Is G.H. Mumm the same as Mumm Napa?

No. They share a historical origin (G.H. Mumm founded the Napa operation in 1979), but G.H. Mumm is the original French Champagne house based in Reims and still Pernod Ricard-owned, while Mumm Napa is a separate California sparkling wine producer under different ownership today.

G.H. Mumm Champagne — RSRV Blanc de Blancs Allocations

Founded in 1827 in Reims by German-born brothers Jacobus, Gottlieb, and Philipp Mumm, G.H. Mumm’s globally recognized red-sash "Cordon Rouge" label dates to 1875, created as a tribute to France’s Légion d’Honneur. Its Blanc de Blancs cuvée — now sold as RSRV Blanc de Blancs — traces back to 1882 and is sourced entirely from Chardonnay grown in Cramant, a Grand Cru village in the Côte des Blancs. G.H. Mumm remains a French Champagne house owned by Pernod Ricard, and should never be conflated with Mumm Napa.
