The NV Pierre Peters Réserve Oubliée Blanc de Blancs Grand Cru Brut is a standout Chardonnay from the esteemed Champagne region of France, particularly the Côte des Blancs. Known for its meticulous production process, the wine undergoes partial malolactic fermentation and is matured in a variety of vessels—including large wooden casks, stainless steel tanks, and concrete—before aging under cork in the bottle. This method contributes to its complex aromatic profile.

Robert Parker's Wine Advocate rates this wine at 93 points, highlighting its "harmonious and enveloping" nature with notes of "baked bread, toasted nuts, vanilla pod, and dried fruit." The wine's vibrant acidity and lip-puckering salinity make it ideal for immediate enjoyment, while also suggesting its potential for further aging.

Vinous, awarding it 92 points, describes the wine as "delicate and lifted," with a blend of citrus, mineral, and floral notes. The extra aging on lees and subsequent cork maturation add to its finesse. Antonio Galloni of Vinous notes the wine's fine touch and provides a dosage of 4 grams per liter, indicative of its balanced sweetness.

Jeb Dunnuck offers a stellar 95-point review, praising its "floral and fruity bouquet" and the depth contributed by its maturation in a combination of stainless steel, concrete tanks, and Stockinger barrels. He describes it as "medium to full-bodied" with a refined mousse and elegant finish, suggesting it will develop further complexity over time.

Decanter also awards it 95 points, lauding it as a "top-notch release" with flavors of sourdough toast, dried citrus, and clementine. The wine's energy and depth are highlighted, marking it as an under-the-radar gem with a beautifully settled mousse and fine tapering length.
