Why go
Sourdough is the spine of this downtown Rapid City bakery-cafe: long-fermented loaves and bagels out of the early bake, a case of cinnamon-heavy sweets beside them, and espresso pulled at the same counter. It is a bakery-cafe rather than a bread window, so the loaves come first but the room is set up for people to sit down with them.
A sourdough bakery that started at home
The bakery is run by a husband-and-wife team who came back to Rapid City in 2016 and began baking bread at home, then sold it as a weekend mom-and-pop operation. The business was formed in 2021, opened as a bakery-cafe in May 2022 and moved into its downtown space in June 2025. The owners stay close to the bake, with mixes starting at three or four in the morning and overnight shifts to cover the rest. Sourdough is still the production identity: house loaves, sourdough bagels and Country Bread, with wholesale accounts around the Black Hills taking the same bread off the same bench.
A cafe room, not just a bread rack
The counter works as a full cafe rather than a production bakery with retail racks. Espresso drinks sit beside the loaves, bagels, donuts and cinnamon rolls rather than trailing after them, and the owners put the logic plainly: pastry is better served with coffee. The downtown room is modern with plenty of seating, so it holds a daytime sit-down role as well as a bread pickup. Since the move the kitchen has been widening, with lunch options under discussion and pizza ovens recently arrived, so a savoury side is still taking shape around the bread and the pastry case.
Order the Country Bread, then something cinnamon
Start with Country Bread to understand what the bakery is. Alongside the sourdough loaves and sourdough bagels it carries the whole idea: a family-run operation built on long fermentation, early production and breads repeatable enough to supply a cafe counter and wholesale accounts at once. Then move toward cinnamon. Cinnamon chip bread and take-and-bake cinnamon rolls are the named sweet side of the programme, with donuts and rotating pastries behind them. For a cafe order, pair the pastry with an espresso drink and use the room for a while rather than treating the stop as a quick bread pickup.

Frequently asked questions
What should I order first at The Sour?
Country Bread, the loaf that best explains the bakery. It comes from the same long-fermented sourdough programme as the house loaves and the sourdough bagels, and it is the steadiest thing on the shelf. After that, go to the cinnamon side: cinnamon chip bread or a take-and-bake cinnamon roll, with a donut as the third option.
Can you sit down with coffee at The Sour?
Yes, it works as a cafe as much as a bakery. Espresso drinks are made at the same counter as the bread and pastry, and the downtown room is modern with plenty of seating, so a pastry and a coffee at a table is a normal visit rather than a takeaway afterthought.
