No no. It is not a sour. I haven't had it, but I can tell by the description alone that it is just a dark strong of sorts. If you're letting the name Grand Cru lead you to believe that it might be sour, that's just not the case.
The Grand Cru is just a classification more than a style. It is supposed to be the premiere product of the brewery. The term originated in wineries, and the Belgian beer producers picked it up first. Typically a dark strong or a quad in variety, but it can be all over the map. Hoegaarden does an 8% wit that they call their Grand Cru.
