Can I sell hot sauce under California's cottage food law?
Updated
On this page6
No. California is unusually direct about it: the California Department of Public Health's cottage food questions page asks "Why can't I make pickles, hot sauce, or other canned foods?" and answers that the risk of botulism in low-acid and acidified foods keeps them off the approved list [1]. Only foods on that list may be made in a Class A or Class B cottage food operation, and the list states that pickled products and acidified foods such as chutneys and salsas are not approved [2]. To sell hot sauce in California you need a commercial kitchen or a copacker. This page explains why the usual workarounds do not apply and where to start.
What the state says, in its own words
CDPH's reasoning is the one any process authority would give. In its answer about hot sauce, the department writes that "When dealing with a low-acid or acidified food, there is the risk of Botulism," explains that a sealed container creates the low-oxygen conditions the bacteria need, and notes that a single mistake could seriously harm or kill a customer [1]. The cottage program has no safe process for these foods, so it does not allow them [1].
The same page rules out salsa and pepper jelly [1]. The approved list, as published by UC Agriculture and Natural Resources from the CDPH list of February 2025, adds that foods containing meat and "any food that requires refrigeration" are not approved cottage foods [2].
Why the common workarounds fail
| Idea | Why it does not work under the cottage law |
|---|---|
| Keep the sauce refrigerated | Foods that need refrigeration are excluded from the approved list [2] |
| Ferment instead of adding vinegar | Only listed foods are allowed, and fermented vegetables are not on the list; CDPH's answer covers canned foods generally [1] [2] |
| Call it a pepper jelly | Pepper jelly is specifically not an approved cottage food [1] |
| Get a pH test or a process review | The cottage program has no test or approval path for acidified foods; the restriction is by product, not by pH [1] [2] |
A process authority review is still the right next step, but for a licensed kitchen, not a home one. The fermented sauce page explains why this book treats a ferment finished with vinegar as an acidified food, which in California changes nothing about the cottage answer.
Making sauce to sell in California
The path runs through a commercial facility: a shared or commissary kitchen you rent, your own licensed space, or a copacker who makes the sauce for you. The order of work is roughly the same in each case:
- Turn your recipe into a weighed formula and send it to a process authority, who sets the critical limits such as maximum pH and fill temperature.
- Choose the kitchen, because the state permit attaches to the place where the sauce is made. The kitchen or copacker page compares the options, and the copacking page covers working with one.
- Get the state permit for a food processor. For a food that is not on the cottage list, CDPH tells producers to contact their city or county environmental health department or the CDPH Food and Drug Branch at 1-800-495-3232 or FDBfood@cdph.ca.gov [1]. This page could not confirm the exact name of the processor registration from a CDPH page reviewed; ask the Food and Drug Branch which one applies to a bottled acidified sauce.
- Complete the federal steps for an acidified food: facility registration and filing your process with FDA. The licensing page puts the federal, state and local layers in one list.
Label rules for a commercial sauce follow federal law; see the federal labeling page.
Who runs what in California
Two levels share the work. CDPH sets the approved list but does not itself register or permit cottage food operations; those registrations and permits belong to local enforcement agencies, usually the county environmental health department [1]. For a processed food made in a commercial kitchen, the Food and Drug Branch is the state contact [1].
Confirm with CDPH and your county
Start with the CDPH cottage food questions page and the Food and Drug Branch contacts listed there [1], and check the current approved list through UC ANR's cottage food site [2]. This page was last verified October 2026. To see the states that do allow home sauce, read selling hot sauce in your state; to begin the commercial path, read finding a process authority.
