Welcome to the Drinking Week
You can think of it as "Monday", or you can think of it as "Bodegas Paso Robles Rosé de Garnacha Day".
It's all in how you look at things. Sure, you can spend the day sighing about the weekend that just ended, and dreading another workaday week of working days all week. If you want to feel miserable, there's no law against it.
Or you can think of this as the day when Bodegas Paso Robles Rosé de Garnacha first came into your life. When you look at it like that, all those Monday hassles fade into a haze of watermelon, honeydew, and candied fruit, especially served ice cold.
We don't necessarily recommend starting the workweek by actually drinking it. But you're a grownup, do what you want.
