What kind of water should be used to extract coffee?

1. Freshness means that the water is rich in oxygen and vitality. And to start with cold water, it is best not to use cold water directly.

2. Tasteless, many cities with poor water quality have high levels of phosphorus and chlorine in their tap water, which leads to a strong flavor and a heavy impact on the taste of coffee.

3. The acidity is very easy to understand. The best bubble water is neutral water with a pH value of 7, which is not acidic or biased.

4. Pollution is also important. However, it is necessary to pay attention to the fact that it is too much. The extracted coffee liquid tastes strong, thin and rigid, and the sense of richness and taste is poor. Some people use a mixture of tap water and tap water at the ratio of 10:1, and the effect is very bad.

In addition, there has always been a debate about whether to use partial or hard water to extract coffee. Individuals think that it is not good to use water that is too hard or too weak to make coffee. the water is preferably "hard" and has a low mineral content.
