  Title: Pipeworks Brewing
  Passage: Pipeworks Brewing Company is a brewery in Chicago, Illinois.  The brewery opened in January 2012 by founders Beejay Oslon and Gerrit Lewis.  Pipeworks began their brewing different from other microbreweries in that they initially brewed their beers entirely as a series of 'one off' beers that were aimed specifically to the niche market of beer connoisseurs.  The brewery's stated goal is to release a new beer every week.  This approach gave the brewery and its beers somewhat of a cult status among beer enthusiasts, with its offerings selling out relatively quickly.  After seeing significant growth, both in output brand and identity, Pipeworks has since augmented their one-off beers with several of its 'core' beers in 16 ounce can 4-Packs now regularly available widley throughout the Chicago area.
