More often than not (and because I’m in the white/rosé wine camp), I make a white sangria.
For that, I usually add some frozen peaches and a mix of berries (raspberries, blueberries, blackberries, strawberries). Now that most of those fruit are in season, you can of course use fresh.
I like the frozen, as it also functions as a cooling agent
Splash of orange juice & often a goodly amount of prosecco, too. Very refreshing – I often have to make a new batch to satisfy demand '-)
I think a similar mix would work for rosé wine as well.
