I enjoy Karben4's beer.
So much, that I came all the way over to the East Side to fill up a growler. The bartendress took a look at my growler and said "we can't fill this if it doesn't have a government warning label on it." I was totally confused. I've gotten this growler filled multiple times in multiple other places across Madison without any issue. She wouldn't fill it. She offered to sell me one of Karben4's growlers, but no-go on filling my own, which is a Portland Growler Co. growler. "Maybe you can go home and print off a label." That's it. Sayonara.
So now I'm home, and trying to find any real literature regarding these filling laws. The best I can figure is that they are completely misinterpreting the Alcohol and Tobacco Tax and Trade Bureau's (TTB's) laws, which state that closed sealed containers sold by the brewery need a federal warning label. It also clearly states, on their website that growlers brought in which are not prefilled are considered open glasses and do not require the label. "
So wise up guys. Stop refusing to sell people your beer. And, of course, if you can demonstrate information proving otherwise, I'm happy to remove this review.
