Of the 12 specific plots in the Maison Mumm vineyard, equally distributed between Pinot Noir from the Montagne de Reims and Chardonnay from the Cote des Blancs, seven were selected for the unique blend of RSRV Lalou 2006 (Les Bionnes, Les Crupots, Les Briquettes, Les Perthes, Hannepes, Les Rochers, Les Houles).

These seven Grand Cru wines were previously pressed separately, then vinified one by one. In line with Maison Mumms uncompromising standards, a 10-year aging period and a dosage of 6 grams per liter fully reveal their complex and elegant aromas.
