Question

Wine and beer are produced directly by fermentation. Brandy and whisky require both fermentation and distillation because
A. Fermentation is inhibited at an alcohol level of 10-18 percent
B. Distillation prolongs storage
C. Distillation improves quality
D. Distillation purifies the beverage

Answer 1

Hint:-The fermentation of yeast helps in the formation of alcoholic drinks such as wine and beer. The sugar source is converted into alcohol and carbon dioxide is also produced in this process. Beer is made from barley and wine is made from the fermentation of grapes.

Complete Answer:-
Beer is an alcoholic drink which is formed from lower alcoholic content and is formed by the fermentation of barley grains. The alcoholic content in wine is higher than that of beer and it is produced by the fermentation of fruit juices or grapes. Higher levels of concentration of alcohol in a beverage kills the bacteria which prevents spoilage as well as fermentation. Brandy and whisky are produced by the distillation of the fermented fruit juices. These liquors are produced by the process of distillation to extract the flavours produced by flavouring materials and then are extracted and diluted with water to make flavoured alcoholic beverages. If the beverage formed contains low alcoholic content, then it will lead to its spoilage. Distillation of brandy takes time as it is made from fermented wine. In the first phase, low wine is formed which is distilled in order to produce brandy. Whisky is distilled two to three times in order to enhance its taste.
The correct answer is Option A.

Note:- At higher alcohol concentration levels in a beverage, fermentation gets inhibited and the bacteria also gets killed. This prevents spoilage of the beverage due to over fermentation. To produce the best quality of alcoholic beverages, good raw materials and ample amount of time are needed for the proper fermentation of the raw material.
