Trumpet glasses
 
Trumpet glasses feature sides that flare outward, resembling a trumpet. The flare allows for the faster release of aroma. 

 
Tulip glasses 
 
The widest in the middle of the bowl with a rim that curves inward; a form that directs the taste of champagne to the center of the tongue for best balance of fruit and acid, and concentrates the bouquet.  It is a glass preferred by wine connoisseurs. It focuses the aromatics towards the nose. Tulips are often used for finer French champagnes, as its wider base allows the flavor to be captured.

 
Flute
 
Flute also known as Trumpet glasses
have long, narrow bowls. The shape of the bottom of the glass, which is usually pointed, allows the slow rise of bubbles, and prolongs the cool temperature, maintaining aroma and flavor. The shape also focuses the aromatics towards the nose.  
 

Coupe glasses
 
Coupe, Saucer, Sherbet, have wide, shallow bowls. The coupe champagne glass was invented in 1663 in England by glassmakers looking to cash in on the “new” popular drink – "champagne."
 
The glasses do not work well because they enable aroma and carbonation to escape quickly.  The glass is  falsely attributed to being molded after the breast of Marie Antoinette (1755-1793).  In actuality, Marie created a milk drinking bowl made from a mold of her left breast to use at her Pleasure Dairy at Rambouillet.
