ABOUT THIS DISTILLERY

Rocket Science Meets Grain Science

Westslope Distillery sits on South 2nd Street in Hamilton, Montana, in the heart of the Bitterroot Valley with the Sapphire Mountains rising to the east. Founded by Chris Gallagher, a former aerospace engineer who traded rocket science for grain science after falling in love with craft distilling during travels through Scotland and Kentucky. The distillery opened its doors in 2015, taking over a renovated commercial space that Gallagher and his team transformed into a working distillery complete with custom copper stills and aging room. They focus on small-batch bourbon, rye whiskey, and vodka, using Montana grains whenever possible. Gallagher’s engineering background shows up everywhere in the operation – from the precisely controlled fermentation temperatures to the custom-designed column still that he helped engineer specifically for their grain bills. He spent two years perfecting recipes before opening, working with local farmers to source wheat and corn while sourcing specialty grains from across the region. The operation remains deliberately small-scale, with Gallagher still hands-on in production alongside a tight crew that treats each batch like a science experiment with delicious results. Visitors get an authentic look at craft distilling without the corporate polish – you’re likely to find Gallagher himself running tastings and explaining the technical details that most distillers gloss over. The tasting room has a relaxed, workshop-like feel where the focus stays on the spirits rather than flashy marketing. It’s the kind of place where you’ll learn something new about distillation while sampling spirits that reflect both technical precision and creative risk-taking.

WHAT SETS THEM APART

Aerospace Engineering Precision In Every Batch

Gallagher’s aerospace engineering background creates a distillery that operates more like a precision laboratory than a traditional craft operation. He applies aerospace-level quality control to every step, monitoring fermentation temperatures with the same attention to detail he once used for rocket components. The custom-designed column still incorporates engineering principles that most craft distillers never consider, allowing for more precise cuts and better separation of flavor compounds. Montana’s high altitude and dry climate also create unique aging conditions that concentrate flavors differently than traditional bourbon regions, giving their whiskeys a distinct character that reflects the Big Sky environment.

THE VISITOR EXPERIENCE

Working Lab Atmosphere Not Tourist Polish

You’ll walk into what feels more like a working lab than a polished tasting room, with Gallagher often leading tastings himself and diving deep into the technical aspects of distillation that most places skip over. The space smells like fermenting grain and aging oak, with the copper still dominating the room and production equipment visible throughout the tour. Gallagher loves explaining the engineering behind flavor development, so you’ll learn about things like reflux ratios and congener management alongside traditional whiskey-making knowledge. The tastings focus on understanding how different techniques affect flavor rather than just sampling products.

IS IT WORTH VISITING

For Science-Minded Spirits Enthusiasts

This is perfect for spirits enthusiasts who want to understand the science behind distillation rather than just drink and socialize. If you’re fascinated by the technical side of craft spirits or you’re a home distiller looking to learn advanced techniques, Gallagher’s engineering approach offers insights you won’t get elsewhere. It’s not the place for casual tourists looking for Instagram moments or party atmospheres – the appeal lies in the educational depth and the chance to taste spirits made with aerospace-level precision. Bourbon geeks and science-minded drinkers will find this absolutely fascinating.

⚠️ VISITING TIPS

Call ahead since Gallagher runs a small operation and may be deep in production when you arrive. Ask specifically about his engineering background and how it influences their processes – he lights up when discussing the technical details and you’ll get insights into distillation science that most places can’t provide. The best time to visit is during weekdays when production is active and you can see the stills in operation. Don’t expect a slick presentation – bring genuine curiosity about the craft and be prepared for a more educational experience than entertainment-focused one.

FREQUENTLY ASKED QUESTIONS

Westslope Distillery — Visitor FAQ

What makes an aerospace engineer’s approach to distilling different?
Chris Gallagher applies aerospace-level precision to every aspect of production, from monitoring fermentation temperatures with scientific accuracy to custom-designing stills using engineering principles. This technical approach allows for more precise control over flavor development and consistency than traditional craft distilling methods.
How does Montana’s climate affect the aging process?
The high altitude and dry climate create unique aging conditions that concentrate flavors differently than traditional bourbon regions. The environment leads to different rates of evaporation and wood interaction, giving their whiskeys a distinct character that reflects the Big Sky terroir.
Should I expect a typical distillery tour experience?
Not at all – this is more like a technical education session than a polished tourist experience. Gallagher focuses on the science and engineering behind distillation, so come prepared for detailed explanations about reflux ratios and congener management rather than just casual sampling and socializing.
