1 bottle of reisling wine (750 mL)
2 cups guava juice
1 cup diced mango
1 cup pineapple tidbits
1 cup sliced strawberries
1-2 shots of coconut rum

Mix all of the ingredients together and serve well-chilled or over ice.
Top with additional diced fruit.
(With my various sangria, I chopped up a few different fruits that my guests could add to their glass including diced pear, apple, orange, lime, and peaches.)
