Sure, and at that point you get into the definition of beverage (is a mouldy bunch of grapes in a forest a beverage, if there's no one to drink it?).

I'd suggest that from a purely evolutionary perspective, honey bees predate grapes, and wild yeasts would certainly have turned an abandoned bee nest into an ad hoc mini-bar on more than one occasion during pre-modern history, but I feel I'm now veering way off from my challenge to that original claim.
