The 'vin col fondo' is a naturally re-fermented white sparkling wine made with 100% Glera fruit and its must. After a maturation in vats, it is then bottled, and thanks to specific temperature control (15-18°C), the yeast ferments the residual sugars, saturating the wine into bubbles. After about about 60 days, the yeast settles at the bottom of the bottle leaving that unmistakable and unique natural preservative that leads to the wine’s characteristic aroma, texture, and flavor.
