He’s got a blog where he addressed this question a bit, you might want to look it up. As I recall, he liked the Riedel Pinot XL for the rose, and the Riedel Riesling for the “regular” cuvee.
I have the Zalto White wine glass, which is a lot like the Riesling, and I really like Champers out of them.
I have indeed already addressed these questions in my blog, with two blog entries: Riedel Pinot Noit Vinum XL and Of Wine Glasses. However if you have more precise questions I will be happy to answer them.
