What water should be used to make coffee? basic knowledge of coffee

Just as water is important for making tea, it is also essential for extracting coffee.

There are many kinds of water, which can be divided into:

Natural water

Including springs, rivers, wells, lakes and Rain Water, this kind of water is generally not suitable for extracting coffee.

Artificial treatment of water

Including tap water, distilled water, purified water, ultra-pure water, softened water, etc., in which we make handmade utensils, such as siphon pots, hand pots, etc., generally choose purified water or distilled water, while when using the coffee mechanism for ESPRESSO, we generally use softened water, do not use distilled water and ultra-pure water, the water quality is too clean pure water will cause the coffee machine through the water level probe to detect the water level in the boiler.

In addition, we should also note that the water for making coffee with handmade utensils had better not use boiled water, because the water will expel the air from the water during the boiling process, and the coffee extracted with that kind of irritating water will make the coffee lose its due freshness.
