This wine has garnered praise from several professional reviewers. Chuck Hayward of JJ Buckley rated it a stellar 93 points, highlighting its "pale straw" color and "steady bead." Hayward notes that while the nose is relatively subdued with a "barest hint of fresh bread," the palate is quite the opposite, offering an "explosive presence of firm citrus-laced fruit." He further describes the finish as "crisp," with "a kernel of sweet lemon candy flavors" providing a solid foundation.

Wine Spectator awarded the wine 91 points, emphasizing its "rich juicy notes of glazed apple, golden raisin, ground white pepper, and ginger." The review also mentions elements of "candied lemon zest and brioche," contributing to a "vibrant" profile. According to Wine Spectator, this Champagne is "harmonious and finely textured," with a "light toasty finish." They suggest enjoying this wine now through 2016, noting that 250 cases were imported.

Vinous reviewer Anne Krebiehl MW gave the wine a score of 92 points, offering a detailed breakdown of its composition. The NV Extra Brut Blanc de Blancs is primarily based on the 2018 vintage (65%), supplemented by 30% from 2017 and 5% from 2019, sourced from Chouilly, Cuis, and Epernay. Krebiehl highlights an "immediate hit of saltiness on the nose," indicating a focus on the soil rather than fruit. She commends the "fine mousse and bright slenderness," which contribute to its "elegance and verve." The mid-palate is described as having "salty depth and a touch of blond baguette crust," making it a quintessential Blanc de Blancs with "freshness, verve, and elegance." The dosage is noted at 3 grams per liter, and it’s recommended as an aperitif or paired with oysters.

In summary, the NV Diebolt-Vallois Brut Blanc de Blancs is a well-regarded Champagne that emphasizes structure, elegance, and a harmonious blend of flavors. Whether enjoyed on its own or paired with seafood, this wine promises a refined and crisp experience.
