Which of the following statements about fermented beverages is correct?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Both (1) and (2)
Brewer’s yeast, Saccharomyces cerevisiae, ferments malted cereals and fruit juices to make ethanol. Different drinks are then obtained by processing the fermented broth with or without distillation.
Option (1) Brewer’s yeast ferments malted cereals and fruit juices to produce ethanol. — Correct statement, but it is only one of the correct points, so on its own it is not the answer. Brewer’s yeast ferments malted cereals and fruit juices to produce ethanol, which is the alcohol of all these drinks.
Option (2) Wine and beer are produced without distillation of the fermented broth. — Correct statement, but it is only one of the correct points, so on its own it is not the answer. Wine and beer are the drinks made without distillation of the fermented broth.
Option (3) Whisky and rum are produced without distillation of the fermented broth. — Incorrect. Whisky and rum, like brandy, are produced by distillation of the fermented broth. Saying they are made without distillation is wrong.
Since statements (1) and (2) are both correct and (3) is wrong, Option (4) is the answer.
