Chemical structure of castavinols, where R = H, OH, or OCH3

Castavinols are natural phenolic compounds found in red wines.[1] These molecules are colorless and are derived from anthocyanin pigments. Thus their formation leads to a wine color loss.

Known molecules

  • Castavinol C2
  • Castavinol C3
  • Castavinol C4
