To hold a Champagne Flute, pinch the top of the stem between your thumb and forefinger. Your little finger should rest just above the base to ensure the crystal flute is steady. When holding a Champagne Coupe or Saucer, you should take a similar approach to the flute, pinching the stem in the same manner.
How do guys hold a champagne glass?
Always hold your champagne glass by the stem. Champagne is best enjoyed chilled and holding the glass or coupe by the bowl will warm the drink. The rim also works. A champagne glass or coupe should never be filled all the way up.
