Champagne stemware refers to the flute and coupe glasses used in the consumption of champagne, other sparkling wines, and certain beers. As with other stemware, the stem allows the drinker to hold the glass without affecting the temperature of the drink.

Champagne flute

The champagne flute (French: flûte à champagne) is a stem glass with a tall, narrow bowl, generally holding about 6 to 10 US fl oz (180 to 300 ml) of liquid.

The champagne flute was developed along with other wine stemware in the early 1700s as the preferred drinking vessel for wine shifted from metal and ceramic to glassware. Initially, the flute was tall, conical, and slender. By the 20th century, however, the shape preferred by glassware purchasers had changed from a straight-sided glass to one which curved inward slightly near the lip.

The bowl is designed to retain champagne's signature carbonation by reducing the surface area at the opening of the bowl.Nucleation in a champagne glass helps form the bubbles seen in champagne. Too much nucleation will cause the carbonation to fizzle out quickly. A smoother surface area will produce fewer bubbles in the glass and thus more bubble texture in the taster's mouth. Flutes, with their deep bowl, allow for greater visual effect of bubbles rising through the liquid to the top. The flute also helps regulate and reduce the oxygen-to-wine ratio, which both enhances the aroma of the wine as well as the taste.
