Bistecca alla Fiorentina Doc. Cantinetta Rignana is nestled in the heart of Chianti grapevines. A rogue vine was trailing over my head. It’s a destination down a long dirt road, but worth it for sultry ravioli and fresh truffles and steak. If you’re going to eat meat, this is the place, with a side of sautéed spinach in pepperoncino.
