“Osso San Grato is unquestionably one of the great wines of the world.” – Antonio Galloni, Vinous

"Antoniolo remains a reference point for Gattinara and Alto Piemonte. As always, the Castelle and San Francesco have a touch of French oak sheen that renders the wines very easy to enjoy on the young side. The Osso San Grato is aged entirely in cask and, therefore, has more classic lines. It remains one of the benchmark wines of Gattinara and Alto Piemonte. As good as the single-vineyard bottlings are, readers should not pass up the straight Gattinara, which is now also released as a Riserva. It’s a fine introduction to this stellar range." – Vinous

A legendary cru and the crown jewel of Antoniolo’s holdings, Osso San Grato is 100% Nebbiolo (old local clones) from a five-hectare monopole that towers above the town of Gattinara. Planted between 1940 and 1950, the vines rise to 500 meters above sea level on pale, dusty topsoils of clay and mineral sand layered over igneous rock. It is one of the world’s great Nebbiolo vineyards and produces a wine of striking purity and longevity — taut, mineral, and deeply expressive of its volcanic terrain. It stands as the traditional, age-worthy counterpoint to San Francesco’s supple modernity, together defining both Antoniolo, and Gattinara itself.

Fermentation is spontaneous, with an 18-day maceration in concrete vats and no temperature control. The wine then matures for 36 months in a combination of large Slavonian and French oak casks (25–35HL), followed by a further 12 months of refinement in bottle.

“The 2020 Gattinara Riserva Osso San Grato is immediately distinguished by its creamy, layered personality. Dried flowers, blood orange, spice and sweet floral overtones build over time. Elegant and refined, Osso San Grato is sublime in 2020. This is an unusually open-knit vintage for Antoniolo's flagship wine.” 94 Points - Antonio Galloni
