Application Importance of pH in Brewing

In order to maintain a consistent flavor profile and ensure a stable product, pH should be monitored throughout the beer making process due to the effect it has on enzymatic activity, yeast fermentation and the incorporation of flavoring components.

During the mash, pH plays a vital role in the efficiency of starch breakdown. While each enzyme group operates at different temperatures and pH ranges, generally the breakdown of starch into fermentable sugars is optimal between pH 5.2 and 5.6.

Hop utilization is also dependant on pH. As the pH becomes more acidic, the solubility of the hop resin increases, releasing compounds that result in a more bitter tasting product. Brewers can add compounds such as phosphoric acid, lactic acid and salts, such as gypsum, to adjust the pH as needed.

During fermentation, the pH should be lower to accommodate the yeast and also to ensure microbial stability and consistent flavoring of the beer. For the best results, an optimal pH range during fermentation is between pH 4.1 and 4.3. In the end, fresh beer has a pH of about 4, dropping as oxidation occurs.
