To produce the Asti Spumante DOCG San Silvestro soft pressing of the grapes was made; slow fermentation in sealed stainless steel tanks at a controlled temperature. This lasts until the balance between alcohol (7%) and the residual sugars (3-5%) reach the correct level. The Asti Spumante DOCG San Silvestro is made sparkling following the Charmat method.
San Silvestro is located in the territory of the Commune of Novello. The grapes are mostly grown in the Langhe and from vineyards found in the Roero and the Monferrato regions. San Silvestro represents the continuation of a project begun by Giovanni Sartirano which has been passed down through four generations. Today it is run by cousins Paolo and Guido Sartirano and San Silvestro has gradually expanded beyond the local market and their wines can be found around the world.
