Alkalinity

Parameter Selection

Application Importance of Alkalinity in Brewing

An essential parameter to measure in brewing water is total alkalinity. This is a measurement of the carbonate (CO3), bicarbonate (HCO3-), and hydroxyl (OH-) ions present in the water and influences the mash’s ability to resist pH changes. While the recommended level of alkalinity varies a bit based on style, it is recommended to keep alkalinity at a value less than 100 ppm. For lighter beers will have a lower alkalinity, while darker beers will have a higher alkalinity.
