About Mill City

Mill City Roasters builds great commercial coffee roasters, but we’ve always been about much more than machinery.

Since 2013, Mill City Roasters has helped launch over 2500 commercial roasteries providing commercially focused education and training from our SCA Certified Campus, CSA, and UL compliant industrial quality coffee roasters uniquely optimized for the production of specialty coffee, and the best tech and after-sale support in the entire industry to help our owners keep their roasters running and their businesses growing year after year.

Through our free Roaster School series on YouTube, we’ve coached the entire world to better coffee. Our Mill City Roasters channel boasts over 15000 subscribers and has accumulated over 8 million minutes of viewership worldwide.

On the mechanical side of things, we offer some of the heaviest constructed, most powerful, most capable, and most flexible roasting systems ever built. We know we’re supposed to make a big deal about building the “Perfect Roaster”, but we and our customer's value performance over hyperbole. We design for reliability, ease of use, ease of maintenance, and ease of repair. You’ll find our machines in some of the best roasteries in the world, but we’re almost more proud as such a young company to have been chosen as the exclusive sponsor of the US Roasting Championship for the 3rd year in a row providing both sample and production roasters for the live roasting events.

We’re passionate about roast and coffee quality and we think that better coffee creates more demand for better coffee. We’re in this with you and we’re growing the industry together by remaining as committed to your success as we are our own.
