What North Carolina Food Regulators Look For When They Review Your Kombucha Operation
Kombucha sits in an unusual regulatory spot in North Carolina, and understanding it correctly saves producers from applying the wrong rulebook. In most states, kombucha is treated as an acidified food subject to 21 CFR Part 114 and its Better Process Control School training requirement. North Carolina takes a different view. The state, through NC State Extension acting as its recognized food authority, classifies naturally fermented kombucha as a fermented food that is exempt from acidified food regulations. That single classification changes which framework governs your operation, though it does not reduce the underlying food safety expectations one bit.
Packaged kombucha in North Carolina is regulated by the North Carolina Department of Agriculture and Consumer Services (NCDA&CS), specifically the Food and Drug Protection Division’s Food Program. This is the agency that inspects food manufacturing facilities and packaged food operations. County health departments handle prepared, ready-to-eat foods served on-site, but bottled kombucha sold in stores or shipped to customers falls under NCDA&CS. The Food and Drug Protection Division conducts routine unannounced inspections of food manufacturers, and its Food Compliance Office can be reached at (984) 236-4820, with the broader division at (919) 733-7366.
When an NCDA&CS Food Regulatory Specialist inspects your kombucha operation, they are verifying that your facility meets Good Manufacturing Practices under 21 CFR Part 117, that you have a food safety plan appropriate to your product, that your process reliably produces a safe finished beverage, and that your records back it up. Because kombucha is fermented and unpasteurized in most cases, it requires refrigeration, and that fact carries significant weight in how you are allowed to produce it. Products that require refrigeration for safety cannot be made in a home kitchen in North Carolina. They must be produced in a commercial facility under the department’s routine inspection program. Before you invest in equipment, contact the NCDA&CS Food Compliance Office to confirm your facility and process meet requirements.
Why Kombucha Falls Under Preventive Controls Rather Than Acidified Food Rules in North Carolina
The classification of kombucha as a fermented food rather than an acidified food is not a technicality. It determines your entire compliance pathway, so it is worth understanding the logic.
An acidified food, under 21 CFR Part 114, is a low-acid food to which acid or acidic ingredients are added to bring the pH down to 4.6 or below. Pickles and many hot sauces fit this definition because vinegar or another acid is added to a base that would otherwise be low-acid. Kombucha is different: the acid is produced by the fermentation itself, as the symbiotic culture of bacteria and yeast converts sugar into organic acids. Because the acidity comes from fermentation rather than added acid, North Carolina treats naturally fermented kombucha as a fermented food and exempts it from the acidified food regulations, including the Better Process Control School requirement that applies to acidified food operations. If you were to add vinegar or another acid to your kombucha, that could change the classification, so any process that introduces added acid should be reviewed with NCDA&CS.
Being exempt from acidified food rules does not mean being exempt from food safety regulation. Kombucha producers still fall under the FDA’s preventive controls framework established by the Food Safety Modernization Act (FSMA). Human food facilities registered with the FDA must implement a written food safety plan that identifies hazards and outlines preventive controls under 21 CFR Part 117. FDA facility registration is required for food processors, and NCDA&CS partners with the FDA to enforce these state-adopted federal regulations. So your HACCP-style documentation obligation comes through the preventive controls pathway rather than the acidified foods pathway, but the practical result, a written plan with monitored control points and records, is much the same.
North Carolina also relies on a process authority evaluation to confirm that your specific product and process are safe. NC State University’s Food Science Department analyzes products for risk and issues a process authority letter, which NCDA&CS uses to confirm your product’s classification and safety parameters. Securing this evaluation early establishes, on paper, that your kombucha reaches and holds the pH that keeps it safe, and it documents the scientific basis for your critical limits.
Finally, the alcohol threshold governs everything regardless of classification. Kombucha remains a non-alcoholic food only while it stays below 0.5% alcohol by volume. Above that, it becomes an alcoholic beverage subject to federal Alcohol and Tobacco Tax and Trade Bureau (TTB) regulation and North Carolina alcohol licensing. Because unpasteurized kombucha keeps fermenting after packaging, especially without refrigeration, controlling that drift is both a food safety issue and a legal one.
