The wines tasted were from 2005 and 2008. The wines are divided in four categories; "grands vins", keeping wines; fruity wines; discoveries.
In the "grands vins" category, the top 10 are -
B. Baudry - Chinon La Croix Boissée 08
Joguet - Chinon Clos de le Dioterie 08
Alliet - Coteau du Noiré 08
Dom. Chevalerie (Caslot) - Bourgueil Busardière 08
Château de Coulaine - Chinon La Diablesse 08
Joguet - Chinon Clos du Chêne Vert 08
Alliet - Chinon Vieilles Vignes 08
Ch. de Coulaine - Chinon Les Picasses 08
C & P Breton - Bourgueil Les Perrières 05
Joguet - Chinon Varennes du Grand Clos 08
Surprises are the absence of Yannick Amirault (but he has three wines in the 11th to 20th tranche), the strong showing of Joguet and the appearance of Château de Coulaine (not previously on my radar screen; something to be remedied).
In the keeping wines category, Lamé Delisle Boucard's Bourgueil Prestige 05 comes top, but only with the same score (15.5/20) as the 30th wine in the "grands vins" category.
The fruity wines category (for immediate drinking
