The hand picked harvest of the glera grape in the Refrontolo hills of begins between the end of August and the beginning of September when the grapes are ripe, i.e. the fruit has reached the correct maturation. In order to establish the ripeness index of the grapes, calculations are used, such as, the relationship between sugar and total acidity. When measurements remain constant over a few days, the harvest can begin. Our vineyards adopt hand picked harvest processes because they want to obtain a superior quality of wine that starts from grapes in perfect condition, mature to the right point and healthy.
Many winemakers, especially in the huge vineyards of the plains, adopt mechanical harvesting by using of the "grape harvesting machine" which speeds up the collection time but leads to a loss of quality right from the start given the presence of foreign materials such as pieces of bark, leaves and shoots or insects such as flies, etc., Moreover, the fact that many grapes are broken, the pulp which is exposed to the air is open to oxidation, which creates further qualitative loss.
In the Refrontolo hills it’s customary after the harvest, in the evening, to prepare long tables where all the harvesters eat, talk, relax and drink together.
