Can I make kombucha at home in California?

California's own pages, as ShelfStep read them on September 25, 2026, do not name kombucha or foods like it, so this page cannot tell you whether a home kitchen in California may make it. Ask the California Department of Public Health and your county environmental health department before you make it at home to sell. What the state allows and leaves out in general is on the California page.

What rules does kombucha come under beyond California's?

Outside a home kitchen, ShelfStep's plan reads kombucha as a beverage. The plan's own line for it, a default and not a law:

From there, ShelfStep's standard plan for a beverage has 19 steps. The first 6 help you find out where and how kombucha can be made at all, so they come first:

1.
Write the recipe down with exact amounts
Cost, price, nutrition and the label are all worked out from this. Write it in the units you actually use; ShelfStep converts for the label. What matters is that someone else could make the same batch from what is written.
2.
Decide how it is kept: on a shelf, in the fridge or frozen
The planned storage helps the reviewer assess the process, shelf life and packaging.
In the plan: It decides which rules you follow.
3.
Find out where you are allowed to make it for sale
This finds out whether the state’s rules allow making this in a home kitchen or point to a commercial one — and that changes the cost and the timeline of everything after it. It is much cheaper to find out now than after buying packaging.
In the plan: Your state's home-kitchen rules, in its own words. Whether they cover your product is for your state's agency to say.
4.
Have the pH and water activity of a finished batch measured
These measurements give your reviewer information about the batch; they do not establish safety or storage conditions on their own.
In the plan: The two numbers the acidified-food rules name. Measured on the finished product, once it has settled.
5.
Get a Process Authority's letter on how it is made safe
Ask a qualified reviewer which process and storage conditions your product needs. This is where you ask someone qualified, a Process Authority, to put in writing how the product is made safe. Buyers, insurers and inspectors may ask for that document, and it cannot be obtained after the fact for product you have already sold.
In the plan: Needs the pH first. Their letter sets out the process they ask you to hold to, and the storage line for your label.
6.
Look into FDA registration
Registration is how FDA knows your facility exists; the plan is what an inspector or a buyer’s audit asks to see. Both are far easier to do now than during either.
In the plan: Look into registration with FDA. Any filing your Process Authority letter names belongs here too.

Every step, with its reason and what it typically costs, is on the kombucha page:

1. Write the recipe down with exact amounts 2. Decide how it is kept: on a shelf, in the fridge or frozen 3. Find out where you are allowed to make it for sale 4. Have the pH and water activity of a finished batch measured 5. Get a Process Authority's letter on how it is made safe 6. Look into FDA registration 7. Choose the container and what seals it 8. Shortlist three co-packers or commercial kitchens 9. Work out what one batch, and one unit, costs to make 10. Set up lot codes and a recall plan 11. Make a first full-size batch 12. Find out how long it keeps 13. Get barcodes 14. Draft the label with everything it has to say 15. Set the wholesale and shelf price from the cost 16. Sell it at a market before you scale 17. Get product liability insurance 18. Make the one-page sheet a buyer reads 19. Name your first three stores
