Upright Brewing (address and info)
Top-rated brewery: The Commons Brewery
Another crowded field packed with breweries -- not a bad problem to have, mind you -- Oregon's pick for most underrated brewery could have been any number of breweries from any town across the state, which has its fair share of legends big and small. But our gut went with Upright, and not just because our gut was thirsty for its amazing table saisons, fantastic oyster stout (best served at the Upright-affiliated Grain & Gristle), and a session stout that redefines what the traditionally robust beer can be. The open-fermentation system produces fantastic-tasting room-exclusive sours, and lest you find yourself in need of something lighter, well, it also does pilsner proper. It does everything proper. Portland's beer nerds know all this. It's time for everyone else to catch up.
Pizza Boy Brewing Co. (address and info)
Top-rated brewery: Victory Brewing Co.
Bottles are extremely rare. Sorry. But Pizza Boy does deliver kegs to PA and NYC, so finding it isn't some sort of search for a greasy grail, which is fantastic, because, well, the beer is fantastic, especially the sours. To wit: the newest batch of Permasmile is about to be released, a white-wine barrel sour aged with peaches and apricots. The pizza shop it shares a space with (Al's of Hampden) has been there for 15+ years, but the brewery only got started in 2011, which is notable only because of how quickly it's ramped up, expanding three times in a few years. In addition to the sours, the Sunny Side Up imperial coffee stout, and the Hampden IPA are standouts. For visual proof of their greatness, a friend of Thrillist even made a beer doc that includes Pizza Boy's story.
