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…]

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…]

Grind size is the key variable that determines the success or failure of a cup of coffee's flavor. Facing the 1 to 10 settings on a grinder, which number actually represents the finest? And how should different brewing methods match grind coarseness? Starting from Front Street Coffee's hands-on experience, this article systematically sorts out the mechanisms by which grind size affects extraction efficiency, compares the grind standards for common brewing methods such as espresso, pour-over, siphon, and French press, and focuses on explaining grind recommendations for medium-light and medium-dark single-origin beans in pour-over scenarios, water temperature pairing, and how to use a 0.85mm No. 20 sieve to precisely calibrate grind size, helping coffee enthusiasts establish clear adjustment logic.

Grind size directly determines the extraction direction of a cup of coffee: too fine a grind easily leads to over-extraction and bitterness, while too coarse a grind may result in under-extraction and a weak, bland flavor. Many grinders on the market mark their settings from 1 to 10, but the corresponding coarseness varies across different models. A smaller number usually means a finer grind, but in practice, you need to judge based on your brewing method. Drawing on the hands-on experience of Front Street Coffee, this article sorts out the grinding ranges for common brewing methods such as espresso, pour-over, siphon, and French press, explains whether medium-light roast and medium-dark roast coffee beans are better suited to a medium-fine or medium-coarse grind for pour-over, and provides specific steps for using a 0.85mm No. 20 sieve to check the passing rate, helping coffee enthusiasts find the right grinding parameters.

If you only have a French press and no pour-over gear, can you still make a satisfying iced coffee? The answer is yes. A French press uses immersion extraction, and with the same beans, the hot coffee it produces is often more balanced and fuller-bodied than pour-over. Borrowing from the Japanese-style iced pour-over approach, you can steep coffee in a smaller amount of hot water to get a concentrated coffee liquid, then pour it over ice to dilute and cool it, making iced coffee. However, diluting with ice lowers the concentration, so it's not advisable to use light-roast beans with pronounced acidity, or the result will taste thin and may develop off-flavors like almond or peanut skin. This article walks through the complete extraction plan using Front Street Strawberry Candy coffee beans, from bean selection to 15 grams of grounds, a 1:8 coffee-to-water ratio, 94°C water temperature, medium-coarse grinding, and the step-by-step process.

Those just starting to explore pour-over coffee often feel at a loss when faced with the wide variety of coffee beans. Front Street Coffee is often asked: what roast level should you actually choose for pour-over? In fact, the roast level directly determines the direction of acidity, bitterness, and sweetness—light roasts lean toward floral and fruity acidity, medium roasts present soft fruit acidity with caramel sweetness, and dark roasts move toward a mellow bitterness like dark chocolate. Besides flavor differences, the roast level also affects bean density and water absorption, which in turn influences the settings for water temperature and grind size. Based on Front Street Coffee's roasting and cupping experience, this article sorts out brewing strategies for different roast levels and breaks down in detail the extraction method for Jamaica Clifton Mount Estate Blue Mountain No. 1, helping everyone brew a balanced, easy-drinking cup of good coffee that is neither bitter nor astringent. [more…]

Blue Mountain coffee is renowned for its balanced profile of sweetness, acidity, and bitterness, with a rich, mellow body, almost no bitterness, and only a slight tang. It is grown in Jamaica's Blue Mountain range at elevations between 910 and 1,700 meters, and the variety is Typica. Thanks to volcanic soil, a humid and foggy climate, and the large day-night temperature difference at high altitude, it develops a clean, subtly fragrant character. To buy authentic Blue Mountain coffee, look for the Jamaican government export certificate and wooden barrel packaging; coffee grown below 910 meters can only be called Jamaica High Mountain coffee or Jamaica Prime coffee. Front Street Coffee recommends brewing it by pour-over, and shares a specific extraction plan using a KONO dripper, 88 to 89 degrees Celsius, and a medium-coarse grind. [more…]
