Wednesday’s ad is for Schlitz from 1912, and is touting brown bottles as the best package for beer. I don’t imagine UV light was as well understood a century ago, but Schlitz assures us that even then “chemists of this country as well have repeatedly warned against the possible dangers to purity following the use of light glass bottles.” And I love this gem. “Dark bottles only are used for beer in Germany and England.” Many? Undoubtedly. Most? Probably. Every brewery? Hmm, I’m sure someone can speak to the veracity of that claim, but I tend to think absolute claims are a bad idea. You can find an exception to almost anything. And I especially love their final words, urging people to choose Schlitz because they know best. “If you knew what we know about beer, you would say ‘Schlitz—Schlitz in Brown Bottles.'”
