The Marzadro Grappas are distinguished for their difference in taste and aroma, all while representing finesse and personality, as common denominators of high quality products, obtained by the pomace of local classical vineyards. The Grappa is carefully analysed by the Istituto Tutela Grappa del Trentino, a competent official body guaranteeing the quality of the product, that has been created in 1968 in the Province of Trento with the goal to protect and promote real Trentino Grappa. The Institute is responsible for controlling the origin of the pomace and the production phases that guarantee the quality of the Grappa.
