Gancia operates in Asti, in the heart of Piemonte's sparkling wine country. The winery focuses on Alta Langa, the region's prestigious designation for traditional-method sparkling wines made from Pinot Noir and Chardonnay. Its flagship releases—Cuvée 36 Mesi Alta Langa Rosé, Cuvée 36 Mesi Alta Langa Brut, and Cuvée 60 Mesi Alta Langa Brut Riserva—demonstrate the house's commitment to extended aging on the lees. These wines have drawn assessment from Wine Enthusiast, Wine Spectator, Decanter, and Falstaff. The extended maturation protocols, particularly the 60-month aging of the Riserva, reflect the technical demands of Alta Langa production, where time and precision shape the final character of the wine.
