Today's Amazon Friday Sale lists a number of six-packs of Riedel Vinum stemware for $39.99 down from $95.20. Available shapes at this special price (today only) include burgundy/pinot noir, chablis/chardonnay, chianti classico/riesling, sauvignon blanc and syrah/rhone. I've got several of these shapes and can recommend them enthusiastically.
Click the link below, scroll down and enter "Vinum" in the Amazon search box midway down on the right side. Chowhound will get a percentage of sales through this link -- it's only a small amount, but every little bit helps. Anyone looking for great wineglasses can get a super deal and support the site at the same time.
