Wine glasses... have lots of Riedel (Vinum Extreme range, mostly) collected while we were in Japan. 6 of each, in a variety of shapes and sizes.
However, our day-to-day glass, and the brand we would adopt now if we were starting a collection is Zalto. Much more delicate in appearance, finer glass, but also dishwasher safe and not prone to going cloudy as a result. Their Universal glass works well for everything apart from sparkling and dessert wines. Not cheap to buy, but have proved to have decent longevity (apart from when a plate slid into a glass stem in the dishwasher).
