Grind size is the key variable that determines the direction of coffee flavor, but how coarse counts as coarse and how fine counts as fine has always lacked a unified standard. This article uses the industry-recognized cupping grind as a baseline, and with the help of the passing rate through a No. 20 standard sieve, quantifies the grind requirements for French press, pour-over, cold brew, ice drip, and even espresso machines one by one, and also includes reference settings for the EK43s grinder. The article also specifically reminds readers that differences in coffee bean density and roast level will cause the same setting to produce different particle sizes, and finally provides Front Street Coffee's espresso extraction plan as a debugging example to help enthusiasts turn grinding from an empirical judgment into a reproducible data-driven operation.

The Hoop dripper from the Italian brand Ceado won the 2023 SCA Best Product of the Year award thanks to its unique ring-shaped water dispensing structure. It completely separates the water dispensing zone from the coffee bed, with water seeping laterally from the outer water crown through 12 small holes into the filtration tower, creating a slow, immersion-like extraction. This design eliminates the need for consistent pouring technique, but places more refined demands on grind size and water temperature. Front Street tested three coffees—Sidra, Yirgacheffe Kochere, and Golden Mandheling—to compare the flavor differences between the Hoop and the V60, and compiled six practical tips, including checking the filter paper seal,适配 of the server, and the consideration of a purchase cost as high as 280 yuan.

Should ice be added before or after brewing when making iced pour-over coffee? This question puzzles many coffee lovers. Front Street Coffee conducted a controlled experiment using 15 grams of Kaffa Forest coffee beans, a 1:10 coffee-to-water ratio, a water temperature of 90-91°C, and a grind setting of 9 on an EK43s grinder, testing two brewing sequences: ice added first and ice added last. The experiment found that after thorough shaking, the two methods performed quite similarly overall, but the coffee with ice added first tasted cleaner and more refreshing, while the one with ice added last had a more concentrated and intense aroma. The root of the difference lies in how much ice melts. This article will present the complete experimental parameters, step-by-step procedure, and sensory comparison results to help readers understand how the timing of ice addition affects the flavor of iced pour-over coffee.

When the weather turns hot, iced coffee becomes the first choice for many people. Iced pour-over preserves the flavor layers of pour-over coffee while adding a refreshing chill, but making a good iced pour-over isn't as simple as adding ice cubes to hot pour-over. Melting ice dilutes the coffee's strength, and directly applying hot-brew parameters often results in a weak glass of iced coffee water. This article centers on the two cores of extraction yield and strength, and compiles four zero-threshold iced pour-over methods: the high-strength high-extraction method, the ice-rinsing method, the stirring method, and the ice-bath cooling method. Each method comes with specific parameters and operating steps using a medium-light roast Front Street Coffee Kafa Forest as an example, helping you easily make a full-flavored, sweet-and-sour balanced iced pour-over at home.

As soon as the temperature rises, iced coffee returns to the top of the sales charts. Iced pour-over lets you choose your own beans and comes with a refreshingly cold taste, making it the first choice in hot weather. However, if you simply add ice cubes to a hot pour-over recipe, the concentration gets diluted and it tastes as bland as water. The core problem to solve is: how to maintain a moderate concentration after cooling down. Using Front Street's medium-light roasted Ethiopia Kaffa Forest as an example, we've put together four highly practical iced pour-over methods—high-concentration high-extraction, ice-flushing, stirring, and ice-bath cooling—breaking down the parameters and techniques one by one, and comparing their flavor performances, to help you find the cup that suits you best.
