Question

Choose the odd one out with respect to distilled alcoholic beverages.

• A. Brandy
• B. Whiskey
• C. Beer
• D. Rum

Answer 1

The correct option is C Beer

In the process of producing alcoholic beverages, different substrates such as grape juice, sugar cane, cereals, etc. are converted to alcohol and carbon dioxide anaerobically, by the action of the yeast Saccharomyces cerevisiae. This process is called alcoholic or ethanol fermentation.

In order to increase alcohol concentration, the liquid containing ethyl alcohol is heated to a high temperature and the vapours coming off the liquid are condensed. The condensate will have a higher alcohol concentration. This process is called distillation.

Depending on the type of the raw material used for fermentation of alcoholic beverages and the type of processing, with or without distillation, various types of alcoholic drinks are obtained. Wine and beer are produced without distillation
whereas whisky, brandy and rum are produced by distillation of the fermented broth.
