Oak chips are a source of ellagic (wood) tannin. The level of tannin available will differ depending upon the wood source and the treatment regime. When using oak based products, macromolecules (lignin, cellulose, hemicellulose, etc.) other than oak will
be extracted. The oak based addition may help mask flavors, provide some oxidative protection and leave an oak finish, but they will NOT improve mid-palate structure. By contrast, the combination of wood and proanthocyanidic tannins in FT Rougeor FT Rouge Soft will help improve structure and color stability.
