The Hario V60 Mugen dripper is composed of a detachable 12-blade and base assembly, completely different from the common one-piece drippers. The resin material is heat-resistant and shatterproof, and the blade colors can be freely mixed and matched. It has no cup wall, and the filter paper is supported entirely by the blades, which serve both as a skeleton and as flow guides. In actual testing, the average flow rate after filling with water is about 8ml/s, faster than Kono but slower than the V60's 10ml/s, placing it in the medium-fast range. However, the longer blades raise the pouring height and increase the impact force, making it prone to over-extraction with doses under 20g; it is better suited to 20g or more with an 02-size filter paper. Front Street Coffee also found that removing the blades unlocks a variety of brewing methods, including single-serving setups. [more…]

In the specialty coffee world, "use only freshly ground coffee" is almost treated as gospel, but does this rule hold true in every situation? This article takes an in-depth look at the differences between pre-ground and freshly ground coffee in terms of flavor, aroma, and extraction performance, analyzes why coffee grounds deteriorate faster once exposed to air, and offers practical storage tips such as sealing, vacuuming, and keeping them away from light. At the same time, we'll also explore an easily overlooked fact: if all you have is a poor-quality blade grinder, pre-ground coffee from the shop may actually come out ahead. The article also cites practical insights from Ken Selby, 2018 U.S. Cup Tasters champion, and Alex Choppin, technical specialist at Baratza, to help you make a smarter choice based on your own equipment.

The first step in coffee brewing often begins with grinding. Different extraction methods have different requirements for coffee grounds: a French press needs coarse particles visible to the naked eye, while a Turkish pot requires a grind as fine as flour. At the same weight, the finer the grind, the greater the number of cuts and the larger the surface area, and the more opportunities water has to contact the coffee grounds, so flavor compounds are released faster. To move away from vague descriptions like "as coarse as granulated sugar," Front Street Coffee uses standard sieves to calibrate particle size: generally, pour-over coffee particles are between 600-850 microns; when tested with a 0.85 mm (No. 20) sieve, the pass rate is about 80% for light roasts and about 65-70% for medium-dark roasts. This article will also compare the pass rates of common methods such as cold drip, siphon, moka, American drip filter, cupping, and French press, and introduce the effects of conical burrs, flat burrs, and ghost teeth burrs on grinding results, as well as recommendations for choosing between hand grinders and electric grinders.

Water temperature, grind size, and coffee-to-water ratio are the three key variables that determine coffee extraction. Among them, grind size directly affects the particle size and uniformity of coffee grounds, which in turn influences how efficiently water passes through the coffee bed to extract flavor compounds. The finer the grind, the more tightly packed the coffee bed, the more resistance to water flow, and the longer the extraction time, so strength and extraction yield climb, producing a strong but easily bitter cup; the coarser the grind, the larger the gaps in the coffee bed, the smoother the water flow, and the lower the extraction yield, resulting in a weak, light-bodied coffee. This article uses grind size as the only variable, brewing three groups of coffee—fine, medium, and coarse—with Honduras Lychee Orchid beans, verifying grind size's effect on flavor through strength and extraction yield data, and providing Front Street Coffee's recommended hand-brew grind baseline, while also explaining the differences in characteristics among conical, flat, and ghost-tooth burrs.

For coffee to taste good, freshness is the first essential, and mastering the grind size is the second priority, directly affecting the extraction and the strength of the flavor. In principle, the finer the coffee grounds and the longer the brewing time, the stronger the taste; conversely, the weaker it is. The longer the extraction time, the coarser the beans should be ground, to avoid over-extraction causing bitterness; the shorter the extraction time, the finer the beans should be ground, to avoid under-extraction. Different brewing devices have different requirements for grind size: a French press is suited to coarse grinding, filter paper or a siphon needs slightly finer, and a moka pot, due to different heat sources, has room for flexible adjustment. Espresso relies even more on a precisely constructed dual-burr grinder to brew a thick, authentic Italian flavor. This article will provide a complete analysis of the grinding essentials for each device and visual judgment techniques for espresso. [more…]
