What is the difference between a Champagne coupe and a Champagne flute?
For 300 years or so, Champagne was served in a wide, flat glass known as a coupe. When bubbles first appeared in wine, they were not seen as desirable, so this style was perfect: the wide shape of the glass caused the bubbles to disappear quickly. As effervescence became more sought-after, the tall, narrow Champagne flute took over as it preserves the bubbles longer. These days, Champagne is sometimes served in a more traditional white wine glass, as this shape allows the aromas of the wines (the nose) to be more fully developed.
