I don't have the knowledge to answer your first question but i often make vinegar and the wine must be exposed to air for along period of time the get vinegar. I use a vinegar that contains mother to get the transformation going.
I guess I am a bad boy but i also use the brew belt on my glass carboys. I also have a small adjustable electric blanket that i place under my carboys when needed.
I will be very interested in learning about this ascorbic acid to prevent oxidation
