When brewing pour-over coffee, Front Street Coffee insists on using a 1:15 coffee-to-water ratio—why is that? Was this result arrived at by chance, or was it derived from various brewing experiments based on data? In this article, Front Street will explain why. [more…]

The coffee-to-water ratio is the first parameter to nail down in pour-over coffee, as it directly influences both the strength and the extraction yield. The American Coffee Association once arrived at a golden ratio of 1:18 through extensive research, but today's bean varieties and processing methods are vastly different, making this figure better suited as a starting point than an ironclad rule. Front Street Coffee's shops typically brew with 15 grams of grounds to a 1:15 ratio, meaning 225 milliliters of hot water is poured; when they want to highlight floral notes and acidity, they loosen the ratio to 1:16. This article explores how the coffee-to-water ratio affects flavor, how to fine-tune it for different beans, and a hands-on three-pour routine using 15 grams of grounds, helping beginners find a brewing rhythm that suits them.

Among the many variables in pour-over coffee, the coffee-to-water ratio is always the key parameter determining the direction of flavor. Front Street Coffee usually recommends a safe range of 1:15 to 1:16, and once you get used to it, 15 grams of coffee with 225 milliliters of water becomes almost the default operation. But in reality, we are not necessarily that precise every time, and the amount of coffee may be one gram more or one gram less. If the amount of water poured remains unchanged and only the coffee dose deviates by 1 gram, will the taste of the coffee show a noticeable difference? Through three controlled brewing experiments with 14 grams, 15 grams, and 16 grams, this article analyzes the impact of slight coffee dose adjustments on extraction yield and concentration, and provides parameter adjustment suggestions after the coffee dose changes, helping you achieve consistent results in daily brewing.
