Sangiovese
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 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.
The high acidity and light body characteristics of the Sangiovese grape can present a problem for winemaking. The grape also lacks some of the colour-creating phenolic compounds known as acylated anthocyanins. Modern winemakers have devised many techniques trying to find ways to add body and texture to Sangiovese - ranging from using grapes that come from extremely low yielding vines, to adjusting the temperature and length of fermentation and employing extensive oak treatment. One historical technique is the blending of other grape varieties with Sangiovese, in order to complement its attractive qualities and fill in the gaps of some of its weaker points. The Sangiovese-based wines of Chianti have a long tradition of liberally employed blending partners—such as Canaiolo, Ciliegiolo, Mammolo, Colorino and even the white wine grapes like Trebbiano and Malvasia. Since the late 20th century, Bordeaux grapes, most notably Cabernet Sauvignon, have been a favoured blending partner though in many Italian DOC/DOCG regions there is often a maximum limit on the amount of other varietals that can be blended with Sangiovese; in Chianti the limit for Cabernet is 15%.
Other techniques used to improve the quality of Sangiovese include extending the maceration period from 7–12 days to 3–4 weeks to give the must more time to leach vital phenols out of the grape skins. Transferring the wine during fermentation into new oak barrels for malolactic fermentation gives greater polymerisation of the tannins and contributes to a softer, rounder mouthfeel. Additionally, Sangiovese has shown itself to be a "sponge" for soaking up sweet vanilla and other oak compounds from the barrel. For aging the wine, some modern producers will utilize new French oak barrels but there is a tradition of using large, used oak botti barrels that hold five to six hectolitres of wine. Some traditional producers still use the old chestnut barrels in their cellars.
