Gaja’s 2021 Sperss is a Barolo DOCG sourced from Serralunga d’Alba, a zone known for producing Nebbiolo with structure and longevity. The fruit comes from the Marenca and Rivette sites in Serralunga; Kerin O’Keefe notes it explicitly as “from the Marenca and Rivette sites in Serralunga.” Made from 100% Nebbiolo and around 14% alcohol, Sperss is built in a serious, cellar-worthy style that multiple critics suggest will reward patience.

The top review comes from Jeb Dunnuck, who awards a perfect **100 points**, calling it “a beguiling matched balance of power and finesse,” “seamless from start to finish,” and “harmonious and resonating… over the next several decades.” That long-horizon message is echoed elsewhere. Wine Spectator (97 points) says “everything is in the right place, but this just needs time,” recommending it “Best from 2029 through 2050,” and adds an availability detail: “400 cases imported.”

Aromatically and on the palate, the notes span bright red fruit to darker, iron-tinged Serralunga depth. James Suckling (97) describes an “austere, restrained wine” with “graphite, red currants, strawberries, red cherries and blood oranges,” finishing “austere… in a positive way,” and advises “Best after 2026.” O’Keefe (99) emphasizes both detail and drive, citing “succulent raspberry, star anise, camphor and forest floor,” with “firm but refined tannins” and “fresh acidity” that supports “energy and longevity.”

Robert Parker’s Wine Advocate rates it **98+**, highlighting a “distinctive ferrous note of rusty nail or soft earth” around “dark fruit,” concluding the wine is “exceptionally balanced and beautiful,” finishing “decidedly salty and stony.” Vinous (97) frames it as a “huge, dense wine” with “black fruit, graphite, scorched earth, tobacco and incense,” advising readers to “plan on being patient.”
