(Portland, OR)  --  One of the founding fathers of Oregon's craft beer industry is retiring.  Art Larrance is selling Cascade Brewing to a group of brewery and taproom owners.  Cascade is known for specializing in sour beers but also offers a wide range of ales and lagers.  The deal is a phased transition and Larrance will remain in an advisory position.  The Cascade Brewing Barrel House, Blending House and Lodge at Cascade Brewing will all remain open.
