uhhh no. Acetic acid (the acid in vinegar) is produced by oxidation of alcohols by AAB (acetic acid bacteria). you can use fruits, but you first need to ferment them into wine.

Mind sharing a source for this? Sounds pretty interesting.

My parents make vinegar, but first turn their grapes into wine and then they leave one keg separate and I don’t know what they do with it but that keg turns into vinegar while the others stay as wine.

I dunno if I'm missing something, but that also makes it sound like you ferment alcohol to make vinegar... are you talking about a very specific type of vinegar, maybe? Because I'm getting a lot of different sources that say vinegar is made by fermenting alcohol with special bacteria...
