If wine that's stored in barrels after fermentation is exposed to too much air, what can it turn the wine into

Answer 1

Vinegar. If you open a bottle of wine and leave it open you can get the same thing, and it will also happen if the cork is allowed to dry out. This is why wine bottles with corks are stored with the corked end down, to keep the cork wet and prevent it from drying out and allowing air to pass through.

Answer 2

Ethanol gets oxidized slowly first to acetaldehyde (CH3CHO if u want to get technical), smells a little bit like acetone... further it gradually oxidized to acetic acid (CH3COOH) or well known as vinegar.

Beside that main component, other components and substances in wine would get oxidized too. This is very profound esp. in white wine, because most of the phenolic compounds in it more prone to oxidation that red wine. Also, many white wines are fermented in stainless steel vat, thus omitting barrel fermentation resulting in even more prone to oxygen attach wines.
