Do you know the importance of water to coffee?

First of all, the water must be clean, odorless and pollution-free. In many cities with poor water quality, tap water contains more impurities and chlorine, resulting in a large smell of water, which will have a serious impact on the taste of coffee. There is also sediment in the pipe, which will also affect the texture of the water, so it is recommended that you had better use filtered water to make coffee.

Secondly, the "soft" and "hard" of water also have an influence.

For the bottled water on the market, you will hear that there are "soft" and "hard". So the so-called "soft" and "hard" refers to the total concentration of calcium and magnesium ions in the water, low concentration is soft water, high concentration is hard water. But soft water and hard water does not mean which kind of water is good for brewing coffee, but it depends on which kind of water brews coffee, which is more in line with your preference. Soft water taste clean and refreshing, brewed coffee taste smooth, easy to show the sour taste of coffee and its own characteristics; hard water will cause coffee bitter taste, taste irritation, roasted aroma will also be obvious.

For example, the well-known Evian, taken from the water source of Cachat in the small town of Yiyun near Lake Neiwa in the foothills of Mount Bailang, is a world-famous medium-hard water. The forest water in Japan is a bottled soft water made by absorbing the natural water nurtured by nature from various water sources in Japan and sealing bottles directly on the spot.

Finally, the water temperature is also the key point.

Coffee is different from tea, do not use freshly boiled water to make coffee! The water for brewing coffee should not be higher than 96 °, nor should it be too low. If the water is boiled a little, cool for 2 minutes before brewing coffee, and do not use warm water that has been kept for a long time, it is best to start with cold water and heat to the right temperature before making coffee. And brewing coffee with high-temperature water above 90 °will bring out a strong bitter taste, while a low water temperature will make the sour taste appear. In addition, the injection of hot water is slow, the bitter taste will be strong, on the contrary, it will be sour.

So water has a great influence on the taste of a cup of coffee, not which kind of water brewed coffee tastes best, but what kind of water brewed coffee taste is your favorite.
