What Ohio Food Safety Inspectors Look For When They Review Your Kombucha Operation
Kombucha’s regulatory treatment in Ohio hinges on a detail most producers never think about until an inspector raises it: whether the finished product is refrigerated or shelf-stable. That single characteristic determines which rulebook governs your operation, because Ohio’s legal definitions treat refrigerated and shelf-stable acid products very differently. Getting this right from the start saves you from applying the wrong compliance framework and building your process around the wrong requirements.
Commercial kombucha in Ohio is regulated by the Ohio Department of Agriculture (ODA), Division of Food Safety. The division can be reached at 614-728-6250 or foodsafety@agri.ohio.gov, and it operates out of Reynoldsburg. ODA inspects food processing establishments and issues a certificate of registration under Ohio Revised Code Chapter 3715, the state’s pure food and drug law. When an ODA inspector reviews your kombucha operation, they are verifying that your facility meets Good Manufacturing Practices, that your process reliably produces a safe finished beverage, that your pH and alcohol are controlled and documented, and that your labeling is accurate and not misleading.
The first thing to understand is that kombucha cannot be produced under Ohio’s Cottage Food Production Operation exemption. That exemption, defined in Ohio Revised Code Chapter 3715, is limited to non-potentially-hazardous foods like baked goods, jams, jellies, and candy. It explicitly does not cover acidified foods, low-acid canned foods, potentially hazardous foods, or beverages. Kombucha requires refrigeration and is a fermented beverage, so it falls outside the cottage food list entirely. You cannot brew kombucha at home and sell it under the cottage food rules. It must be produced in a facility registered and inspected by ODA. Before you invest in equipment or sign a lease, contact the ODA Division of Food Safety to confirm your facility and process meet requirements.
Why Refrigeration Determines Whether Ohio Treats Your Kombucha as a Cannery Product
Here is where Ohio genuinely differs from many other states, and it is worth understanding the logic because it shapes everything downstream.
Ohio Revised Code Chapter 913 defines acidified foods as low-acid foods to which acid is added to bring the finished equilibrium pH to 4.6 or below. Crucially, that same statute states that acidified foods do not include foods that are stored, distributed, or retailed under refrigeration. In other words, under Ohio law, a product held under refrigeration is not classified as an acidified food for cannery purposes, even if its pH is well below 4.6. This matters enormously for kombucha, because most kombucha is sold unpasteurized and refrigerated.
The practical consequence is a fork in the road. If your kombucha is refrigerated, which describes nearly all live, unpasteurized kombucha, it is not a cannery product and does not trigger the acidified foods cannery pathway that requires Better Process Control School training, a process authority evaluation, FDA cannery registration, and a filed scheduled process. Instead, your refrigerated kombucha is regulated as a food processing establishment under ODA, requiring facility registration, inspection, and compliance with Good Manufacturing Practices. This is a lighter regulatory path than the cannery route, but it is not no regulation.
If, on the other hand, you produce a shelf-stable kombucha, meaning it is pasteurized or otherwise made stable at room temperature and sold without refrigeration, the calculus changes. A shelf-stable acid beverage packed in hermetically sealed containers can fall under the cannery and acidified foods requirements in Ohio Revised Code Chapter 913, which incorporates the FDA’s acidified foods regulations at 21 CFR 114. That pathway requires attending Better Process Control School, having your product evaluated by a process authority, registering with the FDA as a cannery, and filing your scheduled process with the FDA before ODA will inspect. The decision to make your kombucha shelf-stable is therefore not just a shelf-life choice: it is a regulatory choice that pulls in a substantially heavier set of requirements.
The alcohol threshold applies regardless of which path you are on. Ohio’s own definitions carve alcoholic beverages out of the low-acid food category, and 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 Ohio Division of Liquor Control oversight. 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 Ohio Kombucha Process Must Monitor
Whichever regulatory path your kombucha follows, the underlying food safety rests on two measurable control points, each tied to a numeric limit that inspectors expect to see documented per batch. Your process documentation must reflect your actual recipe, 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 process 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. In Ohio, refrigeration does double duty, because it also keeps your product outside the acidified foods cannery definition. Your process 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.
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 Good Manufacturing Practices. ODA inspectors treat these prerequisite documents as part of the overall system, not as optional extras.
Keeping Your Kombucha Operation Compliant Between ODA Inspections
ODA registration and inspection are ongoing obligations, not a one-time hurdle. Food processing establishment registration must be maintained, and all food products, including those from registered establishments, are subject to food sampling by ODA to determine whether a product is misbranded or adulterated. That means your product can be pulled and tested at any point, so your labeling and your actual pH and alcohol content need to hold up to independent verification.
