Slice strawberries and add to a large pitcher. Add blueberries and lime juice.
Sprinkle with sugar if using. Let sit for about 10 minutes so the strawberries release their juices.
Stir in wine and triple sec if using. Cover and refrigerate for at least 4 hours or up to 24 hours.
When ready to serve, stir in chilled sparkling water or club soda. Serve chilled and/or over ice. Enjoy!
*If you don't have a large enough pitcher, you can fill your serving glass with half sangria and half sparkling water. (This is also a good idea if you won't be drinking all of the sangria within a few hours after pouring in the sparkling water)*A lighter, fruitier, young wine is best for sangria to complement the fruit in the drink.
