Question

Which of the following is not an advantage of high-gravity brewing?

(a) The capacity of fermentation is increased

(b) Low energy usage

(c) Less labour

(d) High precipitation of protein

This question was addressed to me in homework.

Enquiry is from High Gravity Brewing and Glossary topic in section SCADA System for Bioreactors, Beer and Brewing of Fermentation Technology

Answer 1

The correct option is (d) High precipitation of protein

To elaborate: The main advantage of high-gravity brewing is that the fermentation capacity is increased with no need for capital expenditure. Many other advantages include reductions in both energy usage and labour costs. The high concentrations of ethanol are formed with promotes increased precipitation of polyphenol protein material.
