More than half the beer brands out there are Anheuser Busch. 
A six-pack of Stella will sit in my fridge for months. But I'm not giving it up.
It's really pretty painless for me. In the big brands I would fall firmly in the Molson/Coors camp... Miller Genuine Draft and Miller Lite being most likely my whole life long... And I've had my share of Coors and Coors Light...
But at any real venue I might attend - Really, any of them, from rodeos to hot rod shows, From mud bogs to round and quarter mile tracks... All of em, everywhere, Bud Light banners reign. So yeah, I've drank my share of Butt Light, and then some.
That ubiquity is the thing that interests me most - What will those venues look like next year... Who can pick up the slack on all that? That's a whole lotta weight...
Already, as a readily recognized currency in beer fridges everywhere, I think they have fallen. I don't think I would show up at a shop after hours with a brown bag full of Transheiser products of any kind. Seriously - I wonder what will be the accepted currency now? Probably Coors Light around here.
