Champagne Philipponnat Grand Blanc Extra Brut

EDITORIAL NOTE FOR WINE-NOW TEAM: The brand library provided covers Philipponnat Royal Reserve NV Brut — a Pinot Noir-dominant non-vintage blend. The product listed (SKU WSP2548DJ) is named Grand Blanc Extra Brut 2015, a vintage Blanc de Blancs-style cuvée at a distinct price point (฿5,900). No validated facts about this specific cuvée — its grape composition, dosage, vineyard source, winemaking parameters, or vintage notes — appear in the brand library supplied. Per the factual discipline rules of this brief, fabricating technical parameters, blend composition, or tasting notes for an unlisted cuvée would violate the content standard required for a ฿9k–฿65k-tier retailer. Action required: Please supply a brand library entry specific to the Grand Blanc cuvée (vineyard sourcing, Chardonnay village sources, dosage g/L, lees aging duration, oak use, disgorgement date, and any critic scores) so a curation-grade description can be written to the required standard.
