Why This Page Exists
The Gray Zone Products
Michigan's cottage food law is based on a positive list — only explicitly approved products are permitted. But many sellers arrive with products that fall into genuine gray zones: they're not clearly listed, they resemble listed products, or the safety science seems similar enough to something that is permitted. This page addresses each of those cases directly, with the regulatory status, the food science explanation, and — where applicable — the path to selling legally if cottage food isn't the right vehicle.
The golden rule throughout: when in doubt, contact MDARD before you produce. A 5-minute email or phone call can save you from inventory you can't legally sell.
Contact MDARD's cottage food team directly for product-specific questions: MDARD-CottageFood@michigan.gov or 800-292-3939. Include your zip code so your inquiry routes to a local food inspector.
Edge Case #1
Pickles & Pickled Vegetables
🥒
✗ Prohibited
Pickles & Home-Canned Pickled Products
Cucumber pickles, pickled beets, pickled green beans, etc.
Pickles and all home-canned pickled vegetables are prohibited under Michigan cottage food law.
This is one of the most frequently misunderstood rulings in Michigan cottage food. Despite being acidic, pickles require home canning — a processing method explicitly outside the cottage food exemption. Canned goods require licensed processing regardless of their pH because the canning process itself (water bath or pressure canning at home) can introduce botulism risk when not properly controlled.
Why They're Prohibited
- Home canning is not permitted under cottage food law
- Even correctly acidified pickles require licensed processing
- Clostridium botulinum risk in improperly acidified products
- Canning equipment and technique cannot be verified in uninspected kitchen
- MDARD explicitly lists pickled products as not allowed
What You Can Sell Instead
- Dry dill pickle seasoning mix
- Pickling spice blends (dry)
- Flavored vinegars (herb-infused)
- Dried dill, coriander, mustard seed blends
- "Pickle everything" dry spice kits
The science: Botulism toxin (produced by Clostridium botulinum) is odorless and colorless — you cannot detect an unsafe jar by sight or smell. Safe water-bath canning of pickles requires pH ≤ 4.6 verified by validated testing, not just a general recipe. Without licensed processing controls, there is no way to confirm safety, which is why all home-canned goods — even acidic ones — require a licensed facility in Michigan.
Michigan ranks #1 nationally in pickling cucumber production — fueling the Vlasic operation in Imlay City. If you want to sell pickles legally, a licensed food establishment with validated processing procedures is the path. Many Michigan food incubator kitchens support pickle producers.
Edge Case #2
Hot Sauce & Pepper Sauces
🌶️
⚠ Verify with MDARD
Hot Sauce — Vinegar-Based vs. Fermented
The answer depends entirely on how the sauce is made
Hot sauce falls into a genuine gray zone that requires MDARD verification for your specific formula.
The cottage food status of hot sauce depends on its production method and final composition. Michigan's allowed list includes vinegar, and a hot sauce that is essentially a flavored vinegar — peppers steeped in or cooked with vinegar, strained, and bottled — may qualify. A fermented hot sauce does not. The key variables are the processing method, the pH, and whether the finished sauce is truly shelf-stable without refrigeration.
May Be Allowed (Verify)
- Vinegar-based hot sauce where vinegar is the primary liquid (Tabasco-style)
- Dried and ground hot pepper powder or flakes
- Dry chili seasoning blends
- Dry hot sauce seasoning packets
Definitely Prohibited
- Fermented hot sauce (lacto-fermented peppers)
- Hot sauce requiring refrigeration
- Canned hot sauce or pepper mash
- Fresh pepper sauces without vinegar preservation
- Hot pepper jelly (doesn't meet 21 CFR Part 150)
The science: A vinegar-based hot sauce with a final pH of 4.0 or below can be shelf-stable. However, the safety depends on the exact recipe, the pepper-to-vinegar ratio, and whether any low-acid ingredients dilute the acidity. Without validated pH testing, "seems acidic enough" is not a compliance standard. Contact MDARD with your specific recipe before producing and selling.
Edge Case #3
Fermented Foods — Sauerkraut, Kimchi, Tepache
🫙
✗ Prohibited
Lacto-Fermented & Cultured Foods
Sauerkraut, kimchi, fermented pickles, tepache, miso, cultured products
All lacto-fermented and cultured food products are prohibited under Michigan cottage food law.
Fermentation is a complex, live biological process. While lacto-fermented foods can be very safe when properly made, the safety depends on precise monitoring of salt concentrations, temperature, fermentation time, and pH — all variables that require documentation and controls that an uninspected home kitchen cannot provide to a regulatory standard.
