Additionally, sulfate influences the perception of hop bitterness and can lend a dry, crisp finish to the beer.

Burton's unique mineral profile has historically played a pivotal role in its identity as a brewing center, famously associated with styles like Burton ales and the broader category of pale ales. Understanding the specific mineral content of brewing water is crucial, as it directly affects the flavor and mouthfeel of the beer produced.
