What is the primary purpose of primary fermentation?

• A. To clarify the beer before bottling
• B. To convert sugars into alcohol and carbon dioxide
• C. To add hops for bitterness
• D. To cool the wort before pitching yeast

Answer: (B)

The primary purpose of primary fermentation is to convert sugars into alcohol and carbon dioxide. During this phase, yeast is added to the wort, which is the liquid extracted from the malted grains and contains fermentable sugars. The yeast metabolizes these sugars and produces alcohol as a byproduct, which is essential for the creation of beer. Additionally, carbon dioxide is released during this process, contributing to the beer's carbonation. This step is fundamental to brewing because it not only provides the alcoholic content of the final product but also influences the flavor profile, aromas, and overall character of the beer. It is during primary fermentation that yeast plays its crucial role, transforming the sweet wort into a complex beverage. The other options relate to various processes in brewing but do not represent the primary function of fermentation itself. Clarification typically occurs later in the brewing process, hop additions are made for flavor and bitterness rather than during fermentation, and cooling the wort is a pre-fermentation step to ensure the yeast is pitched at the appropriate temperature.
