Unraveling the Mystery: Water Hardness in Brewing Water for the Perfect Beer

Welcome to the exciting world of water hardness in brewing water! This crucial factor can make or break your favorite beverage, so let’s dive into what it’s all about.


Besides water hardness, other essential values in brewing water include pH, alkalinity, and mineral content. Each of these components plays a vital role in determining the overall taste and quality of the final product.

How would super hard water taste like?

Super hard water would have a strong mineral taste, primarily due to high concentrations of calcium and magnesium. This could result in an unpleasant or overpowering flavor, masking the subtler notes in your beverage.

Influence on beer taste

Water hardness affects beer taste in several ways. For instance, high levels of calcium can enhance yeast fermentation, while magnesium can contribute to a bitter aftertaste. On the other hand, soft water can create a more delicate and balanced flavor profile. Hence, the water hardness level can significantly impact the final taste of your beer.

A few examples of water hardness levels in brewing water

Brewing water with high water hardness levels often comes from sources rich in limestone or gypsum, such as well water or some tap water. Some examples of brewing water and their water hardness levels include:

  1. Pilsen, Czech Republic: Known for its soft water with low levels of water hardness, perfect for brewing Pilsner-style beers.
  2. Burton-on-Trent, England: Renowned for its hard water, contributing to the unique flavor profile of English pale ales.


In conclusion, water hardness plays a critical role in the brewing process, affecting everything from fermentation to the final taste of your beer.
