How Tennessee Divides Oversight Between TDA, TDH, and Your Local Health Department
Kombucha producers in Tennessee answer to different agencies depending on exactly how and where they sell their product, and getting this distinction right at the outset shapes everything downstream. The Tennessee Department of Agriculture’s Food Safety Section administers state laws and regulations for retail food stores and manufacturing firms processing and storing food products, and this is the agency that licenses commercial kombucha manufacturers selling packaged product for wholesale or retail distribution. If you instead operate a taproom, café, or restaurant brewing and serving kombucha directly to customers on premises, you fall under a different authority entirely: the Department of Agriculture does not license or inspect restaurants, which are under the jurisdiction of the Tennessee Department of Health, working through local health departments.
This split matters in practice. A commercial kombucha producer bottling product for grocery store distribution submits a Food Manufacturing application to TDA, while a kombucha taproom serving fresh-poured product to walk-in customers works with TDH or the relevant county health department instead, generally following the FDA Model Food Code framework that applies to retail food service operations statewide.
For TDA-licensed manufacturers, the requirement is direct: all manufacturers are required to obtain a license in accordance with the Tennessee Food, Drug and Cosmetic Act and Chapter 0080-04-13. A food manufacturing facility is defined broadly as any non-residential building, kitchen, warehouse, or establishment where food is manufactured, processed, packed, held, or transported for commercial distribution. Before construction or remodeling begins, plans and specifications must be submitted to TDA’s Consumer and Industry Services division for review and approval, meaning you need TDA sign-off on your facility layout before you build out your fermentation and bottling space, not after.
Why Tennessee’s Cottage Food Exemption Does Not Cover Most Commercial Kombucha
Tennessee operates one of the more expansive home-based food production laws in the country, and many new kombucha entrepreneurs assume it covers their operation when it generally does not. The Tennessee Food Freedom Act, also known as the Cottage Food Law, allows foods produced in a home-based kitchen to be exempt from all licensing, permitting, inspecting, packaging, and labeling laws of the state, with the narrow exception of TDH investigation during a reported foodborne illness. TDA explicitly states it does not issue permits, licenses, or conduct inspections for products made under this law.
The practical question for kombucha producers is whether fermented beverages of this kind fall within the scope of products the Food Freedom Act was actually written to cover. Kombucha is a fermented, carbonated beverage with an evolving pH and, depending on production method and storage, the potential for in-process alcohol development, characteristics that place it closer to the category of foods state cottage food laws nationally tend to exclude due to genuine food safety complexity, rather than the simple baked goods and shelf-stable jams these laws typically address. Tennessee’s law is broader than most states’, but kombucha producers should not assume coverage without direct confirmation; TDA notes it is happy to discuss food safety information but cannot render advice to firms about their specific product, which means the determination of whether your specific kombucha operation qualifies needs to come from a direct conversation with the Department rather than an assumption based on the law’s general home-kitchen language.
If your kombucha operation does not qualify under the Food Freedom Act, whether due to scale, distribution method, or the nature of the product itself, you fall under standard TDA manufacturing licensing, which requires a complete application package: the online Food Manufacturing application, all documentation listed in the Application Checklist for All Manufacturers, proof of registration with the Tennessee Department of Revenue or a local business license, water approval documentation if your facility does not use an approved municipal water source, flow diagrams of your proposed processes, and scaled facility plans showing equipment, sinks, drains, plumbing, and electrical layout.
Why Kombucha Triggers Specialized Process Requirements Regardless of Which Agency Oversees You
Whether you end up under TDA manufacturing licensing or TDH retail food service oversight, the underlying food science classification of kombucha as a fermented beverage carries specific regulatory weight. As a fermented beverage, kombucha is categorized in the FDA Model Food Code as a specialized process, and a retail or food service operator producing kombucha needs to request a variance from their regulatory authority along with submitting a food safety plan for approval before commencing operations. Tennessee’s retail food service framework follows this Model Food Code structure, meaning a kombucha taproom under TDH or local health department oversight should expect to go through this variance and HACCP plan process rather than treating kombucha brewing as routine beverage service.
