Understand the relationship between coffee and water. Make a good cup of coffee.

Making coffee after boiling mineral water does not seem to taste good, and there must be someone who has had this kind of experience.

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 sent to a faucet. So, what kind of water can be named coffee is more delicious?

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". Will melt in the water sodium or manganese, after conversion, the acid sodium content is less is the soft water is more is the hard water.

Generally speaking, the so-called "famous water" or "mineral water" has 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 differentiate.

The popular drink water (tap water) can be thought of as soft water. In short, there is no need to prepare special water, but you can have very delicious coffee water as long as you turn the tap. 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. It can not be used unless it is colorless and odorless.

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.

It is best to boil the water just taken by ④.

⑤ filter equipped with activated carbon and the use of water cleaner is also a good way.

When the meaning of ② is too strong, it can be slowly heated to make it boil, so as to remove carcinogens.

After such consideration, there is no need to be too rigid in water quality. As long as you use delicious and novel coffee beans, you can enjoy delicious and mellow coffee.
