Yes, wine glasses really can make a big difference in how wine tastes. In principle, you can use anything to drink wine out of and if you’re drinking especially cheap wine, it’s unlikely that your choice of glass will make much difference. To really get the most out of good wine, though, you should pick your wine glass with care and attention. The more care you give to buying and tasting wine, the more care you should give to having the right wine glasses.
Although it might seem like nothing more than an excuse for snobbery, experience has shown over and over that higher quality glasses can have a big impact on how wine tastes. Apparently, it’s possible for the exact same wine to taste completely different to people if simply served in wine glasses made from different material.
one has been able to determine if this is merely a matter of aesthetics or if there is an actual physical reaction between wine and quality glass that doesn’t occur with wine and plastic or wine and lower quality glass. The best explanation offered so far is that crystal is rougher than regular glass and this roughness creates turbulence in the wine which, in turn, causes more of the aromatic compounds in the wine to be released.
