Step 1

Place 1/2 cup of unsweetened cranberry juice and 1/4 cup granulated sugar in a large, microwave-safe measuring cup or medium bowl. Microwave in 15-second intervals, whisking in between each, until the sugar is dissolved, about 45 seconds total. Add the remaining 1 cup cranberry juice and whisk to combine.

Step 2

Halve 1 medium orange, then cut each half into thin half-moons. Place 8 cups ice, 1 1/2 cups Pimm’s, and the sweetened cranberry juice in a 4 1/2-quart or larger pitcher and stir to combine. Add the orange slices, 1 (12-ounce) bottle chilled hard apple cider, 1 (12-ounce) bottle chilled ginger beer, and 1 cup fresh or frozen cranberries. Stir to combine.

Step 3

Pour into glasses, adding ice, cranberries, and orange slices from the pitcher to each glass. Garnish each glass with a cinnamon stick and rosemary sprig if desired.
