Question

Which of the following is an appropriate reason which brought a need for secondary fermentation?

(a) High carbonation level

(b) Low carbonation level

(c) High oxygenation level

(d) Low oxygenation level

I had been asked this question during a job interview.

Asked question is from Secondary Fermentation topic in portion Fermentation System & Management of Fermentation Technology

Answer 1

Correct choice is (b) Low carbonation level

Easy explanation: There was relatively low carbonation level achieved in shallow open fermenters which brought a need for a separate secondary fermentation. The high amount of additional carbon dioxide was purely generated in the secondary fermentation.
