Exposure to oxygen leads to oxidized wine which forms acetic acid and ethyl acetate yet there must be an acetic acid bacteria, like acetobacter or gluconobacter, present in the oxidizing wine in order to make the change to vinegar.
Even the FDA does not recognize acetic acid as vinegar. Vinegar is so much more than acetic acid. Acetic acid is described as vinegar-like.
I ferment vinegar and there is a big difference in a turned bottle of wine versus vinegar production, at least to me.
Interesting. I actually did not know this. I always just kind of lumped them together.
I guess in the future when someone asks about their brew turning to vinegar we will need to ask for clarification
