Pabst was founded in Milwaukee in 1844 by Jacob Best and later sold to beer tycoon Paul Kalmanovitz. The company was later left in a charitable foundation after Kalmanovitz's death until a judge declared that it had to be sold. Metropoulos, who works with his sons Daren and Evan, bought Pabst from Kalmanovitz Charitable Foundation in 2010 for $250 million. Pabst Brewing's portfolio includes such brands as Pabst Blue Ribbon, Lone Star, Rainier, Ballantine IPA, Schlitz, Old Style, Stroh's and Old Milwaukee. Metropoulos announced in March 2014 he was seeking a new owner for Pabst. The brewery was expected to fetch between $500 million and $1 billion, according to some estimates. In September 2014 Oasis Beverages, an international beer and beverage company founded by Eugene Kashper, said it had agreed to acquire Pabst Brewing Co.
