This Riedel O tumber is designed for Chardonnay wine. Maximilian Riedel (11th generation) presents his first glass series. 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! The designs of “O” are based on the benchmark shapes of Riedel Vinum.
