Why Water Quality Matters in Coffee
Water is a crucial component of coffee, making up around 98% of the beverage. The quality of the water you use can greatly impact the flavor, aroma, and overall quality of your coffee. Here are a few reasons why water quality matters:
The Impact of Minerals on Coffee Taste
Tap water contains a variety of minerals, including calcium, magnesium, and potassium. While these minerals are essential for human health, they can also affect the taste of your coffee. For example, high levels of calcium can give your coffee a bitter taste, while magnesium can contribute to a sour or metallic flavor.
The Role of pH Levels in Coffee Extraction
The pH level of your water can also impact the extraction of your coffee. Coffee beans have a natural pH level of around 5.5, and using water that’s too alkaline or acidic can disrupt the extraction process. This can result in a cup of coffee that’s either under- or over-extracted, leading to a subpar flavor.
The Effects of Chlorine and Other Chemicals on Coffee Taste
Tap water often contains chlorine and other chemicals, which can give your coffee an unpleasant taste and aroma. Chlorine, in particular, can react with the coffee’s natural oils, resulting in a bitter or medicinal flavor.
