What kind of water is best for brewing coffee?

We all know that about 98.5% of the dark, full-bodied, caffeinated drinks consumed in daily life are water, but it doesn't look like water, doesn't feel like water, and tastes even less like water, but water is the most important part of this drink. Although the main body of coffee is almost full of water, coffee should taste like coffee. If it tastes like chlorine, there is something wrong with the water quality. If it smells like sulfide, you are in big trouble!

Coffee water can be divided into soft water and hard water. After calculating the amount of sodium and manganese dissolved in water, the amount of soft water is less and the amount of hard water is more. General water is hard water containing sodium, manganese, calcium, magnesium, etc., because hard water will release caffeine and tannin, which greatly reduces the taste of coffee. Most mineral water belongs to hard water, so it is not suitable for making coffee. Ordinary tap water can be used as soft water, but the first tap water in the morning, the water taken the day before and the second boiled water should be avoided as far as possible. If you use water purifier and activated carbon filter, you can also avoid impurities and odors in the water. The ideal pH value of water is between 6.8 and 7.3. When brewing coffee with high pH water, it is easy to flush out the bitter or astringent taste, but not sour and dull flavor.

In fact, water quality is as important as coffee bean producing areas. Coffee lovers pursue a perfect cup of coffee, so people pursue perfection in the roaster, planting technology, brewing equipment and bean grinder. However, if it is cooked according to arbitrary water quality standards, it will undermine previous efforts to pursue perfection. We look forward to the development of different water purification facilities in different coffee producing areas in the future, and then there may be the argument that "the water quality suitable for brewing Mantenin coffee is not suitable for brewing Kenyan coffee." at that time, 98.5%, which is now ignored by most people, will get the attention it deserves.

Tips:

Freshly ground coffee powder, like activated carbon, has a filtering effect. That is, the effect of absorbing the stench of evil water. The average coffee lover doesn't have to be too rigid about water quality. As long as you use delicious and fresh coffee beans, you can enjoy delicious and mellow coffee.
