Cork taint in wine is caused by

  • A.Carbon dioxide dissolved from a second fermentation
  • B.Chloroanisoles formed by fungi acting on chlorophenols
  • C.Acetic acid produced by bacteria inside the bottle
  • D.Sulphur dioxide added at too high a concentration

Answer: B

Compounds such as trichloroanisole are detectable at extraordinarily low concentrations and give a musty, damp-cardboard smell that masks the fruit. It is a contamination of the closure rather than a fault of the fermentation.
