The bunches, which have been selected and collected in baskets,are sorted. Thanks to some natural yeast, spontaneous fermentation takes place in wooden barrels. During fermentation one sole fulling process ( batonage) is carried out. Wine fermentation can last from 6 to 9 weeks, then wine is aged in wooden barrels for about 30/36 months. No oenological intervention is applied during the cellar phase, not even any SO2 is used.
