粉水比 Coffee-to-Water Ratio

是指咖啡粉與沖泡使用水的比例。常聽到的手沖 粉水比 是1:15,即用20克的咖啡粉與300克的熱水。然而定義上卻有二種說法,其一是坊間常用的說法,用20克的粉、得到300克的咖啡液。

The coffee-to-water ratio refers to the ratio of coffee grounds to the amount of water used for brewing. The commonly heard coffee-to-water ratio for pour-over brewing is 1:15, which means using 20g of coffee grounds with 300g of hot water. However, there are two definitions for this ratio. The first definition is the commonly used one in which 20g of coffee grounds to get 300g of brewed coffee liquid.

 

其二是金杯理論的說法,用20克的粉、總給水量300克。因為咖啡粉會吸水,會有約1.5倍的水被咖啡粉吸附住不會流下來,所以第二種所得的咖啡液只有約270克。二種說法都是一個比值,這個比值讓我們每次沖泡咖啡有一個比較基準與參考。

The second definition is based on the "Golden Cup" standard, where 20g of coffee grounds are used with 300g water. Since coffee grounds absorb water, approximately 1.5 times the water weight is retained by the coffee grounds and doesn't flow through, resulting in a brewed coffee liquid of around 270g. Both definitions represent a ratio that provides a benchmark and reference for brewing coffee.
