A delicious warming drink, based on the Italian Vin Brûlé. It's Perfect for serving to guests at your next Christmas party, or to treat yourself while you're wrapping the Christmas presents!
You can either serve this immediately, or prepare ahead and reheat gently later. If you are serving the wine in individual glasses, then you could pop a thin slice of orange into each glass. If you are preparing a large pot for guests to help themselves from, then add the slices to the pot just before serving.
