Question

Beer may be produced by ________________

(a) Fermentation of rice

(b) Germination of rice

(c) Germination of barley

(d) Fermentation of grapes

This question was posed to me during an internship interview.

The above asked question is from Oxygen Uptake in Cell Cultures in chapter Mass Transfer of Bioprocess Engineering

Answer 1

The correct choice is (c) Germination of barley

The best I can explain: Malt extract is frequently used in the brewing of beer. Its production begins by germinating barley grain in a process known as malting, immersing barley in water to encourage the grain to sprout, then drying the barley to halt the progress when the sprouting begins.
