SUM converted a former produce warehouse into Cascade Brewing's new 7,000 sf facility at 935 SE Belmont in Portland. Much of the building - 5,000 sf, in fact - is devoted as a warehouse, either for barrel aging or bottle conditioning for the brewer's distinctive ales. The rest of the space features a small pub with seating for 80 and a deck for outdoor tables. With room for 200 wooden casks the 2500-sf barrel room is specially designed to keep the sours at a proper temperature for aging, specifically the cultivation of bacteria that give these brews their distinctive tang. Barkeeps pull pints for weekly tastings from two wooden barrels that protrude from specially designed openings in the pub's back wall. These holes open to the facility's barrel room, literally connecting the public space with the brewery's mother lode. The entry facade incorporates large sections of glass storefront, new signage and bike parking. Perhaps the most significant- and dramatic- change to the once dilapidated facade are the restored window openings.
