Selling dried sourdough starter in Iowa
What Iowa official sources actually say about selling dried sourdough starter under cottage food law — not named — general non-tcs path — confirm. Last verified 2026-10-15.
If you keep a jar going in Iowa, selling dried sourdough starter is a different cottage-food question than selling bread. The product is flour and water that you fermented, then dried. Official pages almost never use the words “dried starter.” This post only repeats what the current statute, agency page, or extension guide actually says — and where that source is silent.
Dried starter is not automatically a baked good
A loaf is baked. Dried starter is a dry culture. Some states publish a closed allowed-foods list (baked goods, jams, dried herbs). Some allow non-TCS / non-potentially-hazardous foods as a class. A few name baking mixes, dry mixtures, or — in Kansas — dehydrated sourdough starter. We do not stretch a baked-goods line into a dry-culture line unless a source supports that read.

Where in-state sales usually go
Sales cap, registration, allowed foods, and every county — free on Crosodo.
From the Crosodo statute row: Cottage food direct-to-consumer sales only; however, a separate Home Food Processing Establishment (HFPE) license allows indirect retail and wholesale sales of almost any food including perishables.
County zoning, market manager rules, and home-occupation permits still apply on top of the state food rule. Start with the Iowa state guide and your county page.
Labeling
Labels must include: name and address (or phone or email) of the producer, common name of the food, ingredients in descending order of predominance, and the statement 'This product was produced at a residential property that is exempt from state licensing and inspection.' Major allergens must also be identified on the label.

Interstate / shipping across state lines
Cottage-food / homemade-food exemptions are in-state instruments. They do not, by themselves, authorize interstate commerce. Confirm manufactured-food licensing with the state agency and FDA facility registration for your facts. We do not invent a permit name or a fee.
Cottage-food exemptions are state instruments. They do not replace federal rules that apply when food enters interstate commerce. If you want to ship out of state, ask the state manufactured-food program and confirm FDA facility registration for your situation. We do not invent a license name or a fee here.
