Ronco Matto - 2021 - Alessandra Bera

100% Barbera cuvée from 30-year-old vines grown organically and planted on a 0.3 hectare plot on limestone soils. Manual harvest, 10 days of maceration and start of spontaneous fermentation, pressing, a wine that did not "finish its sugars", that is to say that the alcoholic fermentation was not finished, bottled in June 2022 with 10 grams / liter of residual sugars, the effervescence is therefore due to this end of fermentation in the bottle. Not fined, not filtered, without added sulphur.
