Professional Craft Beer Experience for Bar Nunn Residents
Built for the People Who Build Wyoming
If you're a Bar Nunn resident looking for a craft brewery that understands the kind of community you live in, the answer is just a short drive away in Casper. Bar Nunn is one of Wyoming's most family-forward towns - a predominantly homeowner community that runs young, blue-collar, and proud of it. Nearly half of all households have children under 18 at home, and the workforce here leans heavily toward the trades, construction, and hands-on professions that keep the region running. After a day like that, what you pour in the glass matters, and it should come from somewhere that gets that.
Gruner Brothers Brewing has built something in Casper that Bar Nunn residents have made their own. Housed inside the historic old Petroleum Club building with views of Casper Mountain, our taproom is the opposite of pretentious. It's a place built by Wyoming brothers who understand work ethic, community, and what it means to make something truly worth being proud of. From the brewing process to the welcome you get at the door, everything here is done with intention and without shortcuts.
Craft Beer Worth the Drive, Every Single Time
We offer a rotating lineup of handcrafted beers that suit every palate - light and crisp for those who want something easy to drink, or bold and layered for those who want to explore past the familiar. Our flagship beers have earned loyal followings across Natrona County, and seasonal releases keep things fresh for anyone who wants something new on every visit. The taproom runs Tuesday through Saturday, making it easy to plan a mid-week outing or a Saturday afternoon with people who earned a good time alongside you.
We also offer brewery tours for those who want to understand what goes into every glass, and private event spaces are available for Bar Nunn's milestone moments - birthdays, crew gatherings, retirements, and everything in between. Petro Pub serves food directly in the taproom, with flatbread pizzas, hand-held favorites, and shared plates that pair naturally with whatever you've got in hand.
When you're ready to find the craft brewery that Bar Nunn families and workers keep recommending to each other, come on over to Casper and let us show you what Wyoming beer is supposed to taste like.
