Answer
Fermentation is used in the process of making beer and wine because the yeast converts sugar into alcohol and carbon dioxide, which give the beverages their alcoholic strength and their effervescence. Additionally, fermentation contributes to amplify the flavors and aroma, giving each beverage a unique and detailed taste.
Explanation
## Step 1: Understand and Identify Key InformationIn the given question, we need to explain why fermentation is necessary in the production of beer and wine. We know fermentation is a biological process in which sugar is converted into alcohol and carbon dioxide in the absence of oxygen, and it is essential in making alcoholic drinks like beer and wine. ## Step2: Define the Role of Fermentation in Alcohol ProductionDuring the fermentation process, the yeast metabolizes the sugar to alcohol and carbon dioxide using its enzymes. This conversion gives the alcohol its distinguishing characteristic. The carbon dioxide forms bubbles that cause the beer to foam or produces the fizz in wine or bubbly.## Step3: Explain How Fermentation Amplifies TasteFermentation doesn't only produce alcohol and carbon dioxide, it also creates other compounds like esters, phenols and other molecules which contribute to the flavor and aroma of the beer or wine. By altering the types of yeast, fermentation times and temperature, the kind and amount of these flavorful molecules can be manipulated to produce a wide spectrum of tastes and tones making beer and wine unique and varied.
