he most widely planted grape in Italy is Sangiovese, a high-acid grape with moderate to high tannins, apparent earthiness and subtle fruit. It is thought to have originated in Tuscany and its name, which translates to "blood of Jove," leads historians to believe it may date all the way back to the Etruscan period, though historical mentions only go as far back as the early 1700s. Though planted all over modern Italy, the most significant wines made from Sangiovese still come from Tuscany: Chianti and Brunello di Montalcino. Sangiovese must make up 75% of a blend from the Chianti DOCG t be labeled as such, traditionally allowing for Canaiolo, Trebbiano and Malvasia for the remainder, though more recently small proportions of Cabernet Sauvignon or Merlot have been allowed. In Brunello di Montalcino the wine must be made entirely of Sangiovese. Prugnolo is Montepulciano's name for Sangiovese, and it is used there for the Vino Nobile di Montepulciano wines. In the DOC of Carmignano Sangiovese can be blended with 20% Cabernet Sauvignon. There are also Super Tuscans, IGT wines that blend Sangiovese with large proportions of Cabernet or Merlot. Elsewhere in Italy it is a workhorse grape, though it does find some success (though not the longevity) in the Montefalco and Torgiano wines of Umbria as well as the foundation of Rosso Piceno and a significant element of Rosso Conero from the Marches. Like Nebbiolo, Sangiovese has struggled to find footing outside of Italy, though in recent years California wineries have been having better fortune with grape plantings in the Sierra Foothills/El Dorado County, as well as Sonoma County and the Central Coast.
