In discussions about pour-over coffee, the 1:16 coffee-to-water ratio is often dubbed the "golden ratio," so some friends are surprised that Front Street Coffee uses 1:15 in its daily routine. Behind this lies the Golden Cup extraction theory—Dr. Lockhart's research indicates that most people prefer coffee with a concentration between 1.15% and 1.35%, and an extraction yield between 18% and 22%. The Golden Cup extraction chart visually illustrates the relationship between coffee-to-water ratio, concentration, and extraction yield, and 1:16 happens to be a ratio that easily falls within the ideal range. However, the Golden Cup standard is only a reference, not an absolute rule: tastes vary from person to person—1:14 or even 1:10 suits those who prefer a strong brew, while 1:17 to 1:20 is better for those who enjoy a lighter taste. Front Street Coffee chooses 1:15 to make the flavors more concentrated and the mouthfeel more substantial, and it adjusts the water temperature and grind based on the roast level. This article will provide a complete analysis of the origin of the golden coffee-to-water ratio, the true meaning of Golden Cup extraction, and Front Street Coffee's specific brewing parameters for beans such as Huakui, Geisha, Queen's Estate, and Golden Mandheling.

Brewing a good cup of coffee, the coffee-to-water ratio and extraction yield are core parameters that cannot be avoided. The SCA Golden Cup extraction theory gives an ideal range of 18%-22% extraction yield and 1.2%-1.45% concentration, but many enthusiasts easily misunderstand it as "as long as you copy the Golden Cup coffee-to-water ratio, you will definitely brew a good cup of coffee." This article starts with a simple calculation of the coffee-to-water ratio, guides you to understand the meaning of the Golden Cup extraction range, clarifies the boundary between over-extraction and under-extraction, and explains the true value of learning the Golden Cup theory—not rigidly sticking to a certain ratio, but using it to adjust brewing variables and more flexibly approach the flavor you want. Front Street Coffee also shares related products and brewing ideas in the article for coffee enthusiasts' reference. [more…]
