Abstract:  The wine made by Huaxia winery Co. Ltd. in 2004 was used as raw material to study the changes of flavan-3-ols and proanthocyanidins during aging in American oak, Europen oak, or Occident oak barrel. After the aging in the oak barrel, the concentration of (-)-epicatechin (EC), (-)-epicatechin gallate (ECG), and (-)-epigallocatechin gallate (EGCG) increased, whereas that of (-)-epigallocatechin (EGC) slightly decreased. The content and mean degree of polymerization (mDP) of proanthocyanidins decreased, and the composition changed accordingly.
