1 Add a cup of frozen blackberries and an entire sliced orange into a large pitcher.
2 Pour red wine, cranberry juice, pomegranate liqueur, blackberry syrup, and freshly squeezed lemon juice over the blackberries.
3 Stir to combine the ingredients and flavors.
4 Let the sangria sit in the refrigerator for at least an hour before serving. This resting time gives the fruit and alcohol time to permeate the sangria and amplify the flavors.
5 Pour over ice and garnish with orange slices.
