From Polaner Selections:

Stella di Campalto’s estate, originally known as Podere San Giuseppe, was founded in 1910. It fell into abandonment during WWII and had been in an a state of near ruin since that time. In 1992, her family purchased the delapitated estate and began to resuscitate the property. The estate is comprised of approximately thirteen and a half hectares in total, with five and a half currently committed under vine. The head of the family winery is the lovely Stella di Campalto, who has overseen the winemaking and viticulture since 1992. She has practiced certified organic farming here since 1996 and in 2002 began practicing biodynamic farming as well – becoming certified in 2005. The estate lies at the very southeast corner of the Montalcino zone, outside of Castelnuovo dell’Abate. Sourced from four different vineyards."
