The riesling/sauvignon blanc glass is perfect for balancing the high acidity and residual sugar of fruit-forward white wines. This shape is the most versatile white wine glass in the Riedel range. It helps to balance the fresh characters and high mineral components, emphasising the wonderful fruit aromas. Designed in 2004, the Riedel O 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. Machine-made and dishwasher safe. This pack contains 2 pieces.
