Well, not really - but there is some sort of speculation going on about that very possibility:

The ground-breaking study shows that the hippocampus, the part of the brain involved in memory, spatial tasks and many other functions, was more than 10 per cent smaller in those whose tipple was wine than in those who favoured beer. Researchers say that alcohol alone may not account for the differences because the beer and spirit drinkers had greater lifetime consumption of alcohol; in the case of beer drinkers some had consumed twice as much alcohol as the wine lovers. One theory is that there may be something in beer that partially protects the brain from the damage caused by wine.

Something? Something!?! You would think that "researchers" from from Germany's Göttingen University would be coming up with something better than, you know...something. Who knows? Maybe it's the puny hippocampus-ed among us who are driven to wine though some sort of of hypo-hippocampus twist of fate. They haven't got the hippocampus to handle a good brew. Nah, that can't be it - it's gotta be the malty goodness. Or maybe balance. That must be it: beer has a good deal of balance and that is good for the brain. If I was an egghead in a white lab coat that's what I'd say. Balance is good for the brain.
