The relationship between coffee and water what kind of water can be named coffee is more delicious?

There are all kinds of water around us. Some are also called water. There are also many kinds of mineral water in the world. However, the most convenient water is tap water that is available at the turn of a tap. So, what kind of water can be named coffee more delicious?

After mineral water is boiled, it seems that coffee is not good to drink. There must be many people who have had this experience.

Why?

In fact, that is because mineral water is hard water containing sodium, manganese, etc.

Water can be roughly divided into "soft water" and "hard water." Dissolve sodium or manganese in water. After conversion, the less acidic sodium is soft water and the more is hard water.

Generally so-called delicious water "name water" or "mineral water" mostly high hardness, in order to make it feel delicious, and coffee counterproductive. Hard water extracts and breaks down the bitter components of coffee that form the palatable caffeine or good quality caffeine.

Ordinary drinking water (tap water) can be thought of as soft water. In short, there is no need to prepare special water, and as long as you turn the tap, you can have very delicious coffee water. However, please note the following points:

① When the chlorine smell used for disinfection is too strong, it should be avoided to drink. Do not use unless it is colorless and odorless.

② When the taste is too strong, you can slowly heat it to boil, so that carcinogens can be removed.

Do not use water that has been boiled twice to make coffee. (The first tap water in the morning and the water taken and discharged the day before should be avoided as much as possible).

4. Boiling fresh water is the most appropriate.

Activated carbon filters and water purifiers are also good methods.

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