aged champagne

[missy]

I have a bottle of champagne that was given to me for my 21st birthday. It is 11 years old waiting for a special occasion to be drank. I was thinking the celebration of a new century is good enough to drink this. First, is the champagne still good? it is not the best brand (cook) - it has been chilling for 5 years (collecting dust in my fridge) I am a normal Korbel drinker, I just want to make sure this bottle of Cook will not be skunky before I offer it to my friends.
