Pour the white wine, orange juice, and triple sec into a large pitcher. Add the oranges and cinnamon sticks.
In a piece of cheesecloth that has been folded over 2 times, add the star anise and cloves. Tie with cotton twine to form a little package. Place into the pitcher and stir everything together.
Refrigerate for 15 minutes, or up to 2 hours, to allow the spices to infuse the wine. Remove and discard the spice packet. Serve over ice with garnishes of more orange slices and cinnamon sticks.
Notes
I used a Reisling but any white wine will do. I prefer sweeter wine for my sangrias, but use your favorite variety. Pinot Grigio and Moscato are also great choices.
