Guinness actually does not have an aluminum beer bottle.
But I did come across this really neat design for an aluminum bottle for the venerable English beer by someone named Julien Muller. You can take a look at his work here.
I like the angular shape which is quite different from most aluminum beer bottle designs which are rounded. The design is part of a project by Muller called “Prism, Stripes & Diamond bottles”.
The malleability of aluminum would probably make this non-traditional design feasible. The Guinness “brand police” would probably not allow any bottle not to have their iconic Guinness logo. But theirs is a dark logo and would probably blend easily with Muller’s design.
It’s wonderful how aluminum bottles have become the new canvasses for today’s artists and designers.
