What kind of water should be used to make coffee? What kind of water is the best for making coffee?

Just as water is important for making tea, it is also essential for extracting coffee. To extract coffee, we need fresh, odorless, moderate pH and pollution-free water.

1. Fresh means that the water is rich in oxygen and full of vitality. It is also recommended to start with cold water, and it is best not to use warm water directly.

2. There is no peculiar smell, and there are many impurities and high chlorine content in tap water in many cities with poor water quality, which leads to strong smell and serious influence on the taste of coffee. Baristas and coffee lovers are advised to spend more time on water treatment.

3. The moderate pH is very easy to understand. The best brewing water is neutral water with a pH value of 7, which is neither acidic nor alkaline.

4. No pollution is also extremely important, in other words, the water quality should be pure. But we need to pay attention to "go too far", too pure, the extracted coffee liquid taste strong, thin and rigid, rich and hierarchical sense is not good. Some of you mix pure water with tap water (no odor and no pollution) at 10:1, and the effect is said to be very good.

In addition, the use of soft or hard water for extracting coffee has always been controversial. Personally, I think it is not good to use too hard or too soft water to make coffee, the water had better be soft and hard, and had better contain low mineral substance.

It should be noted that if you use a coffee machine to make coffee, in order to avoid the accumulation of deposits in the hard water of 300mg/L and clog the pipes, it is necessary to carry out softening treatment (you need to buy water purification and softening devices), especially for friends who are engaged in running Espresso coffee machines.
