Bring a pot of water to a boil. Once the water boils, add the peaches, submerging them in the water for 1 minute. Then remove them from the water with a slotted spoon and submerge them in cold water.

Peel the skin off the peaches, cut them in half, and remove the pit. Slice two of the peaches, and set the others aside. Place the sliced peaches in a large container with a lid.

Slice half of the strawberries, and add them to the container with the sliced peaches. Hull the remaining strawberries and put them in a blender. Add the peaches you set aside, and blend until the fruit is pureed.

Add the lemonade concentrate and the vodka to the blender, and blend just enough to mix everything together.

Pour the fruit and vodka mixture over the fresh fruit, and refrigerate overnight.

When you are ready to serve the sangria, combine 2 cups of the fruit and vodka mixture with 1 bottle of sparkling rose. I like to make one batch at a time so that the sparkling rose doesn't get flat, but you could opt to make one big batch combining everything at once.
