The Pacenti estate was established in 1970, with the purchase of the property north of Montalcino (Pelagrilli) by Siro, who then proceeded to plant some important vineyards, which are still there today, in the fresh, clay soils of the land overlooking Siena. In 1988, management passed into the hands of Giancarlo. This was the year of the harvest in which Rosso and Brunello di Montalcino Siro Pacenti were bottled for the first time.

At the beginning of the Nineties, the estate expanded to include land south of Montalcino (Piancornello).

Here, in soils rich in minerals, at the end of the Sixties Giancarlo’s maternal grandfather had planted five hectares of vineyard which were to prove particularly important in determining the characteristics of Siro Pacenti wines. This is now where the Sangiovese rootings used in the estate’s new plantations are reproduced. The Nineties were also marked by the start of the partnership with the University of Bordeaux and the first experiments on phenolic maturity applied to Sangiovese (Yves Glories). The new cellar was built between 2001 and 2004, combining technology and experience with respect for the grapes and the land.
