That would be great if the glass in wine bottles were thick enough to handle carbonating beer.... And sorry, it isn't. (remind me to tell you the story of the 4 cases of wine bottles taking up space in my beer cave the next time you can't sleep)
Still cider or something else that isn't carbonated would work nicely in those bottles.
