Ohm Coffee Roasters to Open in Sonoma on October 24

Ohm Coffee Roasters will open its second brick-and-mortar location in the former Monday Bakery space in Sonoma on Thursday, October 24, two weeks after the Napa location’s doors open.

Ohm Coffee founder Derek Bromley was looking for retail space to expand his business. When Monday Bakery closed its Sonoma and Napa locations, as well as a production facility on Jefferson Street, on Aug. 25, Bromley jumped at the opportunity.

Ohm Coffee Roasters is known in Napa for serving coffee by the truckload for nearly a decade and then expanding to Jefferson Street, where Bromley opened a roastery in 2023.

Bromley expanded the business from an espresso truck at the Napa Farmers Market to the Jefferson Street facility, where he hosted wine tasting-inspired coffee experiences, and now with two new locations to serve his exceptional coffee.

“We’re moving at a breakneck pace — Napa opened less than six weeks after Monday Bakery closed its doors — and customer response has been overwhelmingly positive so far,” Bromley said in an email to the Index-Tribune.

Ohm is no ordinary coffee shop; Bromley’s mixes are named after guitar amps and styles, a combination of the founder’s passions. The businessman is also a musician and his brand was inspired by the unique desire to connect sound and flavor through coffee.

Ohm Coffee Roasters will open its doors at 117 East Napa Street this Thursday. Normal store hours have not yet been announced. The Napa location is located at 1412 Second Street.
