In Canada at least, the beer you could get in 40oz bottles was generally pretty strong. For example, Colt 45 is 8%.

The hardest part of Edward Fourtyhands is that you’ve got to consume 80oz of strong malt liquor without peeing. Or... figuring out some way to unzip your pants...

Yeah lots of malts are up there, I suppose the game came about before the craft beer movement- many of these new craft beers are 9 to 13 and would never be sold in 40-form I suppose, so those are high ABV for a 32/40 I’m sure.
