A suggestion for this weekend's festivities: be lazy.
So lazy.
Look, I love making sangria from scratch. Mostly I love how it tastes, but it's also fun customizing your own blends with whatever fruits are in season at the moment. But when you're talking about serving in bulk, sangria transforms from "adorable homemade touch" to "enormous pain in the butt."
