Performance is the first RIEDEL wine glass series ever to feature bowls with a light optic impact, which not only adds a pleasing visual aspect to the bowl, but also increases the inner surface area. The shape of the glass optimal delivers the classic aromas of toast and black olives, which are typical for wines made of Shiraz grapes. On the palate, it brings out the wine's silky, velvety structure and balanced flavours. Lightweight, durable and dishwasher safe, performance glasses are executed in sparkling fine crystal, and feature long fine stems and large stable bases.
