Light starts decay even in pure beer. Dark glass gives protection against light. Schlitz is bottled in a brown bottle to protect its purity from the brewery to your glass. In the Schlitz Brewery, some say, protection against impurity is carried to an absurd extreme. We don't think so. We have adopted every idea, every invention to attain and preserve purity. We scald every tub, keg and barrel—every pipe and pump—every time we use it. We wash every bottle four times by machinery. Even the air in which the beer is cooled is filtered. It is aged for months in glass enameled tanks. It can not cause biliousness. It will not ferment in your stomach. If you knew what we know about beer, you would say, "Schlitz—Schlitz in Brown Bottles."
