What is the purpose of mashing in the brewing process?

• A. To increase bitterness
• B. To carbonate the beer
• C. To convert starches into fermentable sugars
• D. To extract flavors from hops

Answer: (C)

Mashing is a critical step in the brewing process primarily aimed at converting starches present in the malt into fermentable sugars. During the mashing stage, crushed malted grains are mixed with hot water, which activates enzymes, particularly amylase. These enzymes break down the complex carbohydrates and starches into simpler sugars such as maltose and glucose, which are essential for fermentation. This conversion is essential because yeast, which is responsible for the fermentation process, primarily consumes these fermentable sugars to produce alcohol and carbon dioxide. The efficiency of mashing significantly impacts the overall yield of fermentable sugars and, consequently, the final alcoholic strength and flavor profile of the beer. In contrast, processes like increasing bitterness or extracting flavors from hops occur at different stages of brewing, such as during boiling or hopping, and are not related to the purpose of mashing. Carbonation also occurs after fermentation and is not a function of the mashing process itself. Thus, the correct understanding of mashing being about the conversion of starches into sugars is vital for comprehending the foundations of brewing.
