What kind of water is usually used for brewing coffee?

Coffee is the essence extracted from the meeting of coffee powder and water. Therefore, in addition to good coffee beans, water quality and water temperature are of course the key role in releasing the aroma of coffee. It is recommended that you install a filter containing activated carbon under the faucet so that you can have good water suitable for brewing coffee.

Which is the most suitable for hard water and soft water?

If you want to make a good cup of coffee, you need to work hard not just to choose and bake and brew it. 99% of the coffee poured into the cup is "water". From this point of view, water can be said to be the secret key to the taste of coffee.

When it comes to the nature of water, there are all kinds of bottled water on the market in recent years, and we can often hear words such as "hard water" and "soft water" in our daily life. In fact, according to the hardness of water, water is roughly divided into hard water and soft water. The hardness of the so-called hard water refers to the total concentration of calcium and magnesium ions in the water. The lower concentration is soft water, while the higher concentration is called hard water. For example, the tap water or groundwater in Japan is almost all soft water, while in Europe and the United States, it is mostly hard water. As for which kind of hard water and soft water is more suitable for brewing coffee, there is no definite answer, but the mineral content in the water does affect the taste of the water.

Generally speaking, water with too much or too little minerals is considered to be unbalanced water quality. It is assumed that the high content of calcium and magnesium ions will hinder the extraction of coffee main ingredients such as caffeine and high-quality tannin. On the other hand, if the water quality with high hardness is high, its effect will be directly reflected in the bitterness of coffee.

But then again, what kind of water can play the greatest sense of balance when brewing coffee depends on the individual's "taste" and "preferences".

Do you know,

There are certain conditions for good water!

In fact, there are four basic conditions for good water, namely, tasteless, colorless, containing the right amount of minerals (30-200mg/kg) and oxygen, and a water temperature of 10 Mel 15 ℃. It is precisely because of this that natural springs or groundwater that can meet these four conditions will brew delicious coffee.

Standard

Take your preferences as the benchmark. Coffee beans have a moderate personality, bitter, sour and strong taste balance, is the most standard taste. The speed of hot water injection extraction is also the standard speed.
