Which pairing is correct?

  • A.Pediococcus damnosus with the malting of barley grain
  • B.Oenococcus oeni with malolactic fermentation
  • C.Acetobacter aceti with the alcoholic fermentation of must
  • D.Botrytis cinerea with the bittering of beer wort

Answer: B

Only the first pairing holds. Acetobacter spoils wine by making acetic acid, Botrytis is a vineyard fungus with nothing to do with hops, and Pediococcus is a beer spoilage organism rather than anything to do with malting.
