Marshall Brewing Co. (address and info)
Top-rated brewery: Prairie Artisan Ales
It's not an exaggeration to say there are more breweries in a few square blocks of Portland, OR than in the entire state of Oklahoma. But by golly are there some good breweries packed into the state -- Prairie obviously being one of them. A mere 10-minute drive from Tulsa's Prairie brewery is Marshall, which began brewing a few years earlier. Marshall isn't currently the main event in its own damn town, despite setting the table for breweries like Prairie and Dead Armadillo, which is a perfect recipe for being underrated. In addition to its popular 6.5% ABV Atlas IPA, Marshall brews the dry-hopped, 80-IBU El Cucuy black IPA (an underrated style if there ever was one), and the märzen Oktoberfest.
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.
Foolproof Brewing Co. (address and info)
Top-rated brewery: Proclamation Ale Company
Proclamation is the hot brewery of the moment and Grey Sail also has its rightful adherents, but it'd be a mistake to overlook Foolproof, which has made a name for itself after having to... change its name in the early going in 2012 (the original name, High Jinx, found itself in dispute with a certain magical brewery in Vermont). Now it's all about the beer, as it should be when you're brewing beer excellence like their Raincloud porter, of which they, in true New England fashion, offered a limited variant brewed with peanut butter & marshmallow fluff.
Freehouse Brewery (address and info)
Top-rated brewery: Westbrook Brewing Co.
South Carolina beer has a lot keeping it off the radar in general, what with the wealth of breweries that don’t bottle, and its glory-hog of a neighbor to the north. But that just means there's more room for discovery, and we definitely recommend discovering Freehouse, which, like the more famous Westbrook, specializes in Old World brews with a twist. That results in some bizarrely wonderful offerings such as the Mullet -- an India pale... coffee brown?! -- a 9% imperial farmhouse, and a wild-yeasted kiwi/peach sour that comes out of left field. If you’re looking for something predictable, well, you're not going to find it. That’s a very good thing for most of us.
Hay Camp Brewing Co. (address and info)
Top-rated brewery: Crow Peak Brewing Co.
We often tease South Dakota, but we also really love it, and a huge part of that love stems from the undiscovered breweries therein. And while Crow Peak has long been the favorite, that doesn't take away from the efforts of brewers across the state. But it's in the Crow Peak-adjacent Rapid City that Hay Camp is shelling out solid beers like the deceptively smooth Best Bitter, the booming Hopdlebar Maltstache double pale ale, and more. (You want beer-snobby? A Cascadian black ale's the closest you're gonna get, neckbeard.) This is no-nonsense beer brewed under the watchful eye of a gigantic stone carving of Teddy Roosevelt, for God’s sake. You don't want to disappoint the Bull Moose.
