Ca' dei Zago Prosecco
Founded in 1924, Azienda Agricola Ca’ dei Zago maintains 6 hectares of vineyards in Valdobbiadene in the province of Veneto. Christian Zago returns to the traditions of his grandfather to make this unique Col Fondo (on the sediment) Prosecco, which finishes its fermentation in the bottle under crown cap. This results in a Prosecco that is slightly cloudy with the sediment still in the bottle, a characteristic commonly found in Prosecco until the 1970s when pressurized tanks were introduced. There have never been any herbicides or pesticides used in the vines, which are all terraced on steep hills characteristic of the area, making machine harvesting impossible. Ca' dei Zago has been practicing biodynamic since 2010.
Vinification Method: The grapes are harvested and selected by hand then pressed, using the delicate force of gravity. Grapes never pass through pumps. After a smooth pressing, the must rests and decants for 24 hours. At the end of the second day the must is racked off and fermentation begins in Concrete tanks, lasting about 10-20 days, depending on the year. The wine is poured and sulfer is added, to avoid oxidation. For the whole winter season the wine rests and is decanted in stainless steel tanks with periodical remuage, in order to keep it homogeneous and to let the yeasts work. The cellars are outside so the exposition of the wine to the winter cold in addition to the contact with the lees produces the natural tartaric and protein stability of Glera wine. When the wine is around 1% short of finishing fermentation, it is transferred to bottle, after a very light filtering, to finish its fermentation there.
