A winemaker dedicates his life to producing family wines, as the years go by he decides he needs to make new innovations to finally expand his business. For this, he decides to compare different wines that have gone through different production processes, within that he obtained 32 different vintages for evaluation. As a result, it was decided to summon five specialized sommeliers to validate the wines. The winemaker, thinking about this, five factors that differ for the final result of the harvest. Among these concepts, the harvest factors, type of grape, fermentation temperature, type of fermentation and time for wine ripening stand out. In order to simplify the results and reduce the number of discontinuous experiments, the winemaker defined that only two variations would be made for each item. Among these variations, we would have harvests made before the grape ripening and after the grape ripening; Varied wines made from grapes of the Carbenet Sauvignon and Tannat types, Fermentations made in Stainless Steel or oak barrels; Malolactic fermentation temperatures ranging between 12C and 18C; And the maturation varies between two and ten years of canning. Another key point of the experiment is the tasting by professional Sommeliers (Y columns). The winery invited 5 Sommeliers who experimented with 32 companies that resulted in different wines and gave a rating.
