Basic knowledge of coffee what kind of water should be used to make coffee

Just as water is essential for brewing tea, water is essential for extracting coffee.

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

natural water

These include spring water, river water, well water, lake water and rainwater, which are generally not suitable for extracting coffee.

artificially treated 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 flushing pots, etc., generally choose purified water or distilled water, and use coffee machine to make ESPRESSO, then generally use softened water, do not use distilled water and ultra-pure water, water quality is too clean pure water will cause coffee machine can not detect the water level in the boiler through the water level probe.

In addition, we should also note that it is best not to use boiled water for making coffee with handmade utensils, because the water will expel the air in the water during the boiling process, and the coffee extracted with such irritating water will make the coffee lose its freshness.
