Baderbräu is a Pilsner made with Czech and German Noble hops, a private strain of European lager yeast, and malts from the USA.
[4] Later in 1990, in an attempt to increase sales, the Pavichevich Brewing Company started making medical claims about Baderbräu, which were soon dropped after an investigation by the FDA.
[6] An investment company called Prairie Associates acquired the Baderbräu trademark and formula then promptly sold this intellectual property to Goose Island for an undisclosed sum purported to be more than $100,000 US.
In 2010, entrepreneur Rob Sama registered the Baderbräu trademark and URL, sourced the original recipe (including its proprietary yeast strain), and restarted the company.
[8][9] In 2014, Sama leased a vacant warehouse on Chicago's South Side and began renovations to convert it to a new brewery.
