Coffee taste is influenced not only by the coffee beans themselves, but also by the roasting and the extraction rate. As a normal customer, the most easy thing we can influence about a cup of coffee is the extraction. When it tastes bitter, less stir less duration lower water temperature and grinding rougher. While it tastes underdeveloped, do the opposite. Anbachi coffee concentration meter provides a solution to judge your coffee by modern technology instead of by your own tongue. According to the chart, the grams number to one litre water you brewing is probably between 47 to 70 g. For example, when you brewing 60g coffee beans with one litre water, and you test your coffee liquid got a reading 1.60%, you probably got a bitter cup. It also means you're over extraction, the ratio might be over 22% and you know how to fix this next time.
