What Vermont’s Food and Lodging Program Looks For When It Reviews Your Kombucha Operation
If you make kombucha in Vermont, the agency that regulates you is probably not the one you would guess. Meat, dairy, maple, and produce fall under the Vermont Agency of Agriculture, Food and Markets, but a fermented beverage like kombucha is regulated by the Vermont Department of Health, through its Food and Lodging Program, under the state’s Manufactured Food Rule. That distinction matters because the rules, the license, and the inspector all come from the Health Department, not from Agriculture. Getting the agency right from the start saves you from chasing the wrong paperwork.
The Food and Lodging Program can be reached at 108 Cherry Street, PO Box 70, Burlington, VT 05402, at (802) 863-7221 or (800) 439-8550, or by email at FoodLodging@vermont.gov. To process kombucha for sale and distribution to other businesses, you generally need a Food Processor License, also called a Manufactured Food Establishment license. Applications must go in at least 30 days before you plan to open, and the process includes a plan review and a product list. Once approved, you print your license and post it at your physical location.
When a Health Department inspector reviews your kombucha operation, they are checking that your facility meets the Good Manufacturing Practices in the Manufactured Food Rule, that your process reliably controls the hazards in a fermented beverage, that your pH is monitored and documented, and that your alcohol content stays under the legal threshold. Vermont’s rule is specific on the pH point: food that relies principally on pH control to prevent the growth of undesirable microorganisms must be monitored and maintained at a pH of 4.6 or below. For kombucha, that requirement sits at the center of your food safety system, and the inspector will expect to see how you meet it.
Why Kombucha Triggers a Process Authority Review and Ongoing Oversight in Vermont
Vermont’s approach to kombucha rests on a combination of its Manufactured Food Rule and a process authority requirement, and understanding how they fit together clarifies what you actually need to do.
The Manufactured Food Rule requires documentation of a Process Authority Review for low-acid canned foods, acidified foods, and, importantly, products where the Department has requested documentation that there are no biological concerns with the food production process. Kombucha is a fermented product rather than a classic acidified one, since its acid comes from fermentation rather than added acid, but that middle-ground status is exactly why the Department’s discretion matters. Vermont can request a process authority review for kombucha to confirm that your specific recipe and process reliably reach a safe pH and present no biological concerns. A Process Authority Review is a product review conducted by someone with expert knowledge of food processing, and Vermont maintains a directory of processing authorities. The University of Vermont is one resource Vermont producers use for this kind of review. Securing that review, when required, is what substantiates the critical limits in your process.
Here is a Vermont nuance that catches many small producers off guard. Vermont offers licensing exemptions for certain very small food processors and cottage food operators. But the Health Department is explicit that claiming an exemption from the licensing requirement does not exempt an establishment from compliance with the food safety and sanitation requirements in the Manufactured Food Rule, and it does not prevent a public health inspector from inspecting the establishment or investigating potential health hazards. In other words, an exemption relieves you of the license, not of the rules. Your kombucha still has to meet the pH 4.6 requirement, and an inspector can still walk in. Producers who treat an exemption as a total pass on food safety oversight are misunderstanding what the exemption does.
Plan review is another Vermont requirement worth knowing about. You must submit a plan review before any new construction or significant renovation of a food processing facility. And if a licensed establishment is sold, changes ownership, relocates, or enlarges its operation, the old license is returned and the new operator must apply for and receive a license before operating.
The alcohol threshold governs everything. 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 Vermont’s alcohol licensing through the Department of Liquor and Lottery. 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 Vermont Kombucha Process Must Monitor
Kombucha’s food safety rests on two measurable critical control points, each tied to a numeric limit that the Health Department expects to see controlled and documented. 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, and Vermont writes the pH requirement directly into its Manufactured Food Rule: acid foods relying on pH control must be maintained at a pH of 4.6 or below. A typical finished kombucha sits well below that, in the range of roughly 2.5 to 4.2. Measure it with a calibrated pH meter rather than test strips, because both your legal compliance and your safety case depend 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. 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 describing how you make kombucha safely, are expected under the Manufactured Food Rule’s Good Manufacturing Practices. Vermont inspectors treat these prerequisite documents as part of the overall system, not as optional extras.
