In a large pot or dutch oven over medium-high heat, stir together water, sugar, cloves, cinnamon sticks and lemon peel. Bring to a boil.
Add lemon juice and red wine. Reduce heat to medium. Heat the wine mixture to 180°F (80°C), about 5-10 minutes. (Above that temperature, the alcohol will begin to cook out. We simply want to warm it.)
Reduce heat to low and let flavors infuse for 15 minutes more. Remove from heat.
When ready to serve, warm on low heat. Serve in mugs or insulated glasses. Garnish with an orange wedge and/or a cinnamon stick.
Store in an airtight container in the refrigerator for up to 2 weeks. Be sure to remove the fruits and spices, especially the lemon peel, which can add bitterness.
Notes
Storage tips: Store cooled mulled wine an airtight container in the refrigerator for up to 2 weeks. Be sure to remove the fruits and spices, especially the lemon peel, which can add bitterness.Non-alcoholic version: You can make a non-alcoholic version of Glühwein with grape juice for the kids and non-drinkers. Grape juice is very sweet on its own, add the sugar later after you've tasted it. Cranberry juice would also work, or a mixture of the two.
