Oh, I have had quite a lot of mature Malconsorts – and many really fine ones … old Clos Frantin (now Bichot) can be marvallous … 1985, 1982, 1979, 78, 76, 71 …
Also Grivelet (the former owner) made fine Malconsorts (1957, one of the best wines of my vintage … and 1962 and 64),
Another producer is/was (the late) André Cathiard, father of Sylvain, who first made M. en metayage (Cathiard-Moulinet), later purchased the parcel … 1990 is still great, 1979, 1978 …
Sylvain made great M. – and especially 1997 has been fully mature and fine … and 2000 is similar, 1999 will be extra when mature eventually. I´m not sure if his son Sebastian is still on the same level … vintages since 2011 are missing the „special something“ …
Moillard (-Grivot … also Thomas-Moillard) made very traditional ageworthy M., nothing for young drinking, but if you taste 1966, 1969, 1971, 1976 … mmmhhh … (if the bottle is in good condition).
This parcel has been sold to Dujac and Montille in 2005 … and please note that there has always been a part of Les Gaudichots in it (already at Moillard), and still is in Dujac … but all still too young for me.
I´ve not had many mature M. from Lamarche … and 1976 and 83 were good, but not great …
Hudelot-Noellat makes his M. in his usual elegant style, and it is always one of the best 1er crus (with Beaux-Monts and Suchots …)
Malconsorts was a favorite among negociants (I guess Moillard sold a lot, but maybe also Clos Frantin …) – and I´ve had fine bottles, e.g. by Vasseur (some relation to Moillard), Ladoux, Jaboulet-Vercherre and others … from the 60ies to 80ies …
Also Potel made fine M. (2002, 2003, 2005 …) … and Le Moine (2007, 2009 …)
The judgment is wanting on Dujac and Montille since all are too young, but I have been quite disapointed with Dujacs 2007 … simply too light …
At the moment there are 6 proprietors: Bichot, Montille, Dujac, Cathiard, Lamarche and Hudelot-Noellat.
