The quality of the water is essential to prepare a good coffee. Contaminated, altered, or foul-smelling water negatively influences the final flavor of the cup. Keep in mind that when we brew coffee, we put 90% water, and if this proportion is not balanced according to the parameters or in good condition, the coffee will have an unpleasant taste.
Natural water integrates a series of minerals such as calcium, chlorine, fluorine, and iron, elements that are present as chemicals and sediments of water.
If any of these elements exceed the normal amounts will cause changes in the flavor of the coffee. Poor water quality can cause the following problems:
- Bad smells.
- Increase in acidity.
- Little body.
- Inconsistent cream.
- Presence of solid microparticles.
- Presence of organic matter.
Always pay attention to the quality of the water!
Many variables must be considered to determine the water quality and assess whether or not it is suitable to make a good coffee.
One of the methods to assess water quality is to measure total dissolved solids (TDS). Dissolved solids consist of minerals such as magnesium, sodium, potassium, carbonate, bicarbonate, chlorine, sulfate, and nitrates in groundwater.
Hardness refers to mineral concentration in water, such as calcium, magnesium, iron, and manganese. The greater the presence of these minerals, the greater the hardness of the water.
Potential for hydrogen (PH)
PH is an indicator of the acidity and alkalinity index of water. It also measures the concentration of hydrogen ions (H+).
The standards required to make a coffee with quality water are as follows:
- TDS is between 75 and 200 milligrams.
- Hardness between 17 and 85 milligrams.
- PH of 7.0.
- Total alkalinity of 40 milligrams.
- Sodium between 5 and 10 milligrams.
- Calcium is not greater than 30 milligrams.
- Without the presence of chlorine.
Both grains and water must meet generally accepted quality standards to prepare a good coffee. These are decisive aspects for the final cup of coffee to have good taste. Follow us on social media for more information about preparing quality coffees.
