Tell me about Grand Cru. Just thirty minutes ago I was in a grocery store near work and noticed Grand Cru for the first time.
It's essentially Rodenbach, but blended with a higher percentage of their aged beer. It's 66% vs the 25% that's in their standard beer. It's more tart, more assertive. I like it, but if you were turned off by Duchesse, you might not be into it. They are somewhat similar, although I'm sure someone will chime in to disagree!
