What’s Really in your Beer?
The year is 1487 and you find yourself in the German Empire. You happen across a brewer and ask him what is in his beer. His answer: “malt, water, and hops.” Of course we now know that yeast is a critical fourth ingredient but in 1487, before the microscope, fermentation was the stuff of magical pixies and fairy dust. Back then the law known as the Reinheitsgebot dictated that beer only include malt, water, and hops.
