The reasons for the taste and taste of coffee

Coffee in a coffee cup

99% of the ingredients are "water".

From this point of view

Water can be said to be the key to the taste of coffee.

Does coffee made with mineral water taste better?

Ph value

Coffee brewed with mineral water tastes different from coffee brewed with ordinary water. The color of coffee brewed from mineral water is relatively dark, which is affected by the ph value in the water.

The ph value is used to indicate the acidity and basicity of the aqueous solution. When the water is at 25 degrees Celsius, the ph is exactly 7, and the water is neutral. If the value is greater than 7, it is alkaline and can neutralize with the acid. The ph of ordinary water is basically 7, while the ph of mineral water will exceed 8, which is alkaline water.

Coffee is a weakly acidic drink with a ph value of 5-6. If you brew coffee with weakly alkaline mineral water with a ph value greater than 8, it will neutralize part of the coffee and weaken the sour taste of the coffee. The higher the ph value, the stronger the ability to neutralize acid. Mineral water labels are usually marked with a ph value, which you can refer to when making coffee. For ordinary people, brewing coffee with mineral water may make people feel "blurred" in taste.

Many coffee experts believe that coffee is just like tea, it can be brewed with ordinary water. If you want to control the sour taste, instead of spending money on water, it is better to change the variety of roasted beans or the extraction time of coffee.

Which should you choose, soft water or hard water?

Soft water and hard water

The so-called hardness of water refers to the total concentration of calcium and magnesium ions in water, the lower concentration is soft water, on the contrary, the higher concentration is called hard water.

The taste varies according to the hardness of the water.

Instead of thinking about "what kind of water is best for coffee", use "what kind of water is the best for brewing coffee?" To make a choice.

People who like the smooth taste and sour taste of coffee can use soft water to brew coffee, and the aroma of beans will be more obvious when brewing. People who like the bitter taste of coffee usually prefer to use hard water to brew, and the aroma of beans is weak when brewing. In addition, between hard water and soft water, there are other kinds of water quality, including medium-hard water and very hard water.

Most of the tap water in our country belongs to hard water, and the water in the north is harder than that in the south.

Whether to use soft water or hard water for brewing coffee should be chosen according to personal "preference".

Summary

The ph value and hardness of the water will affect the taste and taste of the coffee. According to the rules mentioned above, combined with your preferred coffee taste, keep trying, I believe you will soon find the most suitable coffee water.
