The design of glassware significantly impacts the experience of drinking sparkling wine. Historically, the wide, shallow 'coupe' glass was popular, famously rumored to be modeled after the breast of Marie Antoinette. However, the coupe has a large surface area that allows carbonation to escape quickly, causing the wine to go flat. In the mid-20th century, the 'flute' became the standard. Its tall, narrow shape is designed to preserve the 'bead' (the stream of bubbles) by minimizing the surface area. The height of the glass allows the bubbles to travel further, which helps concentrate the aromas and enhances the visual appeal. Modern connoisseurs sometimes prefer 'tulip' glasses, which combine the flute's bubble retention with a wider bowl to better express the wine's bouquet.
