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. This glass allows the wide range of Champagne to unfold. The larger rim diameter enables the aromas of Champagne to be released, in a way which is not achieved when using a narrow flute. The glass also includes a 'sparkling point' to aid the formation of the Champagne bubbles. Lightweight, durable and dishwasher safe, performance glasses are executed in sparkling fine crystal, and feature long fine stems and large stable bases.
