Today is the birthday of mathematician August Ferdinand Möbius, for whom several mathematical items are named, although the most famous is certainly the Möbius Strip. Although the Möbius Strip was discovered by two different mathematicians around the same year, 1858, it bears his name and not fellow German colleague Johann Benedict Listing.

A Möbius Strip “is a surface with only one side and only one boundary,” so that it looks like it turns in on itself, but if you could walk around on top of one, you’d never come to the end. “The Möbius strip has the mathematical property of being non-orientable. It can be realized as a ruled surface.”

I recalled seeing a famous beer label using a Möbius Strip, and a quick search revealed the one I was thinking of was Arizona Brewing’s flagship beer “A-1,” which used a multi-colored version.

Beer History has a good article about the brewery, A-1: The Western Way to Say Welcome
by Ed Sipos. The original A-1 label had an eagle on it, but by the 1950s Anheuser-Busch, which was spreading their tentacles nationally, decided to sue Arizona Brewing claiming the eagle on their label was too close to their own, and Arizona couldn’t afford to defend the lawsuit, and decided instead to simply change the label.

A can of A-1 from 1965-66.

And not too long ago, Tuscon-based Nimbus Brewery introduced a new version of A-1 Beer, though I’m not sure if it’s still being brewed.

Apparently there’s also a Mobius Infused Lager that looks like a gimmicky contract beer. It appears to be a generic lager “infused with taurine, ginseng, and caffeine.” Ugh, does that sound like a bad idea.
