Which factor is affected by pH during the brewing process?

• A. Fermentation vessel type
• B. Enzyme activity
• C. Yeast strain selection
• D. Bottling technique

Answer: (B)

pH plays a crucial role in enzyme activity throughout the brewing process. Enzymes are sensitive to pH levels, and their effectiveness can vary significantly depending on the acidity or alkalinity of the brewing environment. For instance, during the mashing phase, the optimal pH range for amylase enzymes, which break down starches into sugars, is typically around 5.2 to 5.6. If the pH falls outside of this range, the activity of these enzymes can be hindered, leading to inefficient sugar extraction and ultimately affecting fermentation and beer quality. Moreover, other enzymes, like proteases, also exhibit specific pH optima, making it essential to monitor and adjust the pH during mashing. This impacts not only the conversion of starches but also the clarity and stability of the finished beer. Thus, understanding how pH influences enzyme activity is fundamental for brewers aiming to produce high-quality beer.
