Place the cinnamon sticks, cloves and allspice on a double thickness of cheesecloth; bring up the corners and tie with string to form a bag. Place in a large saucepan with apple juice (or place loose spices in pan and strain before serving). Bring to a boil. Reduce heat; cover and simmer for 30 minutes. Remove spice bag. Serve punch hot in mugs. Garnish with cinnamon sticks if desired.
