Sparkling wine production with French grape varieties was established here around 1850 by Marchese Leopoldo Incisa, whose grandson Mario Incisa della Rochetta (1899-1983) created the famous Sassicaia in Tuscany. The sparkling wine is made from at least 90% Pinot Nero(Pinot Noir) and/or Chardonnay, and a maximum of 10% of other authorised varieties. It must be produced according to the Metodo classico(bottle fermentation) with at least 30 months of yeast ageing (36 months for the Riserva). There are four types of wine: Spumante, Spumante Rosato (or Rosa or Rosé), Spumante Riserva and Spumante Rosato Riserva (or Rosa or Rosé).
