Robert Parker's Wine Advocate, with Monica Larner as the reviewer, gives the wine 91 points. Larner emphasizes the "tonic freshness, zesty citrus, white peach, and crushed oyster shell" aromas of the 2017 Langhe Alteni di Brassica. She notes that the grapes were harvested early in the hot growing season to preserve the freshness and crunchiness of the fruit. Gaia Gaja, co-owner of the winery, mentioned that the fruit was highly concentrated, with clusters of "bonsai grapes," which contributed to the wine's concentrated aromas and surprisingly fresh acidity.

In summary, the 2017 Gaja Sauvignon Alteni di Brassica is a well-regarded Sauvignon Blanc that balances freshness and concentration. With scores ranging from 90 to 93 points, it is celebrated for its bright acidity, nuanced flavors, and potential for aging, making it a noteworthy addition to any wine enthusiast's collection.
