Here's my strategy for people who have a vice.....I usually take two strips of thin wood (i dont like the idea of the metal clamping on the glass) and put the bottle between them in the vice. Tighten carefully but of course not too tight. Then use pliers to unscrew the bottle. If done carefully, it doesnt take much effort at all to get the cap off. I don't think I've ever broken a bottle.
