Minnesota Says Kombucha Doesn’t Need a HACCP Plan — Here’s Why That’s Different From Every Other State

By /

MDA’s Position Is the Opposite of What You’ll Find Almost Anywhere Else

If you have read about kombucha regulation in other states, Minnesota’s official position will likely surprise you. Kombucha is a fermented tea. Although fermented foods such as yogurt and sauerkraut often require a HACCP plan in Minnesota, kombucha does not. This is because tea does not require refrigeration prior to the fermentation process being initiated.

This is a direct, published statement from the Minnesota Department of Agriculture, and it reflects a specific regulatory logic that differs from the FDA Model Food Code’s specialized process classification used by most other states for kombucha brewed in retail and food service settings. Products such as beer, wine, kombucha and sourdough bread can be made safely without added procedures. Foods that do not require refrigeration, or non-time/temperature control for safety foods, prior to the fermentation process do not need a HACCP plan. However, foods that do require refrigeration for safety or TCS classification before fermentation, such as sauerkraut, kimchi, and yogurt, will require a HACCP plan.

The distinction MDA draws is precise: it is not about what kombucha becomes after fermentation, but about what it is before fermentation begins. Tea, the base ingredient for kombucha, is not a TCS food requiring refrigeration prior to fermentation starting. Vegetables used for sauerkraut or kimchi, by contrast, can be considered differently depending on preparation, and dairy used for yogurt is unambiguously TCS before fermentation even begins. This pre-fermentation classification is what determines whether MDA requires a formal HACCP plan for the process.

What MDA Does Require for Kombucha Even Without a HACCP Plan

The absence of a mandatory HACCP plan does not mean Minnesota treats kombucha as risk-free. One concern is that during the fermentation process, kombucha produces alcohol. Kombucha is not considered an alcoholic beverage and therefore must contain less than 0.5 percent alcohol to be sold as a non-alcoholic beverage. Operators may need to have the final product evaluated to confirm the product is within the legal limits to be sold.

This is the real control point MDA expects kombucha producers to manage, and it is functionally similar to the alcohol management concern that appears in every other state’s kombucha guidance, even though Minnesota frames it as a labeling and classification question rather than a formal critical control point within a HACCP document. A Minnesota kombucha producer still needs to verify their product’s alcohol content stays below 0.5 percent ABV, whether through testing, pasteurization, or another validated approach, even though this verification does not need to be documented within a formally approved HACCP plan the way it would in most other states.

In most instances, where a HACCP plan is required for similar fermented products, the critical control point is to monitor the pH to verify it is low enough to prevent bacteria from growing. Even though kombucha specifically falls outside MDA’s HACCP requirement, the underlying pH science remains the same scientific basis any responsible kombucha producer should rely on. A kombucha that has not properly fermented to a safe pH carries genuine pathogen risk regardless of whether Minnesota requires you to document that risk in a formal plan.

How This Plays Out for Cottage Food Producers in Minnesota

Minnesota’s separate Cottage Food Law treats kombucha with notable specificity, distinct from MDA’s general HACCP guidance discussed above. Some fermented foods, such as kombucha, may be refrigerated to slow fermentation, but not for food safety reasons. Under the Cottage Food Law, foods must either have a pH of 4.6 or lower or have a water activity of 0.85 or lower.

Minnesota’s Cottage Food Law lists fermented fruit, vegetables, pickles, and sauerkraut which have an equilibrium pH value of 4.6 or lower as eligible products, with examples specifically including kombucha with alcohol content not more than one-half of one percent by volume. This is a remarkably specific and explicit allowance: Minnesota’s cottage food law names kombucha directly as an eligible product, provided it meets the pH 4.6 threshold and stays under the 0.5 percent ABV alcohol limit.

This puts Minnesota in a genuinely unusual position among the states covered in this series. Most states either explicitly prohibit kombucha from cottage food frameworks by name, or leave its status ambiguous through general TCS classification questions. Minnesota does neither: it names kombucha specifically as allowed, with explicit numeric thresholds for both pH and alcohol content that a producer can test against directly.

Minnesota cottage food producers are limited to $78,000 in sales per year, must register annually with MDA, and are required to take food safety training before registering, with producers selling more than $7,665 annually required to complete advanced food safety training through University of Minnesota Extension. Registration renews annually on April 1, and customers can place orders online, but the product must be handed off directly in person, since shipping is not currently allowed for human foods under the cottage food framework.

The Verification Standard: How a Minnesota Kombucha Producer Demonstrates Compliance

Given that kombucha qualifies as cottage food in Minnesota under specific numeric thresholds, the practical question becomes how a producer demonstrates their specific batch meets those thresholds. Sourdough starter culture and similar fermented products listed in Minnesota’s cottage food guidance are specifically noted as needing to be verified by home pH testing, establishing the expectation that fermented cottage food producers, including kombucha makers, test and verify their product’s pH rather than assuming a recipe consistently produces a safe result.

For alcohol content specifically, MDA notes that operators may need to have the final product evaluated to confirm the product is within the legal limits to be sold, which for a cottage food producer without access to commercial laboratory testing infrastructure means seeking third-party testing services to confirm alcohol content stays below 0.5 percent ABV, particularly important for unpasteurized kombucha that continues fermenting after bottling.

A Minnesota kombucha producer relying on the cottage food pathway should build both pH testing and periodic alcohol content verification into their standard production routine, even though no formal HACCP plan is mandated. The numeric thresholds Minnesota’s law establishes are real, enforceable standards, and a producer who has never actually tested their finished product against them is operating on assumption rather than verified compliance.

