165 Breweries to Pour at Colorado Brewers Guild Collaboration Fest on April 4

The celebrated craft beer festival to showcase more than 120 beer collaborations at The Westin Westminster

DENVER, Colorado (Feb. 17, 2026) – Organized by the Colorado Brewers Guild and presented by On Tap Credit Union, Collaboration Fest is the original collaboration-focused craft beer festival that highlights the spirit of camaraderie and innovation that makes Colorado’s craft beer community truly distinctive.

More than 160 craft breweries will be pouring over 120 beer collaborations on April 4 from 2 to 6 p.m. at The Westin Westminster (10600 Westminster Blvd, Westminster, CO 80020). The full list of participating breweries can be viewed here.

“Collaboration Fest has earned its place among the nation’s top craft beer events, and its success stems from the fact that it’s fundamentally a festival created by brewers, for brewers,” says CBG Communications Manager Carrie Knose Wilson. “We’ve seen collaborations ignite lasting partnerships between brewing teams and bring together breweries in ways that highlight their complementary expertise. Whatever inspires these beer collaborations, the creativity on display at Collaboration Fest is truly impressive.”

Since 2014, Collaboration Fest has united member craft breweries with independent brewing partners ranging from local neighbors to brewers spanning Colorado, teams from coast to coast, and occasional international collaborators. Together, they craft exclusive, limited-edition beers available for the annual fundraiser, which advances the CBG’s mission to promote, protect, and propel independent craft breweries in the State of Craft Beer through advocacy, community, education, and public awareness. 

Notably this year, Cannonball Creek Brewing Co., River North Brewing, and Westbound & Down Brewing are joining forces to create the festival’s welcome beer. All three breweries received Brewery of the Year honors at the 2025 Great American Beer Festival and decided to create a West Coast IPA which will be the welcome beer at the festival. 

“Colorado has long been considered the State of Craft Beer—and with Brewery of the Year honors awarded in the same year at GABF to Westbound & Down, River North, and Cannonball Creek, that claim has never been stronger,” says Westbound & Down CEO and Director of Brewing Operations Jake Gardner. “We’re honored to brew this beer in celebration of that achievement and in support of the Colorado Brewers Guild, whose work strengthens and champions independent craft brewers across our state.”

Attendees can purchase Early Entry, General Admission, and Designated Driver tickets via the Collaboration Fest ticketing page. Be sure to pre-order limited edition 2026 Collaboration Fest t-shirts by February 22 for pick up at the festival.

The Colorado Brewers Guild Reveals Beer Lineup for
Collaboration Fest 2026

160+ craft breweries to pour over 120 beers on April 4


DENVER (March 11, 2026)—  The Colorado Brewers Guild (CBG) is proud to announce the full beer lineup for Collaboration Fest, the original collaboration craft beer festival, returning on Saturday, April 4, 2026 at The Westin Westminster (10600 Westminster Blvd, Westminster, CO 80020). Presented by On Tap Credit Union, the festival will feature more than 160 craft breweries pouring more than 120 exclusive beers brewed specifically for this occasion. 

“Collaboration Fest is the only place where you can taste a beer that literally could not exist without two breweries deciding to take a chance together,” says CBG Communications Manager Carrie Knose Wilson. “That spirit of creative risk-taking is what keeps this event special year after year.”

Collaboration Fest is a one-of-a-kind event where craft brewers from near and far team up to push the boundaries of brewing creativity. Since 2014, Collaboration Fest has served as an annual fundraiser supporting the CBG’s mission to promote, protect, and propel independent craft breweries throughout the State of Craft Beer through advocacy, community, education, and public awareness.

The stories behind this year’s beers speak to the soul of what makes Collaboration Fest unlike any other festival. For example, three powerhouse Colorado breweries, Cannonball Creek Brewing Co., River North Brewing, and Westbound & Down Brewing, all recipients of Brewery of the Year honors at the 2025 Great American Beer Festival, collaborated to brew this year’s welcome beer. The West Coast IPA,  named Rocky Mountain Advantage, will be poured at the festival and made available at participating retailers with proceeds of the sale of this beer donated to the Colorado Brewers Guild. The Guild would like to thank BSG, Yakima Chief Hops, and Berkeley Yeast for their support.
 
Beyond the welcome beer, the lineup spans the full spectrum of craft creativity. Adventurous drinkers will find boundary-pushing offerings like a Hazy IPA brewed with pineapple purée, Anchovy hops, and pizza seasonings to evoke a pineapple-anchovy pizza, a Lager brewed with black rice, a beer that’s a blend of West Coast IPA and Spontaneous Ale, and much more. For those who prefer a more traditional pour, not to worry—Collaboration Fest will also have plenty of classic beer styles to go around.
 
“At its heart, Collaboration Fest is about collaboration and community,” says Janelle Herrera, Vice President of Marketing and Business Development, On Tap Credit Union. “After five years of supporting the event as the presenting partner, we continue to be inspired by an industry that believes in working together and giving back. With roots that began in a brewery, we share those same values and believe financial institutions should exist to serve people, not profit from them. Supporting this event allows us to stand alongside the beer community while helping people keep more of their hard-earned money for the experiences that matter most to them.”
 
Attendees can purchase Early Entry, General Admission, and Designated Driver tickets via the Collaboration Fest ticketing page.
