Water makes up the largest percentage of a finished beer. The type of water and mineral content of the water can significantly alter the flavor and aroma of the finished beer. Water plays a significant role in most of the brewing processes including mashing, hop utilization during boiling and yeast performance during fermentation.
Characterizing Water
Brewing water is usually categorized using a profile of Calcium (Ca), Sulphate (SO4), Sodium (Na), Chloride (Cl), Carbonate (CO3) and Magnesium (Mg) ions. In addition the overall alkalinity becomes important when adjusting pH for mashing all-grain brews. Calcium and Carbonate play a significant role in mash alkalinity, as carbonates buffer the alkalinity of the mash, raising pH.
Water and Beer Styles
The most famous styles for a given city are typically closely tied to the water available. For example, the famous Pilsner style originated in the city of Pilsen, Czech Republic. Their soft water has very low levels of all minerals, which aids in producing a pale color lager with clean bitterness. Similarly the high levels of calcium, carbonate and sulfate of Burton on Trent's hard water in the UK help produce unique hoppy English pale ales. For examples of some brewing waters from around the world, see the hops table in the external links below.
Adjusting Water
You can add minerals to your water to adjust the alkalinity for mashing and also to add minerals for flavor complexity. The most popular additives are Gypsum (CaSO4), Chalk (CaCO3), Calcium Chloride (CaCl), Salt (NaCl), Baking Soda (NaHCO3) and Epsom salts (MgSO4). Carbonates can be used to reduce or buffer the alkalinity of the mash. Brewing software or a water calculation tool can help you determine the correct amount of additives to use.
