In Argentina one of the things we loved was that instead of mimosa's most of the hot brunch spots were offering "Campari Orange" -- which is simply Campari combined with fresh squeezed orange juice and ice. So good! We've started drinking them at home and it's easy to make it into more of an aperitif by adding sparkling white wine or sparkling water. It's definitely more on the sour/bitter spectrum but we love that. Cheers!
