What happens when you mix goats, craft beer, rock and roll, bean bags and all-terrain tricycles? You end up with Boulder Beer’s 5th annual Goatshed Revival, happening August 23 from 12 to 7 p.m.

The revival is Boulder Beer’s 29th anniversary celebration. Since 2004, Colorado’s first microbrewery has marked its birthday with an event that pays homage to its humble beginnings in 1979. Two CU professors were determined to brew beer, while their wives were equally determined that it wasn’t going to happen in their basements.

“So they found a farmer who was willing to let them try this business out in the goatshed,” says Dan Weitz, Boulder Beer’s director of marketing. “But it was such a novel idea, they didn’t build a new shed, they just had to work around the goats.”

Five years later Boulder Beer built its brewery at 2880 Wilderness Place. The original founders, Randolph “Stick” Ware and David Hummer, have since moved on, and there are no live goats in residence, but Boulder Beer’s crusade to save the world from mass-produced “yellow beer” continues.

You won’t find any live goats at the revival, either. Weitz says they’re too mean, and hard to control. These days, two stuffed goats named Stick and Hummer serve as company mascots and reminders of the early years.

What will you find? Live music throughout the day, from Riff Raff and Bull Mary, a beer garden and grill, guided brewery tours every half hour, and the chance to test your skills at the cornhole and trikelocross tournaments.

The cornhole tournament is essentially a bean-bag toss for adults, but with strict rules and guidelines. If you want a leg up on the competition, you can learn more about the sport at Playcornhole.org.

The trikelocross is patterned after Boulder’s Cyclocross, which Boulder Beer sponsors, and will feature participants maneuvering their all-terrain tricycles through an obstacle course. Both tournaments begin at noon, with championship rounds at five. Prizes include, naturally, a keg of beer.

Admission is free, and proceeds from beer sales benefit Community Food Share. Last year’s revival raised $5,000 for CFS.

“One of the things we do here at Boulder Beer is we are active in our community,” Weitz says.

“This is one of our opportunities to give back in a big way. We donate throughout the year to hundreds of charities in smaller amounts, but this is our major fundraiser of the year. We are a business but we have to be part of the community first. In the community you don’t stand alone; everybody supports each other.”

Along with offering Boulder Beer’s nine brews on tap, brewmaster David Zuckerman has formulated some limited edition draft brews specifically for the event.

Kjell Wygant, the winner of Boulder Beer’s homebrewing contest, will also be on hand to unveil his creation. Wygant, who lives in Parker, won the top prize with his version of a saison, a French lager.

“It’s very refreshing,” Weitz says, “and this will be the only place you can get it.”

Among the many brews Boulder Beer offers, Weitz doesn’t claim a favorite. “My favorite beer is whatever I’m drinking,” he says.

“Boulder Beer is unique – in that we don’t have a flagship beer, per se. Some breweries, 95 percent of what they make is one brand. Our biggest seller is Hazed and Infused, and it’s 32 percent of our sales. I think we’re fairly unique in that way.”

Boulder Beer also offers a distinctive environment for enjoying its brews.

“We have arguably the best patio in the city of Boulder,” Weitz says. “It’s one of Boulder’s best-kept secrets.”