The Critical Control Points Your North Carolina Kombucha Process Must Monitor
Even under the preventive controls framework, kombucha’s food safety rests on two measurable control points, each tied to a numeric limit that inspectors expect to see documented per batch. Your food safety plan must reflect your actual recipe and process, because fermentation behavior shifts with tea type, sugar concentration, temperature, and starter volume.
CCP 1: Fermentation pH. Acidification through fermentation is the primary food safety control in kombucha. Driving the pH down inhibits pathogenic bacteria and molds. Your target finished pH sits in the range of roughly 2.5 to 4.2, and it must stay at or below 4.6 to be considered safely acidic. Measure it with a calibrated pH meter rather than test strips, because the accuracy of your safety case depends on this reading. Your standard operating procedures must describe how employees measure and record pH on a log and how they calibrate the meter. Using at least 10% fermented starter liquid from a previous batch is a widely accepted practice that drives the pH down quickly at the start, shortening the window when a young, higher-pH batch is vulnerable. A batch that has not reached its target pH within the timeframe your plan specifies needs a documented corrective action before it moves forward.
CCP 2: Alcohol by Volume. Keeping finished kombucha below 0.5% ABV is what keeps your product legally a food rather than an alcoholic beverage. This is monitored at packaging and, ideally, verified across the product’s shelf life, since live cultures keep producing alcohol after the bottle leaves your facility. Refrigeration is the standard control: keeping unpasteurized kombucha cold slows fermentation and limits alcohol production. Your plan should specify the ABV testing method, the point at which testing happens, and the corrective action for a batch that tests at or above the threshold. A “Keep Refrigerated” instruction on the label is part of the control strategy, because refrigeration is central to keeping ABV controlled through distribution.
Beyond these two control points, your prerequisite programs carry real weight. Written cleaning and sanitizing procedures for equipment, and a documented process instruction sheet describing how you make kombucha safely, are expected under the Good Manufacturing Practices in 21 CFR Part 117. NCDA&CS inspectors treat these prerequisite documents as part of the overall system, not as optional extras.
Keeping Your Kombucha Operation Compliant Between NCDA&CS Inspections
NCDA&CS conducts routine unannounced inspections, so your records need to be inspection-ready at all times rather than assembled in advance of a known visit. Food Regulatory Specialists collect samples for laboratory analysis during inspections and investigate consumer complaints, which means both your documentation and your actual product can be tested at any point.
The discipline that matters most between inspections is real-time record keeping. Your pH log needs an entry for every batch, recorded when the measurement is taken, with the actual reading rather than a target value written down after the fact. Inspectors can usually tell when a log has been filled in at the end of a week, because identical readings across many batches with no natural variation is a red flag that invites deeper scrutiny. The same applies to your ABV records and your pH meter calibration log. A meter that has not been calibrated on the schedule your plan specifies calls into question every reading taken since the last verified calibration.
Recipe and process changes need attention before they are implemented, not after. Established operations should contact the NCDA&CS Compliance Office before introducing new products to the market to determine whether additional regulations or inspection apply. If you change your tea blend, adjust sugar concentration, alter fermentation time or temperature, switch starter sources, or introduce any added acid, the safety profile and even the classification of your product can shift. A significant change can warrant a fresh process authority evaluation from NC State and an update to your food safety plan.
FDA facility registration must be kept current on the schedule the FDA sets, and lapsing it is a federal compliance gap independent of your relationship with NCDA&CS. Because North Carolina does not issue a state manufacturing license or permit for most packaged foods, producers sometimes assume there is nothing to maintain. That assumption is a mistake: your FDA registration, your food safety plan, and your inspection readiness are the ongoing obligations even in the absence of a state permit.
Where North Carolina Kombucha Producers Most Often Run Into Trouble
The recurring compliance failures for kombucha operations in North Carolina cluster around a few predictable themes, several of them specific to the state’s regulatory structure.