Prohibited Fermented Products
- Sauerkraut (all varieties)
- Kimchi
- Fermented cucumber pickles (lacto)
- Fermented hot sauce
- Tepache & fermented fruit drinks
- Miso paste
- Fermented nut cheeses
- Natto & other fermented legumes
- Kvass & fermented grain products
What You CAN Sell
- Dry sauerkraut seasoning blends
- Dry kimchi spice mixes (gochugaru-based)
- Dry miso soup mix (commercial miso + dry additions)
- Dry fermentation starter kits (instructions + spices)
- Dried herbs used in fermentation recipes
The "sell the experience, not the product" approach: you cannot sell fermented sauerkraut, but you CAN sell a beautifully packaged dry caraway-and-dill spice blend with a recipe card for home fermenters. This satisfies customer demand while staying within the law.
Edge Case #4
Kombucha & Live-Culture Drinks
🫧
✗ Prohibited
Kombucha, Water Kefir, Jun & Similar
Any fermented, live-culture beverage
Kombucha and all live-culture fermented beverages are categorically prohibited as cottage food.
Kombucha production involves active SCOBY cultures that continue fermenting in the bottle. This creates carbonation buildup (explosion risk in sealed bottles), potential alcohol content that may vary batch to batch (triggering Michigan Liquor Control Commission oversight), and pH that must be actively monitored. There is simply no safe regulatory framework for producing commercial kombucha in an uninspected home kitchen.
Specifically Prohibited
- Kombucha (first and second ferment)
- Water kefir & dairy kefir
- Jun tea
- Ginger beer (fermented, not brewed)
- Tepache & other fermented fruit drinks
- Any bottled live-culture beverage
Legal Path to Kombucha Sales
- Licensed food establishment with documented pH controls
- May require Michigan Liquor Control Commission review if alcohol > 0.5% ABV
- Michigan has an active kombucha producer community
- Grand Rapids and Ann Arbor are hubs for craft fermented beverage producers
Many Michigan kombucha brands began as home brewers who eventually built licensed production facilities. It's a viable business path — just not one that runs through the cottage food exemption.
Edge Case #5
Freeze-Dried Foods
🧊
⚠ Conditionally Allowed
Freeze-Dried Candy, Fruits & Other Foods
The fastest-growing new cottage food category — with specific rules
Freeze-drying is allowed under Michigan cottage food law — but only for specific products, only in a commercial-grade freeze dryer, and only when completed to full dryness.
Michigan's cottage food law (as updated by PA 51 of 2025) specifically addresses freeze-drying. MDARD's official guidance states that freeze-drying of non-TCS (non-potentially hazardous) foods is allowable under the cottage food law IF the freeze-drying is conducted in a commercial freeze dryer to completion. This carves out a legitimate path for the booming freeze-dried candy category while maintaining safety guardrails.
Likely Allowed (Verify)
- Freeze-dried candy (Skittles, Starbursts, gummy varieties)
- Freeze-dried marshmallows
- Freeze-dried raw fruits (strawberries, raspberries, mango)
- Freeze-dried blueberries & Michigan cherries
- Freeze-dried ice cream (novelty)
Not Allowed Even with Freeze-Drying
- Freeze-dried pickles (canning process still applies)
- Freeze-dried salad dressings
- Freeze-dried juices
- Freeze-dried beans (require special safety processing)
- Freeze-dried meats or fish
- Cut melon or cut tomatoes
The equipment requirement: Michigan specifically requires a "commercial freeze dryer" — not a residential or consumer-grade unit. Brands like Harvest Right produce freeze dryers marketed for home use, but their classification as "commercial" vs. "residential" for regulatory purposes is not clearly defined. Contact MDARD with your specific equipment model before producing for sale.
Freeze-dried candy is one of the fastest-growing cottage food categories nationally, and Michigan sellers are well-positioned for it with the state's abundant cherry, blueberry, and fruit supply. Always verify that your specific products (especially any that could be borderline TCS) are permissible with MDARD before investing in production equipment.
Edge Case #6
Nut Butters & Seed Butters
🥜
⚠ Not on Approved List
Peanut Butter, Almond Butter, Tahini & Similar
Nut and seed-based spreads and pastes
Nut butters are not explicitly listed on MDARD's approved cottage food product list. Under Michigan's positive-list approach, this means they are presumed not allowed — but verify directly with MDARD.
The permitted products list explicitly includes roasted nuts and nut brittle. It does not include nut butters, nut pastes, or seed butters. Michigan's positive-list framework means that the absence of an item from the approved list is effectively a prohibition. There may be a safety argument that commercially processed nut butters (low moisture, high fat, no TCS concerns) are similar to allowed products, but MDARD's official position must be confirmed before selling.
