The Solera method is an aging system that allows the grappa to merge different years in a harmonious blend as the time goes by. The new vintage is introduced in the barriques located on the highest row in the aging cellar, while the Grappa to be bottled is taken from the row close to the soil (solera). The solera row is never emptied completely, but just a part of it, which will be replaced by an equal amount of Grappa coming from the second row, which will be consequently fulfilled by the third row and so on, with a series of successive passages. This way on the lowest row, a blend of older and older vintages is obtained.
