How to choose water for coffee

In this article, we will tell you why ordinary tap water, which is suitable for all needs, is completely unsuitable for making coffee and how you can fix it.
To understand why this is happening, we turn to the official requirements for water, where there are certain standards for its quality.

Drinking water is safe by general standards, but not suitable for making coffee
Official standards determine the quality of tap water, regulating its chemical composition and its compliance with the required properties in terms of color, smell and taste. According to these standards, there can be no toxic elements dangerous to life or any other substances in the water. These requirements are necessary so that you and I can safely use water for our daily needs for our lives.

Safe water is our health!

Drinking water is suitable for almost everything, but for the safety of our health, various minerals are added to it. And at certain times of the year, like in autumn and spring, the amount of precipitation increases significantly and more special substances, such as chlorine, are added to water. Such water is certainly safe for health, but not suitable for making coffee.

Why is tap water not suitable for coffee?

As we have already written above, ordinary water is not suitable for making coffee, since its composition is heterogeneous, although it is safe for use in household needs, it is not suitable for coffee. Ideal for coffee would be a combination of all requirements with general standards for water quality with no color, odor and impurities of other substances. According to a special standard, chlorine should not be present in the water, since its presence in the water adds extra bitterness to coffee. Another important factor affecting on water quality is the general level of water salinity. Tap water is oversaturated with various minerals and has some low values, which makes coffee with such water tasteless.

And for coffee to be tasty and aromatic, you need ideal water parameters without being oversaturated with calcium, which again will make the drink watery. Unpleasant and dull coffee can be due to the increased acidity, which is regulated by the carbonate liquid. And just in tap water, this indicator (pH – the balance of alkali and acidity) is often higher than normal.

And when the pH is below normal, the water becomes too acidic and the coffee made with such water will be too bitter, and vice versa, if more alkali in the water, the coffee turns out to be empty and tasteless. Also, bitterness can be caused by an increased content of sodium salts in tap water. The correct coffee can only be obtained by brewing with neutral water.

 

Ways to make tap water suitable for making coffee

Large amounts of minerals in tap water with various substances can be removed by settling and boiling. But the complexity of this process lies in the impossibility of controlling it, and if by settling tap water during the day it is possible to completely remove all chlorine from it, then heat treatment of water will not be able to completely remove unnecessary elements from the water. This water will not be suitable for coffee.

Suitable water for coffee

To get a good result in the form of delicious coffee, you need water that is not too soft and at the same time not quite hard. At the same time, tap water must comply with all generally accepted standards and indicators.

There are several ways to solve this problem: choose special bottled water, install a specific water treatment system, or use household filters with special modules that will make the water meet the required parameters. Bottled water will be enough to make coffee at home, and filters can be used if you want more coffee.
