We’re dropping a brand-new Project X Series beer — Motor Skills — and celebrating the long-awaited annual return of Sin Tax Imperial Peanut Butter Stout. Both will be hitting our taprooms in CA and ID, as well as landing in distro in cans and on draft. The rollout in distro begins this week, but out tap rooms will be serving them. up at our double release party on 11/29.
These two beers couldn’t be more different, but weirdly, releasing them together makes perfect sense. One is fresh experimentation; the other is deep-rooted nostalgia. Together, they pretty much sum up who we are as a brewery.
Motor Skills: A New Project X Hazy Built Around Expression, Texture & Art
Motor Skills has been an incredibly fun project for us — not just from a brewing standpoint but a creative one. This release is part of our ongoing Project X Series, where we get to play with ingredients, techniques, and ideas that don’t always fit into the core lineup. It’s also an artist collaboration, featuring original work from the insanely talented @midmindarts. If you’ve seen the label, you know his style immediately — intricate, surreal, colorful without being loud, and impossible to forget. His artwork sets the tone for the beer: fluid, expressive, and layered. With over 100k followers on Instagram alone, he's kind of a big deal.

“Sometimes the best way to navigate the chaos is to not take life too seriously and find joy in the little things. Do stuff that brings you out of your comfort zone, you may find what you’re looking for in a place you’d never expect.” -Cade
On the brewing side, we built Motor Skills around a vibrant four-hop lineup:
Amarillo — bright orange peel, soft floral character, and a little sweet melon
Citra — classic grapefruit, lime zest, and big tropical aromatics
Mosaic — blueberry, resin, pineapple, and that deep “berry-tropical” thing Mosaic is famous for
Nelson Sauvin — white grape, gooseberry, and a vinous, almost sauvignon-blanc edge
Those four together create a really saturated, modern hazy profile: juicy citrus, lush tropical fruit, soft grape and berry, a rounded, pillowy finish. We pushed the dry hop hard, aimed for a soft texture, and kept the bitterness low so the hop expression could shine without getting harsh. The end result is layered and bright, but still super drinkable — exactly what we aim for with the Project X Series.

The Return of Sin Tax: A Beer With History
Now, let’s talk Sin Tax — because for a lot of people, this beer is Mother Earth.
Sin Tax has been with us for over a decade now, and it’s one of the first beers that helped define who we were in the early days. Back when we brewed the original batch, the idea of a peanut butter stout was far from common. There weren’t shelves full of them. It wasn’t a gimmick style. We didn’t do it for novelty — we did it because we loved the idea of layering natural peanut butter onto a real, robustly built Imperial Stout, and people immediately connected with it.
Sin Tax built its following the old-school way: pint by pint, recommendation by recommendation, until it became one of those beers people asked for year-round. Even now, every fall we get messages like, “When is Sin Tax coming back?” It’s become a seasonal ritual — like the unofficial start of stout season. What makes it special is the balance. We build it on a big base of roasty, chocolatey malts, then blend in natural peanut butter flavor in a way that enhances the beer instead of taking it over. No artificial flavors. Just a decadent, warming Imperial Stout with depth, creaminess, and that unmistakable peanut-butter finish that lingers just long enough.

Releasing these two beers together — one brand new and expressive, the other a returning classic with real history behind it — feels like the perfect way to head into the season.
Both Motor Skills and Sin Tax hit our SoCal and Idaho taprooms on Saturday, with wider distribution rolling out in November and December. Sin Tax, especially, tends to fly once it hits shelves, so if it’s on your annual must-have list, plan ahead.
You can always track down both beers using our beer finder. Here’s to the new, the old, the creative, and the nostalgic.
