Last week, we posted about the obscure hieroglyphics scrawled on the bottom of each beer bottle, marking its expiration date for shopkeepers who know the code but hiding it from consumers looking for the freshest pint possible. Even when we posted it, we were a bit confused about the story: doesn’t some beer actually have a legible expiration date printed on the label? And that article was definitely the first time we’d ever heard that all beer had a clearly defined shelf-life, equal to the shelf-life of all other brews.
