City (Municipal) Water


Water Impact: Treated with Chloramine

City (Municipal) Water Home Brewing Uses

City water is a term used for any water delivered to your home by your local municipality. The local water agency typically takes water from an outside reservoir and treats it with chloramine. Chloramines are disinfectants used to treat drinking water to ensure it is and stays safe. City water should be de-chlorinated with sodium metabisulfite (Campden tablet) before being used in home brewing.

Almost every city’s tap water, regardless of where you are, is generally going to be higher in alkalinity and lower in hardness than we would prefer to have for brewing beer.

In home brewing, it is safe to be used hot side during the boil as-is, but should not be used to "top off" any partial boils unless the water has been pre-boiled to sanitize it beforehand.
