The term 'champagne holder' can refer to two different items: a FLUTE and a GLASS. A FLUTE is a tall, slender GLASS with a narrow stem and a wide bowl-shaped top, which is used to serve sparkling wines such as champagne. A GLASS is a wider, shorter GLASS with a stem and a bowl-shaped top, which is also used to serve sparkling wines. Both of these items are designed to hold champagne and other sparkling wines in order to maintain their carbonation and flavor.
