Obviously you haven't worked one of my flights, somehow I always manage to finish the bottle when it is Krug. Concorde carries the '86 Clos des Mesnil but I've never been fortunate enough to catch it (and it is no longer available retail). The Concorde wine list is described here The selection is of outstanding quality and contains many small production wines. The range is surprising (one of the Krugs is triple the price of the other, for example), but the worst wine on the list is still outstanding and hardly cause for complaint. Sometimes the Concorde Room also serves interesting wines though most of the time it is the F list. It is the BA F wine list that is a bit lacking, but that is another topic! Concorde is outstanding and presuming they continue to serve from the published cellar, I do expect (and get) great champagne on Concorde.
