Question

Who reported that height-aspect-ratio is linked with perturbations in beer flavour?

(a) Hoggan

(b) Shardlow

(c) Vrieling

(d) Ulenberg

I had been asked this question during a job interview.

I'd like to ask this question from Properties of Fermentation Vessels topic in portion Fermentation System & Management of Fermentation Technology

Answer 1

The correct option is (c) Vrieling

For explanation I would say: Vrieling in 1978 reported that height-aspect-ratio is linked with perturbations in beer flavour.  The concentrations of the important flavour compounds, ethyl acetate and isoamyl acetate, formed during fermentation is inversely related to the height of the vessel.
