The Chalky Blanc de Blancs was aged for an astonishing 72 months on lees - or six years. The base wines of this initial NV release come from the "late-ripening, almost brutally brilliant year" (Lobenburg) 2013. Disgorgement was in 2021, with a dosage of 6g. The resulting wine is creamy, mineral and - you guessed it - chalky.
