The Salem Cross Inn makes mulled wine with iron rods called loggerheads that have been heated over the fire. These are gently plunged into the liquid to heat it up and marry the flavors of the spices.
Combine all ingredients except the cinnamon sticks in a very large enameled metal pitcher (you can also use a smaller metal pitcher and heat the wine in batches, but do not use glass or plastic as the heat could cause them to crack or melt). Submerge a loggerhead in the wine mixture until hot, about 30 seconds or less. Pour into wine glasses and garnish each with a cinnamon stick.
