The 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. The O Wine Tumbler is the first varietal specific wine tumbler in history. O is an innovative take on the casual wine glass, giving total wine enjoyment. This wine glass series is based on the benchmark shapes of VINUM to enhance the world's most important grape varietals. The tumbler, used for centuries as an all round drinking vessel, is now turned into a sophisticated wine accessory. Broken stems are a thing of the past.
