Notes
The flavor of your frozen sangria will depend greatly on the type of wine you choose, how much sweetener you add, and whether you use orange liqueur or brandy, or leave it out entirely.
Vary the fruit: Try different combinations of berries, or just one kind of berry. Try a couple of tangerines instead of an orange.
Make white frozen sangria using white wine and frozen tropical fruit blends.
