Slice strawberries, pineapple, and lime into small pieces.
Add wine to a large pitcher.
Pour in vodka, grenadine, lime juice, and orange juice.
Stir well with a wooden spoon.
Add fruit slices and let the mix chill in the fridge for 1–2 hours.
Just before serving, add soda for fizz.
Fill glasses with ice and pour sangria over top.
Garnish with an extra strawberry or lime slice.
Notes
Use fresh fruit for the best flavor and color. Adjust sweetness with grenadine or simple syrup as desired. For a stronger cocktail, add more vodka; for a lighter one, increase the soda. Rim glasses with sugar for a festive touch.
