Performance Champagne - 2-Pack is a beautiful champagne glass in a set of two from the brand Riedel. The glass is part of the Performance series and like other products from the same series, the glass is made of thin crystal glass. This Champagne glass has been designed specifically for the bubbles in Champagne and other sparkling drinks, such as Prosecco and Cava. The shape of the glass with a pointed bottom, a wider centre and a smaller opening focuses on the flavours and aromas of the wine.
