Prepare the Watermelon Juice:

Take about 3 cups of the cubed watermelon and blend it until smooth. Strain the juice through a fine mesh sieve to remove any pulp and seeds, if necessary.

Mix the Sangria:

In a large pitcher, combine the Moscato wine, vodka, and triple sec. Stir in the freshly strained watermelon juice. Mix well to ensure all the alcohol and juice are well combined.

Add Fruits and Remaining Watermelon:

Add the sliced lime and orange to the pitcher. Then add the remaining 4 cups of watermelon cubes.

Chill:

Refrigerate the sangria for at least 4 hours, ideally overnight. This allows the flavors to meld together and the fruit to soak up some of the alcohol.

Serve:

Serve the sangria chilled, with plenty of the fruit and watermelon cubes in each glass. If desired, add a splash of soda water to each serving for a little fizz.

Garnish (Optional):

Garnish with a sprig of mint or a slice of lime on the rim of the glass for an extra touch of summer.
