Reviews:

Disgorged in March 2024 with four grams per liter dosage, based on the 2018 vintage (50%) and complemented by a perpetual reserve component that dates back to 1988, the NV Brut Blanc de Blancs Grand Cru Réserve Oubliée goes through partial malolactic fermentation (as the rest of Péters wines) and is matured for about 18 months in a variety of vessels: large wooden casks, stainless steel tanks and concrete (roughly one-third each) before aging under cork in the bottle. Péters observes, and the wine confirms, that long aging on the lees contributes to an aromatic range of complexity that evokes associations of maturation in barrels. Opening in the glass to reveal notes of baked bread, toasted nuts, vanilla pod and dried fruit, it is harmonious and enveloping, laden with vibrant acidity and marked by lip-puckering salinity. It’s a perfect blanc de blancs for enjoying now, while laying down Les Chétillons in the cellar.  Wine Advocate - 93

Drawn from a perpetual cuvée of reserve wines used for the nonvintage blanc de blancs. Containing wines dating back to 1988. Here the base wine is aged an extra year in tank before tirage to create a mature, but not oxidative Champagne. Aged under cork.
