For generations the Spagnol family has done nothing but earn their living as Prosecco grape growers. Starting in 1986 they began to bottle their own wines. The Spagnol family owns vineyard land in what is commonly accepted as the Grand Cru area of Valdobbiadene Doc Prosecco: a handful of impossibly steep hills situated between the villages of Vidor, Colbertaldo, Guia, Saccol and Cartizze.
No consulting winemakers, no cultured yeasts, no purchased grapes at Castlier; rather, 100% estate old vines tended with the traditional Pergola system, reproduced from massale cuttings and located in the most extreme, rocky, steep parcels located exclusively in the Valdobbiadene Grand Cru area. Estate vineyards are 25 to 50 year old, afford ideal growing conditions (south-south and south-east exposure), and push their roots straight into the cracks of giant white stones from the Piave river valley ['Sasso Bianco del Piave' terroir].
