The optic impact in the Riedel Performance series adds both a design feature and an astounding effect on wine's aromatics.  Riedel Performance is the first wine glass series ever to feature bowls with a light optic impact for better aromatics. Co-designed by both Georg and Maximilian Riedel, Riedel Performance is a technologically advanced and user-friendly collection of grape varietal-specific glasses. “premium” defines the advantage of machine-blown Riedel glass vs. hand-made glass.
