從萃取率簡單的看滋味
影響一杯咖啡好壞的因素眾多，可以從萃取率簡單的看滋味，萃取率高於22%易有苦澀感和咬喉感；萃取率低於18%易有呆板的死酸感。
There are many factors that affect the taste of a cup of coffee, and extraction rate is a simple way to gauge its quality. An extraction rate higher than 22% may result in bitterness and astringency, while a rate lower than 18% may lead to a flat and sour taste.