The reason fermentation triggers this elevated scrutiny comes down to the chemistry involved and how unpredictable it can be without careful control. Of the steps in kombucha production, the fermentation stage in which pH drops to a target range is the step most critical for preventing acid-resistant pathogens, and producers need a validated process demonstrating they reliably achieve this target, batch after batch, rather than assuming the natural fermentation process will always behave the same way. Kombucha brewed without proper documentation and validation, even using a recipe that has worked informally for months, does not satisfy the regulatory expectation of a demonstrated, controlled process.
There is also a federal layer relevant to any Tennessee kombucha producer regardless of state-level licensing path: the alcohol content threshold enforced by the Alcohol and Tobacco Tax and Trade Bureau (TTB). Kombucha that reaches 0.5 percent alcohol by volume at any point during production, bottling, or after bottling on a retail shelf is classified as an alcohol beverage subject to TTB regulation, even if the finished product tests below that threshold at the time of initial sale. Unpasteurized, bottled kombucha continues fermenting after sealing, and Tennessee producers selling bottled product into grocery or retail distribution need an active strategy, whether pasteurization, refrigerated cold-chain management, or another validated control, for keeping the product reliably under this threshold throughout its shelf life.
The Critical Control Points a Tennessee Kombucha HACCP Plan Should Address
Regardless of which Tennessee agency has jurisdiction over your specific operation, the core food safety science governing kombucha production translates into the same handful of critical control points.
The primary CCP is fermentation pH. Kombucha typically reaches a pH range in the low 2s to high 3s once fully fermented, and the critical safety threshold most commonly referenced in HACCP-based guidance for kombucha is achieving a pH of 4.2 or below, the point at which mold-forming organisms and acid-resistant bacteria are reliably inhibited. Every batch needs documented pH testing using a calibrated meter, with the result logged before the batch moves to bottling or service, and a defined corrective action for any batch that has not reached target pH within the expected fermentation window.
The second CCP is alcohol content monitoring, particularly critical for any Tennessee producer bottling unpasteurized kombucha for off-premises sale. Because closed containers allow continued yeast fermentation while carbon dioxide buildup can actually inhibit the conversion of alcohol back to acetic acid, alcohol levels in sealed bottles can rise after the product leaves your facility. Your HACCP plan needs a documented strategy addressing this, whether through pasteurization, refrigerated distribution with documented temperature control, or another validated approach demonstrated to keep alcohol reliably below the federal threshold throughout the product’s shelf life.
The third CCP, specific to fermented beverages relying on a living culture, is SCOBY health and sourcing integrity. A contaminated or compromised SCOBY introduces unpredictable fermentation outcomes and genuine contamination risk. Your plan should include visual inspection criteria applied before each new batch, documented criteria for when a culture must be discarded rather than reused, and sourcing records for any replacement culture brought into your operation.
A fourth control point is batch identity and time tracking through the entire process, from initial brewing through fermentation, flavoring if applicable, bottling, and distribution. Every batch needs traceable identification allowing you to connect a specific bottle on a store shelf back to its fermentation records, its pH testing history, and its production date, since this traceability is what allows a fast, targeted response if any issue is later identified with a specific batch.
Maintaining Compliance as a Tennessee Kombucha Producer Over Time
For TDA-licensed manufacturers, any change to the information or contents of your original application must be submitted in writing to the Department within 30 days after the change takes place. This means a recipe modification, a change in your fermentation vessel or equipment, a new SCOBY source, or a change in your bottling or pasteurization method all require formal notification, not just an internal recipe card update.
License renewal for TDA-licensed manufacturers occurs annually, with licenses expiring June 30 each year, and failure to remit renewal payment by July 15 of the licensure year triggers a 50 percent late penalty on top of the standard fee. Building this renewal deadline into your operational calendar, rather than waiting for a reminder, avoids an entirely avoidable financial penalty layered on top of your normal compliance obligations.
If your kombucha operation grows from a small taproom pour program into wholesale bottled distribution, this transition moves you from TDH or local health department oversight into TDA manufacturing licensing territory, a meaningfully different regulatory relationship with its own application, facility plan review, and inspection process. Planning for this transition before your first wholesale order ships, rather than scrambling afterward, prevents a gap where your distributed product is technically operating without the appropriate license.
