The Spirits glass is perfect for harmonising the aroma and the taste of spirits, tempering the alcohol and the stringency of the palate and emphasizing the bouquet. The slim, flute-shaped bowl allows its contents a very small evaporation surface. 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. This product is machine-made. This item is dishwasher safe. This pack contains 2 pieces.
