Sangiovese is a red Italian wine grape variety that derives its name from the Latin sanguis Jovis, "the blood of Jupiter". Though it is the grape of most of central Italy from Romagna down to Lazio (the most widespread grape in Tuscany), Campania and Sicily, outside Italy it is most famous as the only component of Brunello di Montalcino and Rosso di Montalcino and the main component of the blends Chianti, Carmignano, Vino Nobile di Montepulciano and Morellino di Scansano, although it can also be used to make varietal wines such as Sangiovese di Romagna and the modern "Super Tuscan" wines like Tignanello.
Sangiovese was already well known by the 16th century. Recent DNA profiling by José Vouillamoz of the Istituto Agrario di San Michele all’Adige suggests that Sangiovese's ancestors are Ciliegiolo and Calabrese Montenuovo. The former is well known as an ancient variety in Tuscany, the latter is an almost-extinct relic from the Calabria, the toe of Italy. At least fourteen Sangiovese clones exist, of which Brunello is one of the best regarded. An attempt to classify the clones into Sangiovese grosso (including Brunello) and Sangiovese piccolo families has gained little evidential support.
Young Sangiovese has fresh fruity flavours of strawberry and a little spiciness, but it readily takes on oaky, even tarry, flavours when aged in barrels. While not as aromatic as other red wine varieties such as Pinot noir, Cabernet Sauvignon, and Syrah, Sangiovese often has a flavour profile of sour red cherries with earthy aromas and tea leaf notes. Wines made from Sangiovese usually have medium-plus tannins and high acidity
