There is a difference between wine and champagne, as most of us know, and they serve different purposes. A glass of champagne with your dinner every night is a waste of money, and breaking out your best bottle of Sutter Home when your girlfriend accepts your marriage proposal is an insult to the occasion. Know the difference between the two and have a bottle of each on hand at any given time. You never know when your brother is going to stop by and say that he and his wife are expecting a child. You never know when your girlfriends mother, who hates the taste of beer, will come by for a visit. Be prepared. If you can't afford one of these champagnes, there are others that are more fiscally desirable.
