Citric acid is often utilized in brewing to achieve a crisp and tangy flavor profile, particularly in styles like sour beers, fruit-flavored beers, or light and refreshing brews like certain wheat beers. It can be added during various stages of the brewing process, including during the boil, fermentation, or even directly to the finished beer.
Additionally, citric acid can also be employed as a cleaning agent in the brewing equipment and as a sanitizer due to its antimicrobial properties.
In summary, citric acid is used in brewing primarily to adjust acidity levels, enhance flavors, and contribute to the overall character of the beer, particularly in styles where a bright and tangy profile is desired.
