Well, the main concept behind the Riedel glassware designs is that they focus the flavour profile of particular grape varietals to the proper areas of our tongue, so we taste the wines better, or more precisely, what the grape has to offer, and how the producer has treated it. Check out
www.riedelcrystal.com. The coolest thing on the site is the "choose your glass" option. Just choose a beverage, and it will suggest an ideal glass in all their stemware series. I have to say, the theory behind the glassware is true. If we are just drinking, any glass will do, but when we taste for real at home, or do a tutored tasting for a client, we use the proper Riedel glasses.
