Will the real second wine please stand up?

[TheEngineer]

Okay...rather confused now...I know that Sarget Gruaud Larose is the second wine of Chat. Gruaud Larose...tonight I picked up a case of La Roseraio de Gruaud......both are supposedly second wines...

Apparently there is also a Chevalier de Gruaud Larose which is a version 1.5...somewhere between version 1 and the two seconds......

I read about the potential that the Benjamin may be a France only version of PC, and the US gets the other label.....
