The white wine is mainly obtained from the fermentation of white grape musts, to a lesser extent there are also white made from red grape varieties called "Blanc de Noirs" in these cases there will normally be a discoloration of the must. The important stages in vinification of white include skid and treading the grapes after the harvest. The grapes will be pressed to obtain must and be able to carry out the fermentation. Although the most common whites wines are young and have not undergone aging, aging in oak barrels or tanks on the production of these wines is a common occurrence.
