Application Importance of Chlorine in Brewing

Chlorine is an effective disinfectant that works by oxidizing the cellular membranes of microorganisms. As a result, chlorine is added to municipal water sources as a way to remove any organisms that could adversely affect your health. While chlorine is good for drinking water, it is not good for brewing as chlorine can cause off flavors and byproducts in beer. Additionally, chlorine can have a negative effect on reverse osmosis membranes used for filtration due to oxidation. A brewer should test the chlorine levels of their source water, aiming for a goal of zero ppm. A carbon filter can be installed to help remove any residual chlorine.

It should be noted that chlorine can be measured as free or total chlorine. Free chlorine refers only to unbound chlorine whereas total chlorine is the measurement of both bound and unbound forms. If chloramines are used in a water supply, often seen in municipal water sources, then a ‘total chlorine’ test is required.
