Castel Grumello , owned by the De Piro family in the fourteenth century, is a twin fortress, made up of two separate structures, once joined by a wall overlooking the hill cultivated with Nebbiolo delle Alpi . Hence the name of this wine, the result of the assembly of grapes from the two estate vineyards located in the Grumello area . In years in which the tannins are not very accentuated and suggest a short refinement in large barrels, the Valtellina Superiore Grumello Rocca De Piro DOCG surprises with the speed with which it acquires drinkability. And when it makes its debut on the table, it always presents itself punctually: ready to drink, but also excellent to store in the cellar among the reserves.
