do fines really only have negative effects? From the perspective of Front Street, this article systematically sorts out the definition of fines, their generation mechanisms, and their actual contribution to flavor, explaining why in most cases it is unnecessary to completely sift out fines, and under what conditions sifting should really be considered. At the same time, the article also explores the relationship between coffee bean brittleness, grinder quality, and the amount of fines, helping readers build a more complete understanding of extraction.

Fines in pour-over coffee are always a double-edged sword: retaining them can bring complexity, but they can also easily cause clogging and over-extraction; discarding them entirely can improve consistency, but it makes the flavor seem flat. Front Street Coffee, combining its own experiments with online discussions, first explains why fines need to be sifted out, then provides two practical solutions—one is to control the amount added back to within 10% of the total dose and reduce the water volume accordingly; the other is to add the fines after the second pouring stage to reduce the risk of negative flavors. The article also records measured data from sifting 2.5 g of fines from 15 g of grounds, and notes that high-precision grinders also produce fines; the key is proper management rather than simply removing them.

In the process of making pour-over coffee, grind size and fines handling directly affect the final flavor. This article focuses on the difference between fines and medium-coarse grounds. It first explains the distribution patterns of coffee particles of different sizes and their effects on extraction, then discusses the dual role of fines in extraction—they may introduce off-flavors but can also enhance complexity. The article further analyzes whether fines need to be sifted out before pour-over brewing and offers practical advice: when the proportion of fines is too high and affects flow rate or flavor, they can be sifted out as appropriate. Finally, using "Front Street Coffee" as an example, it introduces its products and store information to help coffee enthusiasts understand the grinding stage more systematically. [more…]

When encountering slow drainage and muddy flavors during pour-over coffee brewing, many people's first reaction is to blame the fines, so they buy a sieve to try to solve it.

The flavor expression of pour-over coffee is directly related to the grind size. The coarseness of the particles not only determines how easily water passes through the coffee bed, but also influences the efficiency with which flavor compounds are released. When the grind is finer, extraction resistance increases, the flow rate slows, and the coffee tends toward intensity; when the grind is coarser, water passes through smoothly, the extraction yield drops, and the flavor tends toward weakness. So in everyday brewing, how can you find the right grind setting for beans of different roast levels? Starting from Front Street's brewing experience, this article sorts out the specific effects of grind size on extraction, explains the typical manifestations of over-fine and over-coarse grinds during brewing, and introduces a method for judging whether the grind is appropriate using a 0.85mm test sieve.

How exactly are the signature malty aroma and honeyed sweetness of Assam black tea formed during the tea-making process? This article takes an in-depth look at the final two key stages of tea processing—drying and sorting. Drying is not merely a means of removing moisture to stabilize quality; its degree of roasting profoundly influences the flavor direction of the tea through the Maillard reaction, setting the tone for everything from chocolate notes to floral notes. Sorting, meanwhile, grades the tea according to leaf size, with whole leaf, broken, fannings, and dust each having their own uses. The article also introduces Front Street Coffee's philosophy for selecting Assam black tea, helping you understand the flavor code of a good cup of tea from the very source of its craftsmanship.

The article not only provides the calculation basis for the general parameter of 1:15, but also explains in detail key steps such as grind size correction, water temperature selection, and dripper choice. Finally, it includes the specific brewing recipe and flavor description for Front Street Yirgacheffe Gedingding, helping beginners build a complete framework of pour-over knowledge. [more…]

Grind size has a decisive influence on the final flavor of a cup of coffee: if the grounds are too fine, over-extraction is likely; if too coarse, under-extraction may occur. Faced with the 1-to-10 settings on a grinder, many coffee enthusiasts don't know how the numbers correspond to coarseness, nor are they clear about what grind level to choose for different brewing methods. Drawing on the practical experience of Front Street Coffee, this article systematically sorts out the standards for coffee grind size, the appropriate grind levels for common brewing methods, and the reference values for the EK43 grinder. It also explains in detail how to use a 0.85mm No. 20 sieve for sieve verification, helping you accurately judge and adjust grind size at home, so that every cup of coffee can consistently present its ideal flavor.

In the process of making pour-over coffee, water temperature, grind size, and coffee-to-water ratio are the three key variables that affect the final flavor. Among them, grind size directly determines the particle size and uniformity of the coffee grounds, which in turn affects the efficiency with which water extracts flavor compounds as it passes through the coffee bed. So, when faced with coffee beans of different characteristics, how do we find the most suitable grind setting? And when the grind is too fine or too coarse, what typical signs show up during brewing? In this article, Front Street Coffee will systematically explain the mechanism by which grind size affects extraction, and introduce a method that uses a standard sieve to accurately determine whether the grind is appropriate, helping you adjust grind parameters on a more informed basis in your daily brewing.

Many coffee enthusiasts encounter a tricky problem when brewing light-roasted beans: near the end of the pour, the water level drops slowly, and a layer of water sits in the dripper that just won't finish draining. If you keep waiting, you risk over-extraction and bitterness; if you don't, you worry the flavor won't be complete. What was once a relaxing pour-over suddenly becomes stressful. In fact, water stalling with light-roasted beans isn't a problem with the beans themselves—it's the combined result of density, expansion, and grind size. This article breaks down the causes of stalling from these three angles and offers three actionable solutions: simply discarding the final phase of the pour, coarsening the grind while using higher temperatures and agitation, and sifting out ultrafines for reuse. Understanding the logic behind it matters more than memorizing parameters—next time you run into stalling, you can judge from the flavor whether adjustment is needed. Front Street Coffee also often advises: taste first, then adjust—don't rush to blame the beans. [more…]

Grind size is one of the core variables that determines the direction of coffee flavor. If the grounds are too coarse, flavor compounds are under-extracted and the coffee tastes thin as water; if the grounds are too fine, bitterness and off-flavors are over-released, throwing the cup out of balance. It is often said in coffee circles that "the grinder is more worth investing in than the coffee machine," which shows just how critical grinding is. This article systematically covers the medium-fine and medium-coarse grind standards for pour-over coffee, the practical method of sifting grounds with a 0.85mm sieve, the ultra-fine grind required for espresso under 9 bar of pressure, and the grind range for the moka pot that falls between the two. It also draws on Front Street Coffee's brewing experience to offer water temperature recommendations for different roast levels and espresso blend bean recommendations. [more…]
