I see a few issues. They aren't made for pressure, so no sparkling wines. Also if I remember they are hand blown glass with bubbles which may cause sanitation issues. Corking/sealing will probably be interesting as well. First two probably aren't a big deal, I'd be worried more about the last issue.
yeah, corks sealing are my main concern as well.
there seems to be enough of a neck there but not sure if it's absolutely straight or maybe slightly tapered.
might do cheap 1 gal batch of Apple juice wine & try just 1 bottle to see...unless someone who has tried & failed talks me out of it.