What IS Clearly Allowed
- Whole roasted nuts (all varieties)
- Flavored roasted nuts
- Nut brittle and nut bark
- Granola bars containing nuts
- Trail mix with nuts
What Needs Verification
- Peanut butter (ground roasted peanuts)
- Almond butter
- Cashew butter
- Tahini (sesame seed butter)
- Sunflower seed butter
Contact MDARD at MDARD-CottageFood@michigan.gov with your specific nut butter product and production method. Ask explicitly: "Is [product name] eligible as a cottage food product under MCL 289.4102?" Getting written confirmation protects you. Also note: nut butters are a major allergen concern — peanuts and tree nuts are among the nine major federal allergens requiring declaration.
Edge Case #7
Apple Butter & Fruit Butters
🍎
✗ Prohibited
Apple Butter, Pumpkin Butter & Fruit Butters
Dense, cooked fruit spreads — not the same as fruit jam
Apple butter and other fruit butters are not permitted as Michigan cottage food products.
Fruit butters — dense, smooth, slow-cooked fruit spreads — are distinct from jam and jelly in food safety regulation. Unlike jams, which have a specific definition under 21 CFR Part 150 requiring high sugar concentration as a preservation mechanism, fruit butters are essentially low-acid fruit products that may or may not meet the pH and water activity standards required for ambient shelf stability. Additionally, selling them in sealed jars implicates the canning/processing rules that cottage food law doesn't cover.
Not Allowed
- Apple butter
- Pumpkin butter
- Peach butter
- Plum butter
- Any slow-cooked, dense fruit spread that isn't jam/jelly per 21 CFR Part 150
What's Still Allowed
- Apple jelly (meets 21 CFR Part 150)
- Apple jam
- Dry apple spice mixes
- Dried apple slices (dehydrated)
- Apple pie (shelf-stable fruit pie)
Michigan's exceptional apple harvest — third largest nationally — makes apple-based products a natural fit for cottage food. The path is through jelly, jam, pie, and dried apple products rather than apple butter. Many sellers successfully build apple-forward brand identities within these parameters.
Edge Case #8
Alcohol-Infused Baked Goods
🥃
✗ Prohibited (requires separate license)
Rum Cake, Bourbon Balls, Wine Cake & Similar
Baked goods where alcohol is a featured or significant ingredient
Baked goods containing alcohol require a Michigan Liquor Control Commission license — separate from and in addition to cottage food considerations.
Even though baking may reduce some of the alcohol content in a product, baked goods that contain alcohol as a functional ingredient — where the spirit is part of the product's identity or flavor profile — require liquor licensing in Michigan. This is a separate regulatory track from MDARD cottage food oversight and is enforced by the Michigan Liquor Control Commission (MLCC).
Specifically Prohibited as Cottage Food
- Rum cake (alcohol-soaked)
- Bourbon balls or bourbon truffles
- Wine cake or wine-glazed desserts
- Baileys-flavored baked goods
- Beer bread with significant alcohol content
- Any product where spirits are a named ingredient
Generally Fine
- Vanilla extract (standard baking amount) — the ethanol is a carrier, not a feature
- Beer bread (where the alcohol fully bakes off)
- Wine-braised fruit in a pie (if alcohol fully cooks off)
The line is whether alcohol is a feature of the product vs. an incidental cooking ingredient. A rum cake is defined by its rum soaking — that's prohibited. Cookies with a few drops of vanilla extract (which is technically alcohol) are fine. When in doubt, contact both MDARD and the Michigan Liquor Control Commission.
Edge Case #9
Honey
🍯
Separate Law
Raw & Infused Honey
Regulated under Michigan apiary laws — a completely separate framework
Honey is not a cottage food product. It is regulated under Michigan's apiary laws, which provide a separate direct-sale exemption for beekeepers.
Honey has its own regulatory home in Michigan — one that is often more permissive than cottage food for actual beekeepers. Raw honey sold directly by a Michigan beekeeper to consumers generally qualifies for a direct-sale exemption under Michigan's apiary framework. This is entirely separate from cottage food law and should not be confused with it.
What Beekeepers Can Do
- Sell raw honey directly to consumers
- Sell at farmers markets as the producer
- Sell multiple honey varietals (wildflower, clover, buckwheat)
- Michigan has abundant wildflower honey from its agricultural diversity
Verify with MDARD
- Infused honeys (hot honey, garlic honey) — may require separate review
- Creamed honey — verify processing requirements
- Honey combined with other ingredients — may trigger different rules
- Honey sold in retail stores — likely requires full food establishment license
Michigan's beekeeping community is substantial, supported by the state's agricultural diversity. Michigan wildflower honey — drawing from cherry blossoms, blueberry blooms, clover, and hundreds of other nectar sources — is among the most distinctive regional honeys in the Midwest. Contact MDARD's apiary program at 800-292-3939 for current beekeeper direct-sale exemption details.
