Chili works really well with Cava, Grenache, and Shiraz. These juicy reds don't have too much tannin (important for spicy foods), but a sparkling wine like cava can tame the heat even better. The Cava Mestres Reserva Brut 1312 with a 4.6 out of 5 star rating seems like a good match. It costs about 19 dollars per bottle.
