Can I sell kombucha from home? A 50-state guide.
Kombucha under US cottage food law: 1 states allow it outright, 47 allow it with conditions, 3 prohibit it. Full national breakdown with statute links and the food-safety reasoning behind each verdict.
Every cottage food question comes down to two things: what's your state's tier, and does the food you want to sell fit inside it. Kombucha is a good example because the answer genuinely depends on where you live.
kombucha: 1 states allow it outright, 47 allow it conditionally, and 3 prohibit it under their cottage food exemption. The exact requirements vary by state — see the table below.
Why the law treats it this way
Acidified foods (pH ≤ 4.6) inhibit Clostridium botulinum — the highest-risk pathogen for home preserving. Documented pH via calibrated meter (not pH strips) is the standard proof of safety.
What can go wrong in a home kitchen
Botulism if pH drifts above 4.6. Fresh chile / garlic infusions in oil are prohibited almost everywhere because they can support botulism growth. Many states require a process authority (usually a state university food-science lab) to review the recipe.
Where kombucha is a straightforward yes
1 jurisdictions allow kombucha outright: Wyoming. In each of these states you can sell direct-to-consumer without a scheduled process, acidified-foods license, or commercial-kitchen requirement — just the standard cottage food label and (in most states) a sales cap.
Kombucha: conditional in most states
47 of 51 jurisdictions treat kombucha as conditional — usually because the food needs a pH test, a scheduled process, a water-activity check, or acidified-foods training before you can sell it under the cottage food exemption. A few examples:
- Alaska
- Acidified / fermented foods usually require documented pH ≤ 4.6 or a process authority letter.
- Alabama
- Acidified / fermented foods usually require documented pH ≤ 4.6 or a process authority letter.
- Arkansas
- Acidified / fermented foods usually require documented pH ≤ 4.6 or a process authority letter.
- Arizona
- Acidified / fermented foods usually require documented pH ≤ 4.6 or a process authority letter.
- Colorado
- Acidified / fermented foods usually require documented pH ≤ 4.6 or a process authority letter.
The full breakdown for all 47 conditional states is in the state-by-state table — every state's note is different.
Where kombucha is prohibited
3 jurisdictions prohibit kombucha under their cottage food exemption. Selling it in these states requires a licensed commercial kitchen and, usually, a separate food-processor license. Examples:
- Florida
- Fermented beverages require FDA / DBPR alcohol beverage regulation review.
- California
- Fermented beverages are not on the California CFO approved list.
- Massachusetts
- Not permitted from a residential kitchen.
What to do next
- Check your state's tier. State cottage food law is the floor; find your state on the state directory and confirm the tier plus the sales cap.
- Read your specific verdict. The kombucha state-by-state table tells you exactly what your state allows and links to the statute.
- Verify with your local health department. Even in states that allow kombucha outright, county zoning and city home-occupation rules can add a permit or restriction. State law rarely preempts local zoning.
- Label correctly. Every cottage food state requires a labeled product: business name, address, ingredient list, allergen disclosure, and a "made in a home kitchen" disclaimer. Exact wording varies — see our state labeling breakdown for your state.
- Stay under the cap. Most states cap annual gross sales under the cottage food exemption. Track revenue from day one; graduating to a licensed kitchen is a real cost and a real transition, not something to trip into.
