There's no formal title on Aurelio Montes' business card—neither president nor chairman, not even head winemaker. It simply reads "Guardian of the Spirit." One of Chile's most talented and peripatetic winemakers, Montes, 65, is among the fathers of Chile's modern wine revolution. His company, Viña Montes, which he started from scratch with three partners in 1988, now surpasses the 1 million case-production mark annually. Overall, the Montes brands are sold in 110 countries around the world. These achievements are yet more striking because Montes is a self-made man, on the short list of successful Chileans of the postwar generation who did not have the luxury of a family fortune to help them.
