So if different glass shapes affect the smell and taste of the same wine, should we have a dedicated glass shape for each and every varietal? At least one glass supplier, Riedel, advocates something along these lines, marketing an array of different glasses at extravagant prices for just about every wine variety you can think of. That’s probably OTT and you’ll certainly pay an arm and a leg for the privilege of flaunting the Riedel brand, quite apart from the daunting prospect of where exactly you are supposed tostore all these different shapes and sizes.Don’t get me wrong. The right shaped glassware can showcase the nuances of wine, especially in a variety as subtle as, say, Pinot Noir. But while it may be a lot of fun to have a huge bowled Merlot glass, another for Cabernet Sauvignon and a third for Gamey, what ‘s the best glass for say Chianti, which can be a blend of Sangiovese, Canaiolo and maybe even Merlot or Cabernet Sauvignon grapes?