Trying to produce unpasteurized kombucha in a home kitchen is the most fundamental error. Because unpasteurized kombucha requires refrigeration, it is a high-risk product that cannot be made at home under North Carolina’s home processing rules. It must be produced in a commercial facility subject to routine inspection. Producers who assume the state’s relatively accessible home processing program covers kombucha are mistaken, and starting home production of a refrigeration-dependent beverage is a violation from the outset.
Incomplete or missing pH records are the leading documentation finding. Every batch needs its own pH entry tied to a date and a batch identifier. Operations that test the first batch of a production day and assume the rest will match will find their records do not survive inspection scrutiny. If your process is reliable, per-batch testing confirms it. If something shifts unnoticed, the testing is what catches it before product ships.
ABV drift is the failure most specific to kombucha. A batch that tested at 0.4% at packaging can climb past 0.5% if it sits warm on a loading dock or a store shelf without refrigeration. When a regulator or a distributor tests product in the field and finds it over the line, the producer faces a problem that is simultaneously a food safety issue and an alcohol licensing issue. Building refrigeration controls into your transport and storage instructions, and documenting them, is the defense. The “Keep Refrigerated” label is part of your control strategy, not a suggestion.
Missing or outdated process authority documentation is a gap that catches producers who set up their process once and never revisit it. Your process authority letter from NC State establishes that your product reaches a safe pH, and it needs to reflect your current recipe and process. A letter that describes a formulation you no longer use does not support your food safety plan, and an inspector reviewing a mismatch between your documentation and your actual process will treat it as a deficiency.

Bottom Line
North Carolina classifies naturally fermented kombucha as a fermented food that is exempt from acidified food regulations, which spares producers the Better Process Control School requirement but routes them into the FSMA preventive controls framework under 21 CFR Part 117 instead. Packaged kombucha is regulated by NCDA&CS through routine unannounced inspections, backed by a process authority evaluation from NC State that confirms your product’s safety parameters. Because unpasteurized kombucha requires refrigeration, it cannot be made at home and must be produced commercially. Whatever the classification, the food safety fundamentals are unchanged: keep the pH at or below 4.6, keep the ABV below 0.5%, and control both with real measurement rather than assumption. Confirm your classification with NCDA&CS, secure your process authority letter, keep your FDA registration current, and build the daily logging habit from your first batch.
FAQ
- Is kombucha considered an acidified food in North Carolina? No. North Carolina, through NC State Extension acting as its food authority, classifies naturally fermented kombucha as a fermented food that is exempt from acidified food regulations under 21 CFR Part 114. This is because the acidity comes from fermentation rather than added acid. However, kombucha producers still fall under the FDA’s preventive controls framework (21 CFR Part 117) and NCDA&CS inspection. If you add vinegar or another acid to your kombucha, the classification could change, so review any added-acid process with NCDA&CS.
- Can I make and sell kombucha from my home in North Carolina? Generally no, if it is unpasteurized. North Carolina’s home processing program only allows low-risk, shelf-stable products, and unpasteurized kombucha requires refrigeration, which makes it a high-risk product that must be produced in a commercial facility under NCDA&CS routine inspection. Producers who assume the home processing program covers kombucha are mistaken.
- Which agency regulates kombucha in North Carolina? Packaged kombucha sold in stores or shipped to customers is regulated by the North Carolina Department of Agriculture and Consumer Services (NCDA&CS), Food and Drug Protection Division, Food Program. The Food Compliance Office can be reached at (984) 236-4820. County health departments regulate prepared, ready-to-eat foods served on-site, but bottled kombucha falls under NCDA&CS.
- Do I need an alcohol license to sell kombucha in North Carolina? Only if your kombucha reaches or exceeds 0.5% alcohol by volume. Below that threshold it is regulated as a non-alcoholic food. At or above 0.5% ABV it becomes an alcoholic beverage subject to federal TTB regulation and North Carolina alcohol licensing. Because unpasteurized kombucha keeps fermenting after packaging, especially without refrigeration, controlling ABV through cold storage and testing is essential to staying under the line.
