Cortese grapes are grown on the hills near Gavi, not far from the Ligurian Sea, producing this Gavi D.O.C.G. Cortese is a white grape variety grown in the Alessandria area, especially on the hillsides surrounding the town of Gavi. This variety is not robust and requires good climatic conditions to ripen properly. In the Alessandria area, it has found the essential conditions to produce excellent results. The soils are rich in marl and fossils, providing a unique terroir for this unique wine.

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 has been passed down through four generations, and 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 recognised.
