Notes from Strade Bianche:

"After a career in law, Sandro Ruffo left his profession to pursue his childhood passion of wine making. Sandro's philosophy is to farm and make wine the same way it has been done on this hill for millennium. Colle Petruccio farms 8 hectares of wine and olive trees. Located just outside of Grosseto in the Maremma region, the soils are known for being incredibly rocky which gives the grapes produced a unique strength and minerality." 

"Norcias is spontaneously fermented in stainless steel for 21 days with native
yeast and a small dose of SO2. After 8 months in stainless steel tanks, the wine
is bottled, where it ages another 6 months before bottling."
