After a meticulous analysis of all the barrels where acidity and density data are recorded, the data will be used to make the necessary corrections to obtain a perfect product. This precision work is carried out respecting biodiversity, increasingly giving space to the principles of biodynamics. At the final sampling, before bottling, a visual test will be conducted with the flask and the palate of the master vinegar maker who will decide if the product has met all quality standards. Gubertini vinegar never compromises, even at the cost of not bottling a vintage if it does not fully respect the creative ideal.
