Question

What do you mean by Racking?

(a) Removal of sweet wort

(b) Inoculation of wort with yeast

(c) Separation of green beer of yeast

(d) Method of raising the temperature

I had been asked this question in an online quiz.

My question is taken from High Gravity Brewing and Glossary in section SCADA System for Bioreactors, Beer and Brewing of Fermentation Technology

Answer 1

Correct answer is (c) Separation of green beer of yeast

For explanation: Racking is the method of separation of green beer of yeast. It is used to describe the process of emptying the fermentation vessels. Final gravity achieved at the end of primary fermentation is referred to as the ‘racking gravity’.