Edge Case #10
Maple Syrup
🍁
Separate Exemption
Pure Michigan Maple Syrup
Subject to MDARD licensing exemptions — not cottage food law
Maple syrup is not a cottage food. Small-scale producers may qualify for a MDARD licensing exemption — contact MDARD for current thresholds and requirements.
Maple syrup production and direct-sale has its own regulatory framework in Michigan, separate from the cottage food law. The high sugar concentration of properly processed maple syrup (typically 66–68° Brix) makes it shelf-stable and relatively low-risk, which is why small-scale producers often qualify for regulatory exemptions. However, the rules are distinct from cottage food and require separate verification.
Michigan Maple Context
- Maple syrup production is the oldest agricultural tradition in North America
- Michigan Maple Weekend each spring draws visitors to sugarhouses
- Michigan produces maple syrup across the northern Lower Peninsula and Upper Peninsula
- Indigenous peoples of Michigan developed maple sugaring techniques
Key Questions for MDARD
- Annual volume thresholds for the small-producer exemption
- Labeling requirements for maple syrup
- Grade standards (Michigan follows USDA International Maple Syrup Institute grades)
- Whether maple-flavored non-syrup products require a food license
Contact MDARD at 800-292-3939 for current maple syrup exemption details. Do not assume that because maple syrup seems similar in character to jam or honey, it follows the same rules — it has its own regulatory path.
Edge Case #11
Dehydrated & Freeze-Dried Produce
🫐
⚠ Conditionally Allowed
Dehydrated Fruits, Vegetables & Herbs
Home dehydrated and freeze-dried produce items
Standard dehydration of non-TCS fruits and vegetables is allowed. Cut melon, cut tomatoes, and foods requiring special safety processing are not.
Michigan's cottage food law explicitly permits dehydrated vegetables and fruits as an allowed product category. The key requirements are that the final dehydrated product must be non-TCS — meaning fully dried to a water activity level where microbial growth cannot occur — and the starting ingredients must not themselves be TCS foods that require special processing for safety.
Allowed Dehydrated Products
- Dehydrated blueberries (Michigan specialty)
- Dehydrated cherries
- Dehydrated apple slices
- Dehydrated strawberries
- Dehydrated herbs (basil, mint, thyme, etc.)
- Dehydrated mushrooms (common varieties)
- Sun-dried tomatoes (fully dried, shelf-stable)
- Dehydrated banana chips
Not Allowed
- Dehydrated cut melon (TCS food)
- Dehydrated cut tomatoes (TCS in cut form)
- Jerky (meat — categorically prohibited)
- Partially dehydrated fruit that is still moist
- Dehydrated foods requiring special safety processing controls
The moisture rule: Properly dehydrated fruit should have a water activity (Aw) below 0.85, and ideally below 0.60 for long shelf life. At these levels, most pathogenic bacteria cannot grow. Over-dehydration is almost always safer than under-dehydration for cottage food purposes. Test your dried products — they should feel dry and leathery or crisp, never sticky or moist.
Edge Case #12
"Gluten-Free" Claims
🌾
⚠ Federal Rules Apply
Gluten-Free Labeling & Claims
Federal rules govern gluten-free claims — Michigan cottage food law doesn't override them
Labeling a product "gluten-free" triggers federal FDA requirements that apply regardless of your cottage food status.
The FDA's gluten-free labeling rule (21 CFR Part 101.91) defines "gluten-free" as containing fewer than 20 parts per million (ppm) of gluten. If you make a "gluten-free" claim on a cottage food label, you are responsible for ensuring the product actually meets that standard — which in an uninspected home kitchen that also handles wheat products is nearly impossible to guarantee without testing.
What the Rules Mean Practically
- You can produce and sell naturally gluten-free products (macarons, rice-based items)
- You cannot label them "gluten-free" unless you can verify <20 ppm gluten
- Cross-contamination from wheat products in the same kitchen is a real risk
- Many cottage food sellers describe products as "made without gluten-containing ingredients" — this is factual but does not carry the same regulatory meaning as "gluten-free"
Safer Alternatives
- "Made with almond flour — contains no wheat" (factual)
- "Made without gluten-containing ingredients" (descriptive)
- "Ingredients: [list all, none of which contain gluten]" (transparent)
- Simply list ingredients and let customers assess for themselves
For cottage food sellers with customers who have celiac disease or severe gluten sensitivity, the most honest and protective approach is to describe your ingredients accurately and note that your kitchen also processes wheat products. This is more helpful to a celiac customer than a potentially inaccurate "gluten-free" claim.
