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 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.

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. [more…]

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.

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.

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…]

Many people pursue sweetness in coffee because sweetness promotes dopamine secretion and brings a pleasurable experience. But sweetness in coffee does not exist independently; it is presented through the balance between acidity and bitterness: the sweetness of light-roasted beans is hidden in the sweet-and-sour fruit profile of high acidity and low bitterness, while the sweetness of dark-roasted beans is integrated into the caramel and maple syrup flavors of low acidity and high bitterness. This article first recommends four Front Street Coffee beans with strong sweetness—Panama Boquete Geisha, Mozart, Queen's Estate, and Golden Mandheling—and then provides sweetness-brewing approaches for medium-light roasts and medium-dark roasts respectively: light-roasted beans can release mid-palate sweetness by increasing water temperature, sieving out coarse grounds, and adjusting the pouring technique; dark-roasted beans use a high-strength, low-extraction strategy, paired with a slow-flow dripper and gentle pouring, to reduce the release of bitterness. Whether you are a beginner or an advanced player, you can find actionable sweetness-brewing solutions here. [more…]
