Factors affecting the taste change of coffee during coffee making

1. Water quality: like making tea, coffee must pay attention to water quality. Water containing large amounts of iron and alkaline hard water should not be used. The most ideal water should be distilled water. In addition, there are certain requirements for water temperature, the water temperature should be between 80 ℃-90 ℃, do not use boiling water, otherwise it will increase the bitterness of coffee and reduce the quality of coffee.

2. Soaking time

As coffee contains caffeine and aromatic oil, soaking time should not be too long, usually soaking for about 2 minutes, too long soaking not only destroys the flavor of coffee, but also causes floating matter on the coffee liquid and makes the coffee turbid.

3. utensils

It is most appropriate to use glassware and ceramic utensils to make coffee. If metal utensils are used, it will oxidize, giving the coffee an unpleasant taste.

4. Dosage

The amount of coffee should be determined according to the size of the coffee particles and the preference of the coffee drinker. Usually fine powdered coffee is less than fine granular coffee, while coarse granular coffee is about 15% more than fine granular coffee. If you brew 40-50 cups of coffee with 500 grams of coffee, it is espresso.