When Minnesota Kombucha Production Requires Full Licensing Instead

Minnesota’s accommodating treatment of kombucha within both the general HACCP framework and the cottage food law applies specifically to direct-to-consumer, home-based, or otherwise appropriately scaled production. If a business wishes to produce or dispense food or beverages onsite at a community event or farmers market, they will likely need to obtain a food license, since cottage foods cannot be produced onsite at these venues. The type of foods being produced or dispensed determines whether licensure is needed from MDA or a health department.

A food license does not have restrictions on the amount of annual sales, allows for a wide variety of foods to be sold, and allows for several types of sales including shipping food in the mail. A food license requires the use of an approved kitchen space and equipment that meets applicable regulatory requirements. A kombucha producer who exceeds the $78,000 cottage food sales cap, who wants to sell wholesale to retailers, or who wants to ship product needs to transition to this full licensing pathway, working with MDA’s Licensing Liaison to confirm the specific requirements.

For a kombucha taproom or restaurant brewing and serving on-site, this falls outside both the cottage food framework and MDA’s general food additive guidance discussed above, since on-site food service operations are typically licensed and inspected by local or county health departments under Minnesota’s food code rather than through MDA’s cottage food or general food manufacturing channels.

What Minnesota Inspectors Actually Check for Kombucha Producers

Even though kombucha does not require a formally filed HACCP plan in Minnesota, MDA retains full inspection and enforcement authority. Under Minnesota law, the MDA has the authority to enter at reasonable times any establishment where food is manufactured, processed, packed, or held, with inspection and investigation activities limited to areas of the location where food is manufactured, processed, packed, or held. Inspectors may be present at venues like farmers’ markets and community events to verify registration and that food is being sold in a manner consistent with Minnesota laws, and if cottage food is suspected or confirmed to have caused illness or injury, MDA will conduct an investigation which may include an inspection of the location where the food was produced.

This means a Minnesota kombucha producer should still maintain genuine, ongoing pH and alcohol content records, not because a formal HACCP document requires it, but because these records are exactly what an MDA inspector or investigator would expect to see if your registration is checked or if a complaint triggers a closer look at your operation. The absence of a mandatory HACCP plan format does not mean the absence of expected food safety diligence.

What Causes Minnesota Kombucha Producers to Run Into Compliance Trouble

The most common issue, somewhat counterintuitive given Minnesota’s relatively accommodating stance, is producers who interpret the absence of a HACCP plan requirement as the absence of any food safety standard at all. Minnesota’s cottage food law still requires kombucha to meet the explicit pH 4.6 and 0.5 percent ABV thresholds, and a producer who has never tested either is not actually in compliance, regardless of the lighter documentation burden.

The second issue is alcohol content verification gaps for bottled, unpasteurized product. Because Minnesota’s framework places real weight on the 0.5 percent ABV threshold as the dividing line between an allowed non-alcoholic beverage and a product that would require entirely different licensing, a producer without periodic testing or a pasteurization step is exposed to real risk if their product continues fermenting past the point of sale and exceeds the threshold while in a customer’s possession.

The third issue is scale and venue confusion, particularly producers who outgrow the $78,000 cottage food cap or who want to sell at a farmers market booth where they actively brew or dispense product on-site, not recognizing that this on-site activity moves them out of the cottage food framework and into food licensing territory regardless of their kombucha’s pH and alcohol profile otherwise meeting cottage food standards.

Bottom line

Minnesota is genuinely unusual among states in this series: MDA explicitly states that kombucha does not require a formal HACCP plan, because tea, the base ingredient, does not need refrigeration before fermentation begins, distinguishing it from fermented foods like sauerkraut, kimchi, or yogurt that do require a plan. This does not mean kombucha is unregulated. Minnesota’s cottage food law specifically names kombucha as an eligible product, provided it meets an equilibrium pH of 4.6 or lower and an alcohol content not exceeding 0.5 percent by volume, with MDA noting operators may need their final product evaluated to confirm compliance with the alcohol threshold. Cottage food kombucha producers are capped at $78,000 in annual sales, must register annually with MDA, and need food safety training, with advanced training required above $7,665 in annual sales. Producers who exceed these limits, want to sell wholesale, or want to brew and dispense kombucha on-site at a farmers market or community event need a full food license instead, working with MDA’s Licensing Liaison to determine the applicable requirements.

FAQ

  • Does Minnesota require a HACCP plan for kombucha? No, and this is unusual compared to most states. MDA’s published guidance specifically states that kombucha does not require a HACCP plan, because tea, kombucha’s base ingredient, does not require refrigeration prior to fermentation beginning. This differs from fermented foods like sauerkraut, kimchi, and yogurt, which do require a HACCP plan under Minnesota’s framework.
  • Can I sell homemade kombucha in Minnesota under the cottage food law? Yes, provided your kombucha meets specific thresholds. Minnesota’s cottage food law explicitly names kombucha as an eligible product if it has an equilibrium pH of 4.6 or lower and an alcohol content not exceeding 0.5 percent by volume. You need to register annually with MDA, complete required food safety training, and stay within the $78,000 annual sales cap.
  • Does the alcohol threshold matter for kombucha sold in Minnesota? Yes, significantly. Kombucha must contain less than 0.5 percent alcohol by volume to be sold as a non-alcoholic beverage in Minnesota. MDA notes that operators may need to have their final product evaluated to confirm it stays within this limit, particularly important for unpasteurized kombucha that continues fermenting after bottling and could exceed the threshold after the point of sale.
  • Can I brew and sell kombucha at a Minnesota farmers market booth? Not under the cottage food exemption if you are producing or dispensing the kombucha on-site at the market. Cottage foods cannot be produced onsite at a community event or farmers market; if you want to brew or actively dispense product at the venue itself, you likely need a food license rather than cottage food registration. Pre-made, packaged kombucha brought to sell at a farmers market booth, by contrast, can typically be sold under cottage food registration if it meets the pH and alcohol thresholds.
