There is no unified quantitative standard for coffee grinding, so enthusiasts often use everyday ingredients as analogies to quickly convey the concept of particle size. Common reference points like fine granulated sugar, coarse granulated sugar, sea salt, fine salt, and flour each correspond to different brewing methods and roast levels. This article goes through the particle size characteristics and suitable scenarios for each of these analogous grinds one by one: fine granulated sugar is mostly used for light-roast pour-over, coarse granulated sugar suits medium-dark roast beans, sea salt-like texture is suitable for immersion extraction methods like the French press, fine salt-like texture serves the fast-paced extraction of the moka pot, and flour-like texture is divided into two categories: espresso and Turkish coffee. The grind size described by each analogy is a range, not a single fixed value, and understanding this point helps with more flexible grind adjustment. [more…]

In coffee brewing, the coarseness of the grind directly affects the extraction result, yet how to describe and judge grind size has long lacked a unified standard. Some people use fine granulated sugar as an analogy, some rely on the grinder's settings, and others, like Front Street Coffee, quantify it through sieving rate. Each of these methods has its pros and cons, but the ultimate goal is the same: to help us adjust the grind into the right range before brewing. This article will systematically sort through three common ways of expressing grind size—the setting reference method, the visual analogy method, and the sieve calibration method—analyze their respective limitations and applicable scenarios, and explain in detail the No. 20 standard sieve procedure used by Front Street Coffee, helping you find the most suitable grind parameters with fewer beans.

Huakui coffee has maintained a high level of popularity in the coffee community thanks to its excellent value for money and its naming method that is updated and iterated every year. Front Street also often includes it in its promotional bean list, and many friends ask customer service after placing an order: what can be done to best showcase Huakui's flavor? In fact, different extraction methods each have their own characteristics, and there is no absolute ranking of better or worse. Everyone might as well try several methods and find the cup that suits their own taste best. In this article, Front Street will systematically share the specific parameters and operational details for making Huakui using four methods: pour-over, pour-over iced coffee, immersion, and cold brew, including key information such as coffee dose, coffee-to-water ratio, water temperature, grind size, and extraction time, to help you more easily recreate Huakui's floral and fruity aroma at home.

Many coffee enthusiasts have experienced this confusion: why does the same bean taste different every time it's brewed? Occasionally a stunning cup of coffee is brewed, but it's hard to reproduce afterwards, so some people attribute coffee extraction to "metaphysics." But in fact, extraction is a quantifiable, reproducible scientific process. Water acts as a solvent, dissolving the flavor substances from the coffee grounds, while parameters such as grind size, water temperature, time, and coffee-to-water ratio all directly affect extraction efficiency, and thereby determine the final flavor in the cup. Taking Ethiopia Huakui as an example, Front Street uses 15g of grounds, a 1:15 coffee-to-water ratio, caster sugar grind size, and a two-minute three-pour brewing method to consistently obtain a coffee with balanced acidity and sweetness, carrying citrus, strawberry, and creamy floral aromas. This article will systematically explain how to achieve flavor stability and targeted adjustments by recording and controlling parameters, and explain the scientific logic behind the differences in dissolution rates of sourness, sweetness, bitterness, and saltiness.

Many people new to pour-over coffee tend to focus on pouring techniques, but Front Street believes that what really determines whether a cup of coffee tastes good is whether the extraction parameters are reasonable. The differences between single-pour, three-stage, and 4:6 methods are essentially differences in parameter configuration. This article starts from Front Street's practical experience, first sorting out the underlying logic of grind size, water temperature, and ratio, then sharing a simplified approach that requires almost no water-control skill—paired with a cake filter cup, you simply bloom and then pour all the remaining hot water in one go, reliably producing a coffee with balanced sweetness and standout sweetness. Using Front Street Ethiopia Huakui as an example, the article lists in detail a parameter comparison between the conventional three-stage method and this simplified brewing method, making it easy for everyone to reproduce at home.
