Sangiovese: Italy’s Most Planted Grape and Its Many Names

By the This Day in Wine History Editorial Team · ✓ Researched, fact-checked & verified · July 2026 · 7 min read

Sangiovese is the grape behind almost every great Tuscan red, from Chianti to Brunello. It is also Italy’s most planted variety, and it hides in plain sight under a dozen different names.

If one grape defines Italian red wine, this is it. Sangiovese covers more Italian vineyard than any other variety, yet most drinkers have met it without knowing, because it so often goes by a local alias.¹ (For the wider story, see our history of Italian wine.)

Blood of Jupiter

The name itself carries a legend. Sangiovese is usually traced to the Latin sanguis Jovis, the blood of Jupiter, a phrase folklore credits to monks in Romagna.¹ Wine historians treat that story with caution, since the etymology is hard to prove, but it has stuck for a reason: it suits a grape this old and this central to Italian life.

One grape, many names

Sangiovese’s real signature is its shape-shifting. It has mutated into a remarkable range of forms — over 100 registered clones plus countless local biotypes, and across central Italy the best of them go by local names.² In Montalcino it is Brunello; in Montepulciano, Prugnolo Gentile; in the coastal Maremma, Morellino; and across the water in Corsica, Nielluccio. Same grape, four identities.²

The same variety, renamed by each region that made it famous.

The backbone of Tuscany

Those names map onto Italy’s most storied wines. Sangiovese is the required heart of Chianti (at least 70–80% of the blend), the sole grape of Brunello di Montalcino (100%), and the base of Vino Nobile di Montepulciano.²³ It also runs through many of the Super Tuscans. Prized for high acidity, firm tannins and long life, it is a grape that rewards patience and reflects its site closely, which is why the same variety tastes so different from one hillside to the next.³
