I know this was an old thread but it was locked and I thought it was time to bring it back up again. I like cork I think it's classier and screw tops are cheap. But as has been discussed on here long term storage with screw tops can resulted in evaporation. Unless it was waxed but long term storage with cork can result in cork taint. What every one's opinion last time everyone was in favor of screw on. I was surprised that at whisky magazine they were having this same discussion gave me the idea for this one and they overwhelmingly chose screw on for scotch. By the way I've never had a bad cork.
