Adjust the degree of grinding (that is, the contact area between coffee and water); 2. Adjust the brewing time (that is, the contact time between coffee and water); 3. Adjust the temperature and concentration of water: the weight of coffee ingredients as a percentage of the total liquid weight of coffee. For example, in a cup of 200 grams of coffee, the concentration of coffee may be only 1.

1. Adjust the degree of grinding (that is, the contact area between coffee and water)

two。 Adjust the brewing time (that is, the contact time between coffee and water)

3. Adjust the temperature of the water

Concentration: the weight of coffee ingredients as a percentage of the total liquid weight of coffee.

For example, in a cup of 200 grams of coffee, the concentration of coffee may be only 1.2-1.5%, that is, the weight of coffee in this cup is only 2.4-3 grams, while the rest of 197.6 grams of 197.6 grams of coffee is water.

Case 1: this cup of coffee is extracted too little. (the extraction rate is less than 18%)

Case 2: the extraction rate of this cup of coffee is normal (18-22%), but the concentration is too low. In this case, the coffee may not have obvious characteristics, but it will not have a bad taste and flavor.

Case 3: this cup of coffee is overextracted (more than 22%), but the concentration is too high. In this case, the coffee will still show the characteristics of over-extraction, can drink a faint bitter taste or unpleasant miscellaneous taste. The relationship between concentration and taste:

Appropriate coffee concentration (black coffee, refers to brewed coffee): 1.15-1.35 (SCAA standard); 1.2-1.45 (SCAE) standard.

The concentration is too high (when the concentration of black coffee is more than 1.5%): the coffee tastes too strong, especially the sour and bitter taste, and the sweetness is not enough; the flavor of good coffee is not obvious and is easy to be misunderstood as' over-extraction'.

The concentration is too low (when the concentration of black coffee is less than 1.15%): the taste of coffee is too light, the sour, sweet and bitter taste are not obvious, and the flavor characteristics of coffee are not obvious, so it is easy to be misunderstood as' too little extraction / insufficient extraction'.

How to adjust the concentration?

Adjust the ratio of powder to water (when other conditions are constant, if there is more powder and less water, the concentration will be high; if there is less powder, the concentration will be low.)
