Meet the O series, wine tumblers designed to perform just like preceding generations of Riedel wine glasses in a fun, casual form, and without the worry of breaking the stem. Maximilian J. Riedel designed the tumbler bowls to emphasize the rich, dark fruits and balance the tannins in red wines, and to be durable, elegant, and dishwasher safe.

The tumblers in Riedel O Series, like the Riedel O Pinot Noir/Burgandy, the Riedel O Chardonnay/ Viognier, and Riedel O Sauvignon Blanc/Riesling, match the shape to the grape and are resemblant of Vinum glasses. The Big O, the new generation of the O wine tumbler series, is a precision instrument tailored for wines made from Cabernet Sauvignon, Cabernet Franc or Merlot. The Riedel O Collection even includes the O to Go, a way to transport good glassware and your love of wine anywhere you go.
