Champagne coupes, also known as champagne saucers, were the original style of glass designed for serving champagne. Their wide, shallow bowl was believed to allow the champagne to cool more slowly and to enhance the aroma of the wine. While the exact origin of the coupe shape is debated, it gained significant popularity in the early 20th century, particularly during the Art Deco period. Such hand-cut Art Deco liqueur glasses were often used for special occasions and were considered a sign of elegance and refinement.
