• 2 large lemons, sliced
• 2 3" pieces ginger, peeled, thinly sliced
• 6 2"-long cinnamon sticks
• 6 cardamom pods, lightly crushed
• ¼ tsp. kosher salt
• 2 750-ml bottles dry red wine
• 4–6 12-oz. cans chilled Coca-Cola
• Lemon wedges (for serving)

Combine 2 large lemons, sliced, two 3" pieces ginger, peeled, thinly sliced, six 2"-long cinnamon sticks, 6 cardamom pods, lightly crushed, ¼ tsp. kosher salt, and two 750-ml bottles dry red wine in a medium pot, cover, and bring to a simmer over medium heat. Cook, still covered, adjusting heat as needed to maintain a gentle simmer, 10 minutes. Pour wine mixture into a large bowl; cover and chill until very cold, at least 2 hours and up to 2 days.Just before serving, strain wine mixture into a large pitcher; discard solids. Pour into tall ice-filled glasses, filling about halfway. Pour in four–six 12-oz. cans chilled Coca-Cola to fill the rest of the way; garnish with lemon wedges.
