An early-morning fire on June 29 damaged The Mill at 736 Divisadero, the café and bread-making hub behind Josey Baker Bread, closing the 13-year NoPa institution indefinitely. It's the second Divisadero business shuttered by fire in under three weeks.

A fire broke out at The Mill on Monday around 3:20 a.m., damaging the rear kitchen and bakery area of the 736 Divisadero building and closing the café indefinitely — the second business on the Divisadero corridor to be shuttered by fire in under three weeks.

The San Francisco Fire Department said in a Facebook post that crews successfully contained the fire to the building. Video from the scene shows firefighters tearing into the back wall and ceiling of the kitchen and baking area, where the visible damage concentrated.

By late morning Monday, The Mill had posted to Instagram: "Last night we had a fire and will be closed until further notice while we get everything sorted. Everyone is safe, just in shock. Thank you for your support as we figure out how to move forward."

The Mill opened roughly 13 years ago as a collaboration between Josey Baker Bread and Four Barrel Coffee — the business is still registered with the City under the Fourbarrel Coffee entity at 736 Divisadero. Over time it became the retail and production centerpiece of Josey Baker Bread, the bakery operation whose sourdough loaves the San Francisco Chronicle recently named the best in the Bay Area. Beyond café service, the space functions as the central bread-making hub for JBB's sourdough and Wonder Bread loaves, and hosts bread- and pizza-making classes that draw regulars from the NoPa and Alamo Square neighborhoods.

The scope of the production interruption will depend on how quickly the space can be made operational again. No reopening timeline has been set.

The fire arrives 18 days after a chimney flue fire closed Che Fico at 838 Divisadero on June 11, leaving two well-known rooms on the same block now shuttered for fire damage simultaneously. For a corridor that has spent the last decade building a reputation as one of the city's most consistent stretches of restaurants and food businesses, it's a hard couple of weeks.
