Designed in 2004, RIEDEL The O Wine Tumbler was the first varietal-specific wine tumbler in history. O is an innovative take on the casual wine glass, based on the benchmark shapes of RIEDEL's Vinum series. Better yet, the O Tumbler fits into every dishwasher so broken stems are a thing of the past.

The Syrah/Shiraz glass is perfect for balancing the gripping tannins and concentrated fruit typical of medium-bodied red wines. This shape was developed between 1993-1995 following sensory workshops in major Shiraz growing regions and has become the most versatile red wine shape in the RIEDEL range. With a slightly tapered opening, the large bowl develops the intense aromas, and demonstrates mouth filling fruit, dignified structure, and a long, sweet finish on the palate.
