Which vessel material has traditionally been used to mature wine and to influence its flavour?

  • A.Ordinary window glass
  • B.Woven straw baskets
  • C.Oak
  • D.Plain untreated iron

Answer: C

Oak barrels contribute vanillin, tannin and other compounds while permitting a slow ingress of oxygen that matures the wine. They are also, unfortunately, a favourite refuge of Brettanomyces, which is one reason barrel hygiene matters.
