What is the definition of one person? If it is calculated according to the volume of coffee liquid, then first assume that you drink a cup of 300ml of coffee at a time.
You must know that coffee beans are insoluble in water, and at most 30% of the ingredients in it can be extracted by water, but we cannot extract all the substances in the coffee beans, because the substances extracted later are more bitter and stronger, then the coffee will not taste good. Therefore, it is generally recommended that the extraction rate of coffee be about 18% or 20%, and the coffee will be delicious. The recommended basic ratio of coffee powder and water is 1:15 (of course, the ratio can also be adjusted according to your own preferences). So if you drink a cup of 300ml coffee, you need to use about 20 grams of coffee beans.
