My favorite thing about sangria, the Spanish punch, isn't actually the wine or spirits; it's the luscious assortment of fruit that gets ladled into each glass. I love how refreshing it is to sip, and munch, on a warm day, and I've often felt bad that my teetotaling partner hasn't been able to enjoy it. I developed this non-alcoholic version with him in mind, and discovered that I like it just as much as the real thing.
There are thousands of recipes for sangria, each using a different combination of wine and fruit, so I don't worry too much about whether this one is "authentic." For the fruit, I like to use the ample supply of citrus in my local markets and gardens – thin slices of oranges, lemons, limes – plus an apple for crunch. You could also try fresh fruits, like strawberries, pineapple, or grapes. When steeped for several hours, the fruits both flavor the drink and soak up the liquid, turning plump and juicy. They not only look pretty in the glass, but are a delight to eat.
