I'm with Paul on all that but I do make red wine vinegar also. If you
are sure it's acetone I do think it's usefulness as a wine barrel is
over but it's usefulness as a vinegar barrel has just begun.
Everything that makes a small barrel a pain for wine plays to
vinegar. Homemade vinegar is pretty awesome.
I know this sounds like a huge waste but the only thing I can think of
to recover them is to take them apart, scrape them to bare wood and re-
toast.
