What is the problem with premature oxidation (premix) in Burgundy? What caused this? How can this be solved?
  • In the early 2000s the white wines were showing very advanced flavours and colours after a relatively short period of time in bottle.
  • The problem still exists but in less lower levels by modifying the wine making practices
  • Expected causes:
    • Changes in the vineyard; higher yields , different chemical composition of the grapes
    • Use of over-clean must due to pneumatic pressing,
    • overzealous battonage,
    • lower sulfite at bottling
    • quality and changes in cork treatment.


Some producers practice hyperoxidation to produce a wine less prone to oxidation.
