In Spain, as in much of Europe, there is a long tradition of blending wine with fruits and spices. The most famous example is sangría. There's also the spiced wine punch Hippocras (Hipocrás, o garrapiñado). But both sangría and hipocrás are chilled and best for the warm months. Late fall and winter, especially during the holidays, is time for a Spanish hot spiced wine, vino caliente.
It goes very well with roasted chestnuts.
Spanish-style hot spiced wine is easy. It takes just a few minutes to make. You'll need only an inexpensive red table wine--nothing fancy. It's the perfect holiday drink for a casual get-together of family or friends.
