Champagne and sparkling wine are different from wine in many ways. One difference is how to open the bottle. And now you will know how to properly open a Champagne bottle...
Make sure the bottle has been chilled.
Remove the foil from around the cork.
Place your hand on top of the bottle and carefully twist to remove the wire cage.
Hold on to the cork with one hand and the bottle with the other.
Slowly twist the bottle and hold on to the cork.
The goal is to make the least noise as possible.
Another adventurous way to open a bottle is with a large sword. Remove the foil and wire cage. Take the sword and quickly slide it across the vertical seam of the bottle towards the cork. This should break the end of the bottle. This method is a lot messier. I wouldn't recommend trying it for the first time at someone else's home. :)
When pouring the Champagne, tilt your tulip-shaped flute so that the Champagne falls on the side of the glass. Fill the glass half way and wait for any foam to settle. Now fill your glass about 2/3 of the way and cheers!
