The Riedel connoisseur will be surprised to find that this new glass series has something missing - there is no stem or base. Riedel 'O' is the new innovative take on the wine tumbler. In short: 'O' is the ideal glass for every day use and for every occasion. It is fun, feels good to hold, looks trendy and it works! Recommended for Riesling, Sauvignon Blanc, 13 1/4oz. Each.
