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 machine-made Pinot Noir glass of the technologically advanced glass collection Performance is the new ultimate loudspeaker for fine wine. The shape of the bowl supports peatiness flavor and the taste of plum of these sensual red wines. Lightweight, durable and dishwasher safe, performance glasses are executed in sparkling fine crystal, and feature long fine stems and large stable bases.
