The family vines were leased to Faiveley in 1950, prior to that (and starting in 1878) the family bottled some of the production for their family cellar. Sometimes wine was also sold, in which case it wore the label Château de Chambolle-Musigny From 1978 until 1984, the vines were returned to the family from their long lease to Faiveley (the Nuits Clos de la Marechale stayed longer with Faiveley, returning 01-Nov-2003). Winemaking was done in Chambolle by a ‘regisseur’ who just happened to be Bruno Clair. Withe the exception of the 1984s, all of the wine produced by Clair was sold in bulk to the négoce – the 1984s were still to be bottled when Frederic returned to the Château, and were the first to wear the Mugnier label. 1985 was the first vintage actually made by Mugnier.
