Mix all ingredients except wine and nutmeg in a 3-quart saucepan. Heat to boiling; reduce heat and cover. Simmer 15 minutes; strain.
Return to saucepan and stir in wine. Heat until hot. Pour into warmed mugs and sprinkle with nutmeg, and float a small slice of lemon if desired, or add a cinnamon stick. Makes 6 servings, about ¾ cup each.
