Combine the wine, apple cider, apple and pear brandies, Cinnamon Simple Syrup, cinnamon sticks, Gala and Granny Smith apples, red and green pears, oranges and pomegranate seeds in a large container with a lid. Refrigerate for at least 4 hours and up to 72 hours. Transfer to a pitcher before serving. Serve in red wine goblets over ice, if desired.
Combine the sugar and 1 cup water in a small saucepan. Bring to a boil over high heat and cook until the sugar is completely dissolved, about 3 minutes. Transfer the syrup to a lidded container, add the cinnamon sticks and let chill in the refrigerator for at least 4 hours and up to 48 hours -- the longer, the more intense the flavor. Remove the cinnamon sticks and save for the sangria.
