"Les Impitoyables" (The Uncompromising) glasses have been specially designed to maximize the pleasure of tasting wine. Each glass is designed for a type of wine to bring out its particular aroma and taste. The bases and stems are completely handmade. The bowls of each glass are individually blown, ensuring a consistent and appropriate shape. All are authenticated by the signature at the base of the glass. Peugeot Les Impitoyables Champagne glasses are for sparkling wines and champagne. The dimpled design on the outside of the Peugeot Les Impitoyables Champagne glasses causes light to refract. Featuring an elliptical curve of the glass, with the apex a third up the bowl, combined with a deep 'V' at the stem encourages the carbon dioxide to continually effervesce and brings the aromas of the wine quickly to the nose. Base and stem are handmade; the bowl is individually blown, ensuring a consistent and appropriate shape.
