"The champagne flute is a stem glass with a tall, narrow bowl. The bowl of a flute may resemble a narrow wine glass as seen in the illustration; or a trumpet shape; or be very narrow and straight-sided. As with other stemware, the stem allows the drinker to hold the glass without affecting the temperature of the drink. The bowl is designed to retain champagne's signature carbonation, by reducing the surface area at the opening of the bowl. The flute has largely replaced the champagne coupe or saucer, the shape of which allowed carbonation to dissipate even more rapidly than from a standard wine glass. Its smaller diameter also allows more flutes to be carried on a tray."
