CollabFest: Collaboration, Chaos (the good kind), and a Whole Lot of Root Shoot

  • Mar 31

There are beer festivals… and then there’s Collaboration Fest.


If you’ve been, you know. If you haven’t—imagine over 160 breweries throwing out the rulebook, teaming up, and brewing things they’d never attempt alone. It’s one of the few festivals where the beer list reads more like a group text than a menu. It’s creative, a little chaotic, and exactly how this industry should feel.


We’ll be there Saturday—and a good chunk of what’s pouring started as Root Shoot grain.

Collabfest by the numbers


CollabFest brings together more than 160 breweries, all working together instead of competing, to create over 120 collaboration beers brewed specifically for this one day. Every single beer on the floor is a true collab—at minimum two breweries teaming up, and often quite a few more. Since launching in 2014 as a fundraiser for the Colorado Brewers Guild, the event has continued to grow, with some years pushing past 180 breweries and 130 beers. All of it packed into one room with roughly 2,000 people sampling their way through it.


What makes it actually cool isn’t just the scale—it’s the process behind it. Brewers spend months working together ahead of time, sharing yeast, recipes, and ideas that wouldn’t normally leave their own brewhouse. The result is a lineup of beers you literally can’t find anywhere else. Styles run the full spectrum—from clean, dialed-in lagers to smoked beers, fruit and spice experiments, and the kind of “this probably shouldn’t work” concepts that somehow do.


It’s often called a “brewers’ beer festival,” and that tracks. This one isn’t built around selling beer—it’s built around making it, together. If a beer exists at CollabFest, it’s because someone said, “what if we tried this?” and someone else said, “yeah, let’s do it.”



Exploring Beers with Root Shoot

CollabFest can be a little overwhelming—in the best way. You walk in, grab a glass, look up… and suddenly you’re staring at 120+ beers, all brewed once, all worth trying, and no real roadmap.


So here’s one.


Think of this as your field guide to Root Shoot beers at Collaboration Fest—a way to navigate the room, find the beers built on our grain, and maybe string together a tasting path that actually makes sense (or at least starts that way).


Because while every beer here is a collaboration, these are the ones that start a little further upstream—with barley grown on our farm, malted at Root Shoot, and handed off to brewers who decided to do something interesting with it.


So whether you’re hunting for precision, chasing something weird, or just trying to make a dent in your tasting list, start here:

Why this fest matters


This is collaboration in its purest form. Breweries sharing ideas. Styles getting pushed. Beers that only exist because people decided to work together.


And for us, it’s the full loop: Grain grown here in Colorado, malted here at Root Shoot, pushed into something new by brewers we’re lucky to work with.


Some of these beers are clean and precise.

Some are a little weird.

Some are straight-up “only at CollabFest” energy.

That’s the point.


See you Saturday. If you’re there: Find a Root Shoot beer (there are plenty), talk to the brewers behind it, try something you normally wouldn’t. We’ll be the ones bouncing between lagers and whatever the hell that mushroom Kolsch is. Come say hi!
