The immediacy of processing, from vineyard to winery in a very short time, ensures quality. In two large open oak vats, whole clusters (whole grape) and destemmed grapes are started for alcoholic fermentation. After a brief cold maceration of 4-5 days, fermentation begins spontaneously from the delicate balance of sugars and microorganisms present on the skins and in the winemaking environment, without the addition of pre-packaged yeasts, in a totally natural process.
