The Champagne Glass is perfect for developing champagne's complex characteristics. This glass allows the wide range of aromatics to unfold. Unlike a flute, the egg-shaped design allows the complex layers to grow and intensify, and the larger rim diameter enables them to be released in a way which is not achieved with a narrow glass. The glass also includes a 'sparkling point' to aid the formation of the Champagne bubbles. As part of the Performance series, this shape was re-developed in 2018. This glass is perfect for light, fresh, dry champagnes, proseccos and sparkling wines. This piece is produced with clear crystal.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.This item is Premium machine-made. 'Premium' defines the advantage of a machine blown Riedel glass vs. a hand-made glass. The difference lies within the precision.
