Riedel Ouverture
I've tried a lot of different glasses over the years including the high end Riedels. I've settled on the Riedel Ouverture Red Wine glass. I use it for all types of wine. They are $31.96 for 4 at Amazon so you don't get upset when one breaks in the dishwasher and you can stock a lot for parties. They are much more durable than the more expensive Riedel lines.
Additionally, at wine tasting competitions they use a specific glass size and shape set by ISO (believe it or not!) These glasses match that size almost exactly.
