The relationship between coffee and water

There are all kinds of water around us. Some are called Mingshui. There are also rich types of mineral water in countries all over the world. However, the most convenient water is tap water that can be turned to a tap. So, what kind of water can be named coffee is more delicious?

Making coffee after boiling mineral water doesn't seem to taste good. There must be a lot of people who have had this kind of experience.

Why?

In fact, that is because mineral water is hard water containing sodium, manganese and so on.

Water can be divided into "soft water" and "hard water". Sodium or manganese will be dissolved in water. After conversion, the amount of acidic sodium is less than that of soft water and more is hard water.

Generally speaking, most of the so-called "famous water" or "mineral water" have high hardness in order to make it feel delicious, while coffee is counterproductive. Hard water will cause coffee to form delicious caffeine or good quality rather bitter ingredients to extract and decompose.

Ordinary drink water (tap water) can be thought of as soft water. In short, there is no need to prepare special water, but just turn the tap to have very delicious coffee water. However, please pay attention to the following points:

When the stench of chlorine used in ① disinfection is too strong, you should avoid drinking it. Must be colorless and odorless and cannot be used.

When the meaning of ② is too strong, it can be slowly heated to make it boil, thus removing carcinogens.

③ secondary boiling water should not be used to make coffee. Try to avoid the first tap water in the morning and the water taken the day before.

The water just taken by ④ is most suitable for boiling.

⑤ with activated carbon filter and the use of water purifier is also a good method.

However, the freshly ground coffee powder, like activated carbon, has a filtering effect. That is, the effect of absorbing the stench of evil water.