What Causes Tennessee Kombucha Operations to Run Into Compliance Trouble
The most consequential and avoidable issue is assuming Food Freedom Act coverage applies to a kombucha operation without confirming this directly with TDA. Given the law’s broad general language alongside the genuine food safety complexity fermented beverages carry, producers who proceed under an assumed cottage food exemption risk discovering, often after building meaningful sales volume, that their operation actually required a manufacturing license from the start.
The second common issue is inadequate pH and fermentation documentation, particularly among producers who developed their process informally before scaling into commercial sale. A kombucha brewer who has made a successful product for personal use or small farmers market sales for years, relying on taste and visual cues rather than documented pH testing, faces a real gap when transitioning to licensed commercial production, where TDA or TDH inspectors expect to see calibrated, logged pH data demonstrating consistent process control rather than an experienced palate.
The third recurring issue is inadequate alcohol content control for bottled, unpasteurized product entering wholesale distribution. A producer whose kombucha tests safely under 0.5 percent ABV at the point of bottling, but who has no documented strategy for what happens to that alcohol level as the sealed bottle continues fermenting on a retailer’s shelf over subsequent weeks, is exposed to federal TTB enforcement risk that exists entirely independent of Tennessee’s own state licensing compliance. This is precisely the kind of gap that surfaces not during a routine state inspection but when a federal marketplace sample comes back over threshold.

Bottom line
Tennessee kombucha producers fall under one of two distinct regulatory paths depending on their operation: TDA manufacturing licensing for bottled product entering retail or wholesale distribution, or TDH and local health department oversight for taproom and food service operations brewing and serving on premises. The Tennessee Food Freedom Act’s broad home-kitchen exemption should not be assumed to cover commercial kombucha without direct confirmation from TDA, given the genuine food safety complexity fermentation introduces. Regardless of which agency has jurisdiction, kombucha is classified as a specialized fermentation process requiring documented control over fermentation pH, targeting 4.2 or below, alcohol content management to stay reliably under the federal 0.5 percent ABV threshold throughout shelf life, SCOBY health and sourcing, and full batch traceability. TDA-licensed manufacturers must report any process or recipe changes within 30 days and renew licensing annually by June 30.
FAQ
- Can I make and sell kombucha in Tennessee under the Food Freedom Act? This is not guaranteed and should be confirmed directly with TDA before relying on it. While Tennessee’s Food Freedom Act is broader than many states’ cottage food laws, kombucha’s status as a fermented beverage with evolving pH and potential in-process alcohol development places it in a category of genuine food safety complexity that many cottage food exemptions nationally are written to exclude. TDA can discuss general food safety information but does not provide product-specific business advice, so a direct conversation about your specific kombucha operation is the appropriate path before assuming exemption coverage.
- Does Tennessee require a HACCP plan for kombucha? If you are operating as a retail or food service establishment brewing kombucha on-site, the FDA Model Food Code framework, which Tennessee’s retail food service rules follow, classifies fermentation as a specialized process requiring a variance and an approved food safety plan before operations begin. If you are a TDA-licensed manufacturer, your facility licensing process and food safety documentation similarly need to address the specific hazards fermentation introduces.
- What pH does my kombucha need to reach in Tennessee? The critical limit most commonly referenced in HACCP-based guidance for kombucha is a pH of 4.2 or below, the threshold at which mold-forming organisms and acid-resistant pathogens are reliably inhibited. Every batch should be tested with a calibrated pH meter and the result documented before the batch moves to bottling or service.
- Do I need to worry about alcohol content in my Tennessee kombucha? Yes, particularly if you sell bottled, unpasteurized kombucha through wholesale or retail distribution. Federal TTB rules classify kombucha as an alcohol beverage if it reaches 0.5 percent alcohol by volume at any point during production, bottling, or after bottling, even on a store shelf weeks later. Sealed, unpasteurized kombucha continues fermenting after bottling, so your HACCP plan needs a documented strategy, such as pasteurization or controlled cold-chain distribution, for keeping alcohol content reliably under this threshold throughout your product’s shelf life.
