Ancestral method, therefore naturally sparkling. This technique has been handed down to us by Tonio, the mustache, Cinzia's father, who by producing a little wine for him also made a sparkling wine. The ancestral method, a technique very similar to the pet nat, is the oldest system of making a sparkling wine in a natural bottle, there is a bottling of the wine at the crescent moon, with the addition of dried grape juice or natural residual sugar from the first fermentation that give the refermentation in the bottle. the result is a more persistent and lasting natural sparkling, not being filtered it keeps the bubbles longer. A pleasant and easy to drink wine at all times. Spontaneous fermentation.
