A question about a vineyard?

[c53411]

Hi
I am taking a wine/food pairing class at the moment and our lecturer brought in a man from a distributor of German wines. This man asked us as a fun question (but I know it will appear on our quiz next tuesday!) about a vineyard called 'chateau Lafite Rocher' or at least that't what it sounded like (he wouldn't spell it for us). The question was "what one wine is kept in their cellars?
I would appreciate any answers or leads that i could follow up a net search

thanks
