Like them or not, sour and aged beers are a Big Deal in Portland. Much of that is thanks to Cascade Brewing—a brewpub that almost single-handedly changed the landscape of the city's brewing scene with barrel-aged, fruit-infused blond ales and IPAs, all of which can be found at this busy, industrial brewpub, accompanied by tasty cheese plates and sandwiches.
