How oak and oxygen enhance red wine characters
The following points are based on available research world-wide:

1. Extracted oak compounds may help solubilize procyanidins and maintain a stability of monomeric anthocyanins (act as co-factors).

2. Aldehyde compounds extracted from toasted oak products can react in much the same manner as acetaldehyde to crosslink the anthocyanins and procyanidin monomers and oligomers (act as cross-linkers).

3. Covalent bonds formed with these compounds are more stable than those formed with acetaldehyde.

4. Oligomers formed through crosslinking have been shown to be structurally different, possibly more soluble than natural seeds and skin oligomers and polymers.