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 process specifies calls into question every reading taken since the last verified calibration.
Process changes require attention before they are implemented, not after. The most consequential change in Ohio is a shift from refrigerated to shelf-stable production, because that move can pull your product into the acidified foods cannery pathway with its Better Process Control School, process authority, and FDA filing requirements. Recipe changes matter too: altering your tea blend, sugar concentration, fermentation time, temperature, or starter source can shift your product’s safety profile. If you introduce added acid rather than relying on fermentation alone, that can also change how your product is classified. Any of these changes should prompt a conversation with ODA before you proceed.
FDA facility registration must be kept current on the schedule the FDA sets, and if you operate on the shelf-stable cannery pathway, your scheduled process filing must remain accurate. Lapsing either is a federal compliance gap independent of your ODA registration.
Where Ohio Kombucha Producers Most Often Run Into Trouble
The recurring compliance failures for kombucha operations in Ohio cluster around a few predictable themes, several of them specific to the state’s refrigeration-based classification.
Trying to sell kombucha under the cottage food exemption is the most fundamental error. The Cottage Food Production Operation exemption does not cover beverages, acidified foods, or products requiring refrigeration, and kombucha is all three. Producers who assume Ohio’s accessible cottage food path covers their kombucha are mistaken, and selling home-brewed kombucha under that exemption is a violation from the outset.
Misjudging the refrigerated versus shelf-stable line is the failure most specific to Ohio. A producer who starts refrigerated, then decides to pasteurize and sell shelf-stable product to widen distribution, has potentially moved into the acidified foods cannery pathway without realizing it. Making that move without the Better Process Control School training, process authority evaluation, and FDA process filing that the cannery route requires is a serious compliance gap.
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 that carries a double penalty in Ohio. A batch that tested at 0.4% at packaging can climb past 0.5% if it sits warm without refrigeration, turning a food into an alcoholic beverage in the eyes of the TTB and the Ohio Division of Liquor Control, and simultaneously undermining the refrigeration that keeps your product outside the cannery definition. Building refrigeration controls into your storage and transport, and documenting them, is the defense on both fronts. The “Keep Refrigerated” label is part of your control strategy, not a suggestion.

Bottom Line
Ohio’s treatment of kombucha turns on a single legal distinction that many producers miss: refrigerated products are excluded from the state’s acidified foods cannery definition. That means refrigerated, unpasteurized kombucha is regulated as a food processing establishment under ODA, a lighter path than the cannery route, while shelf-stable kombucha can pull in the full acidified foods requirements including Better Process Control School, a process authority evaluation, and an FDA process filing. Cottage food is not an option for kombucha in either case. Whichever path applies, the food safety fundamentals hold: keep the pH at or below 4.6, keep the ABV below 0.5%, and control both with real measurement rather than assumption. In Ohio, refrigeration is doing more work than you might think, so confirm your classification with ODA before you build your process, and keep your records honest from the first batch.
FAQ
- Can I make and sell kombucha from my home in Ohio? No. Ohio’s Cottage Food Production Operation exemption covers only non-potentially-hazardous foods like baked goods, jams, and candy. It explicitly excludes beverages, acidified foods, and products requiring refrigeration, and kombucha is all three. Commercial kombucha must be produced in a facility registered and inspected by the Ohio Department of Agriculture, Division of Food Safety, reachable at 614-728-6250.
- Does refrigerated kombucha count as an acidified food in Ohio? No, and this is an important Ohio-specific point. Ohio Revised Code Chapter 913 states that acidified foods do not include foods stored, distributed, or retailed under refrigeration. Because unpasteurized kombucha is refrigerated, it falls outside the acidified foods cannery definition and is instead regulated as a food processing establishment. If you make a shelf-stable, non-refrigerated kombucha, it can fall under the acidified foods cannery pathway, which requires Better Process Control School, a process authority, and FDA process filing.
- What pH does my kombucha need to reach to be safe in Ohio? Your finished kombucha should reach a pH in the range of roughly 2.5 to 4.2 and must stay at or below 4.6 to be considered safely acidic. Measure it with a calibrated pH meter rather than test strips, and record it for every batch. This applies regardless of whether your product is refrigerated or shelf-stable.
- Do I need an alcohol license to sell kombucha in Ohio? 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 the Ohio Division of Liquor Control. Because unpasteurized kombucha keeps fermenting after packaging, especially without refrigeration, controlling ABV through cold storage and testing is essential to staying under the line.
