Re: wine -- I'm withholding judgment on screw tops until some high-quality wines have been aged with them (and that's now happening). But as for corks, give me the synthetic ones -- about 3%-5% of real-corked bottles are tainted by TCA contamination. That's one out of every 20-30 bottles. I just hate it when that happens! Glad I don't have to worry about it with bourbon.
