FWIW...

I think Ayala is better than Lanson. Taittinger better still, agreed

Krug is where BA (F) need to be aiming - it is the best going NV (and some V) champagnes around.

Don't knock Pommery - their NV is nothing special but their Cuvee Louise is fantastic. This would be a great V fizz if BA decided to explore that avenue.

Sorry but Salon is not likely to appear due to volume needed and cost. And Cristal, I don't think so

However Ruinart sounds like an interesting idea for CW.

I do hope BA are watching
