RIEDEL The O Wine Tumbler, designed in 2004, was the first grape variety-specific tumbler in history. O is an innovative take on the casual wine glass, created from the distinctive shapes of RIEDEL's Vinum series. Furthermore, the O tumbler is suitable for every dishwasher: broken stems are now just a distant memory.
