Making your Strawberry Peach Sangria is incredibly straightforward. Follow these simple steps:

1. Prepare the Fruits: In a medium bowl, combine the sliced strawberries and peaches. If using nectarines, prepare them in the same manner.
2. Add Sugar: Sprinkle the granulated sugar over the fruit and toss gently to coat. Let this sit for about 5-10 minutes, allowing the fruits to release their juices.
3. Mix the Wine and Schnapps: In a large pitcher, pour the bottle of white wine and peach schnapps. Stir gently to combine.
4. Combine Fruit and Liquid: Add the macerated strawberries and peaches to the pitcher with wine mixture. Stir gently to incorporate everything.
5. Chill the Sangria: Cover the pitcher and refrigerate for at least 2 hours. This waiting time allows the flavors to meld beautifully.
6. Serve with Bubbles: Just before serving, add soda water or lemon-lime soda for a fizzy lift. Adjust the amount based on your preference for sweetness.
7. Prepare for Serving: Fill glasses with ice cubes, then pour the sangria over the top, ensuring each glass has a generous amount of fruit.
8. Garnish and Enjoy: For the final touch, garnish with fresh mint leaves before serving. Enjoy your Strawberry Peach Sangria chilled!
