The estate vineyard at Piancornello was bought by the Pieri Family in 1950. The fruit was sold to other Montalcino producers until they began making there own wine starting with the 1990 vintage. Silvana Pieri owns the estate and her son Claudio Monaci is the winemaker.
Piancornello takes its name from the hamlet just South of Montalcino where the winery is located. Because of the warm climate this is considered one of the finest areas of Brunello.
The vineyards are located on moderately sloped hills with rocky, volcanic soils and southern exposures. The clones at Piancornello were chosen carefully in order to have low yields and looser bunches. A modern winemaking facility has been built in front of the old cellar. The new facility is humidity controlled with ample provisions for the various barriques and traditional 30 hectolitre barrels employed by the winery.
