Done well, mulled wine is a winter highlight — gently spiced and warming, it's a perfect antidote for chilly evenings. More often than not, it can be cloyingly sweet and an excuse to offload cheap "wine" onto guests. This recipe is stripped back. It uses a finer wine and has a hint of sweetness. Warming spices are at the forefront, and the wine doesn't get lost... there's no disguising chemicals here!