Keeping Your Vermont Kombucha Operation Compliant Between Inspections
A Food Processor License and any process authority review are ongoing obligations, not a one-time approval. Your license must be renewed and kept current, and Vermont conducts public health inspections of food processing establishments, including those operating under a licensing exemption. Your records need to be inspection-ready at all times rather than assembled in advance of a known visit.
The discipline that matters most 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.
Recipe and process changes need attention before they are implemented, not after. 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 regulatory classification of your product can shift. A significant change can warrant a fresh process authority review and an update to your documentation on file with the Food and Lodging Program. Vermont also requires a new license application if you relocate, enlarge, or change ownership of your establishment, so plan those transitions with the Health Department rather than assuming your existing license carries over.
If you expand to selling across state lines, federal requirements come into play, including FDA facility registration under the Food Safety Modernization Act. Vermont’s guidance points producers to the FDA’s requirements for interstate commerce, so plan that expansion deliberately.
Where Vermont Kombucha Producers Most Often Run Into Trouble
The recurring compliance failures for kombucha operations in Vermont cluster around a few predictable themes, several of them specific to the state’s structure.
Assuming a licensing exemption means no oversight is the most distinctly Vermont error. An exemption relieves you of the license, but not of the Manufactured Food Rule’s food safety and sanitation requirements, and not of the possibility of inspection. A producer operating under an exemption who has not met the pH 4.6 requirement or who cannot show how they control their process is exposed the moment an inspector arrives. Treat the food safety rules as fully applicable regardless of your license status.
Contacting the wrong agency is a common early stumble. Because the Agency of Agriculture handles meat, dairy, and maple, producers sometimes route kombucha questions there. Kombucha is regulated by the Department of Health’s Food and Lodging Program, and directing your application and questions to the right agency saves time.
Skipping the process authority review when the Department requires it is a serious gap. Vermont can request a process authority review for kombucha to confirm there are no biological concerns with your process, and a process that lacks that documentation when requested does not give the Health Department the assurance it needs. Securing the review before you begin, when it applies, is foundational.
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, turning a food into an alcoholic beverage in the eyes of the TTB and Vermont’s Department of Liquor and Lottery. 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.

Bottom Line
Kombucha in Vermont is regulated by the Department of Health’s Food and Lodging Program under the Manufactured Food Rule, not by the Agency of Agriculture, and that rule requires acid foods relying on pH control to be maintained at a pH of 4.6 or below. Vermont can require a process authority review to confirm your fermented product presents no biological concerns, and it requires a Food Processor License with plan review for most operations. The distinctly Vermont trap is assuming a licensing exemption means no oversight: the food safety rules and the inspector still apply. Whatever your setup, the 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. Contact the Food and Lodging Program early, secure your process authority review when required, and keep honest per-batch records from your first production run.
FAQ
- Which Vermont agency regulates kombucha? Kombucha is regulated by the Vermont Department of Health, Food and Lodging Program, under the state’s Manufactured Food Rule, not by the Agency of Agriculture (which handles meat, dairy, and maple). You generally need a Food Processor License, also called a Manufactured Food Establishment license, and applications should go in at least 30 days before you plan to open. Contact the program at (802) 863-7221 or FoodLodging@vermont.gov.
- Can I make and sell kombucha from home in Vermont? Vermont offers licensing exemptions for certain very small food processors, but claiming an exemption does not exempt you from the food safety and sanitation requirements of the Manufactured Food Rule, and it does not prevent a public health inspector from inspecting your establishment. So even if you qualify for an exemption from licensing, your kombucha must still meet the pH 4.6 requirement and you can still be inspected. Confirm your situation with the Food and Lodging Program before selling.
- What pH does my kombucha need to reach to be safe in Vermont? Vermont’s Manufactured Food Rule requires acid foods that rely on pH control to be maintained at a pH of 4.6 or below. A typical finished kombucha sits well below that, in the range of roughly 2.5 to 4.2. Measure it with a calibrated pH meter rather than test strips, and record it for every batch. Vermont may also require a process authority review to confirm your process reliably reaches a safe pH.
- Do I need an alcohol license to sell kombucha in Vermont? 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 Vermont alcohol licensing through the Department of Liquor and Lottery. Because unpasteurized kombucha keeps fermenting after packaging, especially without refrigeration, controlling ABV through cold storage and testing is essential to staying under the line.
