The 2017 Gattinara Riserva Osso San Grato is an especially potent, savory wine in 2017. In most vintages, Osso San Grato is the most refined wine at Antoniolo, but that is not at all the case in 2017. Strong savory and earthy notes infuse the bouquet with quite a bit of character. Bold and powerful on the palate, with forbidding tannins, the 2017 is a wine to bury in the deepest corner of the cellar
