When I was a teenager, I worked somewhere that had a huge Budweiser sign with that phrase on it and I always laughed about it. At the time I don't think I had ever drank beer before, but I knew that it had to be pure nonsense, if for no other reason than judging from the price of a six-pack of Budweiser compared to the price of a single bottle of some Belgian Abbey ale or whatever. I don't think craft beers had started yet back then (or if they had, they were just getting started).
I never considered the slick possibility that they were saying "We know of no other brewery that makes as much beer as we do, and thus we know of no other brewery that spends as much total money as we do across all of our factories in the world."
Because that wouldn't be impressive at all. That would just be deceptive and pathetic. Obviously anyone reading the can isn't going to interpret that way. They're going to think it means "we don't know of another beer where each can or bottle costs as much to make."
