The Cortese is a white grape variety typical of the Piemonte area. It is grown on the Monferrato hills, in marl clay and sandy soils. It is not a very robust variety and requires good climatic conditions to ripen properly, but has found its place in the vineyard on these hillsides producing a fresh wine rich in minerality, expressing the terroir of the Monferrato hills. The wine takes its name from the beautiful Princess Adelasia, the bride of Aleramo, who was the first Marquis of Monferrato.

Established in 1871, San Silvestro has produced DOC and DOCG wines from its estate winery in the Commune of Novello in Piedmont. The traditional varieties are mostly grown in the Langhe and from vineyards in the Roero and the Monferrato regions. Founded by Giovanni Sartirano, San Silvestro and passed down through four generations today, it is run by cousins Paolo and Guido Sartirano. Following the family traditions and ethos, they hold the Equalitas certification for their sustainably cultivated vineyards and produce modern wines that express the Piedmont region's traditional varieties and distinctive terroir. Over the years, San Silvestro has gradually expanded beyond the local market, and their award-winning wines are internationally recognized.
