Never serve sherry in these offensive old style sherry scooners. If you have any, throw them away right now!
To fully appreciate the wines, I don't recommend the use of this small glass as it does not allow the wine to fully express itself; to appreciate the aroma or the full flavour of the wine.
I love Riedel, superb glasses. They really do make drinking wine more enjoyable. I would highly recommend them.
The traditional wine tasting glass (if it is large enough) is an ideal glass for Sherry served as an aperitif or dessert wine. However I recommend a good quality generic white wine glass with a generous bowl which will allow the wine to breathe and a long stem so that the wine stays cool. This is always the best choice of glass to enjoy Sherry at the table during the meal.
For my sherry drinking, I use the Riedel Ouverture White Wine glass. l find this the ideal glass, without breaking the bank.
