From the company who introduced the world to a revolutionary concept in wine glasses, the Vinum Series, comes another great wine revolution: The "O" Wine Tumbler. Enjoy the same great shapes you've come to know and love, but in a "stemless" variety.

The tumbler, used for centuries as an all-round drinking vessel, is now turned into a sophisticated wine accessory.

The designs of Riedel "O" are based on the benchmark shapes of Riedel Vinum. For the first time in glass history the design parameters such as shape of tumbler, size and diameter of rim, have been fine tuned to enhance the world’s most important grape varietals.

"O" is a non lead machine-blown series.

These 21 oz. glasses are recommended for Cabernet and Merlot wines.
