context_page_description: 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, 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 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 and Sangiovese piccolo families has gained little evidential support.
context_section_description: Sangiovese has shown itself to be adaptable to many different types of vineyard soils but seems to thrive in soils with a high concentration of limestone, having the potential to produce elegant wines with forceful aromas. In the Chianti Classico region, Sangiovese thrives on the highly friable shale-clay soil known as galestro. In the Montalcino region, there is a high proportion of limestone-based alberese soils alternating with deposits of galestro. The lesser zones of the generic Chianti appellation are predominantly clay, which often produce as high quality of wine as alberese and galestro do.
  The grape requires a long growing season, as it buds early and is slow to ripen. The grape requires sufficient warmth to ripen fully, but too much warmth and its flavours can become diluted. Harvests in Italy have traditionally begun after September 29, with modern harvest often taking place in mid-late October. A longer growing season gives the grapes time to develop richness and potential body. However, in cool vintages this can result in the grapes having high levels of acidity and harsh, unripened tannins. In regions (like some areas of Tuscany) that are prone to rainfall in October, there is a risk for rot due to the Sangiovese grape's thin skin. In other areas, such as the dry conditions of the Columbia Valley AVA of Washington State, the grape has good resistance to drought conditions and often requires little irrigation.
  For the best quality, yields need to be kept in check as the vine is notably vigorous and prone to overproduction. In Chianti, most quality conscious producers limit their yields to 3 pounds (1.5 kg) of fruit per vine. Wine made from high-yielding vines tend to produce wines with light color, high acidity, and less alcohol, which are likely to oxidize ("brown") prematurely due to a lower concentration of tannins and anthocyanins (anti-oxidants). Fully developed grapes are typically 19 mm long x 17 mm wide, with an average weight of 3 grams.
  Soils with low fertility are ideal and help control some of the vigor of the vine. Planting vines in high densities in order to curb vigor may have the adverse effect of increasing foliage and limiting the amount of direct sunlight that can reach the ripening grapes. Advances in understanding the quality and characteristics of the different clones of Sangiovese has led to the identification and propagation of superior clones. While high-yielding clones have been favored in the past, more attention is being paid to matching the clone to the vineyard site and controlling the vine's vigor.
