“A meal without wine is breakfast”

“A meal without wine is breakfast” is a saying of unknown origin, cited in print since at least the 1990s. Not everyone agrees with the saying—there are champagne and mimosa breakfasts.

There’s an old saying that “A meal without wine is breakfast.” I’m not sure who said it, but I have always wanted to pose a simple question. Have you not heard of Champagne? 
 
Yes, Champagne is a wine that knows no bounds when it comes to enjoyment at any time of day with a wide variety of culinary fare. Brunch — a celebratory special meal — is traditionally served a little later in the morning and was created around Champagne.
