You bet. In fact, you really should let the sangria refrigerate overnight. I don't recommend making this sangria at time of serving. At minimum, give the sangria four hours to chill, but overnight is best. Allowing this homemade peach sangria to sit in the refrigerator overnight gives the fruit flavors time to meld. The sangria is noticeably more delicious the day after it sits in the refrigerator, so you'll be glad you gave it time to work its magic. Plus, this make-ahead convenience is perfect for entertaining. Bonus.
