A few kilometers north of Castelnuovo dell’Abate, towards Montalcino, at elevations between 395 and 415 meters above sea level, with southern exposure, lie the two Pian Bossolino vineyards: Pian Bossolino Alto (1.3 hectares), situated between 415 and 408 meters, and Pian Bossolino Basso (1.9 hectares), between 408 and 395 meters. The soils are very stony (30–35% skeletal content), with a clay-loam texture and excellent drainage. The vines, approximately 15 years old, are trained using the spur cordon system.

This parcel includes two distinct vineyard blocks.The first lies approximately 500 meters south-east of Castelnuovo dell’Abate, at elevations between 305 and 335 meters above sea level, with a southern exposure overlooking the Orcia River valley. The second parcel, located about 50 meters to the west at lower elevations (270–280 meters), with a west-facing exposure, is currently being prepared for replanting. Soils are calcareous, well-drained, with a loamy texture and a significant presence of schistous galestro. The existing vines are approximately 15 years old and trained using the spur cordon system.
