Cascade Brewing has been a pioneer in the 'Sour Beer' renaissance since 2006 and is the proud innovator of 'Northwest Sour Ale'. Our distinctive sour beer blends contain fruit, barrel-aged ales. These beers offer a complex array of flavors derived from the acid, the fruit and the residual flavors found in the barrels where they age. The resulting beer offers a complex range of flavors and aromas. Cascade Brewing's sour beer is brewed and blended in Portland, Oregon.
