Question

Which of the following results in a decrease in specific gravity of wort?

(a) Attenuation

(b) Ageing

(c) Cropping

(d) Hopping

I had been asked this question by my college director while I was bunking the class.

The doubt is from High Gravity Brewing and Glossary topic in division SCADA System for Bioreactors, Beer and Brewing of Fermentation Technology

Answer 1

Right option is (a) Attenuation

The explanation is: Attenuation is the process that results in a decrease in specific gravity of wort during fermentation. The rate in decline in gravity is known as attenuation rate and the specific gravity at the end of primary fermentation is known as attenuation gravity.
