UPDATE: now with readers’ photos of Party Seven!
Beer has been a vital part of society for almost all of civilised history. 4000 years ago the Sumerians were brewing in honour of their gods; in medieval Europe beer represented something clean to drink when the purity of water was questionable; nowadays it’s used more as a social lubricant. And which discipline of natural philosophy
is responsible for this nectar of culture, health and prosperity?
Well of course I wouldn’t be writing about it if it weren’t chemistry. But therein lies the problem – who these days cracks open a can and thinks to themselves “thank goodness for the clever research chemist who invented a vinyl co-polymer/C-enamel coating for tin cans”? But chemists are the ones behind all these advances in canning technologies and the art of zymurgy (“chemistry of brewing and distilling”, dontcha know).
As we put out the call for surviving cans of “Party Seven”, a septa-pintal vessel taken to parties in the 60s and 70s containing (allegedly) decidedly ungourmet beer, I thought I’d look into the chemistry of beer cans – and would you believe it, the beer can’s 75th birthday is later this month. See the bottom of the post for more details on our Party Seven quest. (more…)
