Place the champagne in an ice bucket with a mixture of half ice and half water for about 25 minutes, or refrigerate the champagne for 3 or 4 hours. The taste and odor of the champagne is best if the temperature is approximately 45 degrees.
Remove enough foil to allow you to remove the twisted-wire cap. Keep your finger over the cork, as it can pop out involuntarily.
Ease the cork out gently by holding the cork and turning the bottle in one direction. Hold the bottle at a 45-degree angle pointing away from yourself and other people. The cork should come off with a "sigh."
Wipe the neck of the bottle with a clean linen cloth before pouring.
Serve champagne in tulip-shaped glasses or tall-fluted glasses. Pour about an inch into the glasses and allow the froth to settle. Top off the glasses, being careful not to over-fill. Return the bottle to the ice bucket until you are ready to serve again.
