We received a bottle of Dom last Christmas from a client. We haven't opened it yet, we wanted to save it for a special occassion. We had a "friend" over recently who is a bit of a lush and as he was working his way through my liquor cabinet he came upon it. Through his drunken stupor, he tried to convince me that champagne is not like wine, and will go bad if we did not drink it soon. I said no and now I'm wondering, is he right or was this just a ploy to have me open it?
