This category is not certified, but it refers to wines with low intervention and only to the vinification process after the grapes are ripe, not the way the grapes are grown and harvested.
Natural wines are made in large percentage from grapes that are also grown organically or biodynamically. The process of making natural wine usually does not require intervention: the grapes are harvested and destemmed by hand, the must is not subjected to pumping, there is no mechanical separation of the must from the pomace and, finally, nothing artificial is introduced into the pomace. tanks (or amphoras, or concrete eggs). There are no rectifications in the form of added acid or sugar, there are no enzymes, and it is fermented only with autochthonous yeast that is found in the skin of the grape, which is known as “spontaneous fermentation”.
Natural wines are also usually produced unfiltered, which will normally give them less clarity and may result in a little sediment in each bottle.
Generally do not have added sulfites, though there are naturally occurring sulfites in wine production, which can help stability.
