How Beverages Are Evaluated Under Minnesota Law
Minnesota's cottage food law doesn't carve out a special category for beverages — they are evaluated by the same non-potentially hazardous (NPH) standard as any other product. The question is always the same: does this beverage have a pH of 4.6 or lower, or a water activity of 0.85 or lower, and can it be safely stored at room temperature?
Most beverages are water-based, which means they inherently have a high water activity (near 1.0). That rules out the water-activity pathway for almost every drink. That leaves acidity — pH ≤ 4.6 — as the primary qualifying criterion for any liquid product sold under the cottage food exemption in Minnesota.
Minnesota Beverage Status at a Glance
| Beverage | Status | Key Requirement |
|---|---|---|
| Kombucha (properly fermented) | ⚠ Conditional | pH ≤ 4.6 required; must test each batch; refrigeration for quality OK, not required for safety |
| Drinking vinegar / shrub | ⚠ Conditional | pH must be ≤ 4.6 (vinegar base usually qualifies); verify and test |
| Dry herbal tea blends | ✓ Allowed | Completely dry; no moisture; clearly a shelf-stable dry mix. No testing needed. |
| Dry hot cocoa or chai mix | ✓ Allowed | Completely dry mix. No testing needed. Follows dry mix rules. |
| Apple cider vinegar (home-produced) | ⚠ Conditional | Typically pH 2–3; verify via testing. May also require contact with MDA regarding production method. |
| Fresh-pressed juice (unpasteurized) | ✕ Not Allowed | Unpasteurized juice is a potentially hazardous food under federal and MN rules. Requires a licensed facility. |
| Pasteurized juice (home-processed) | ⚠ Conditional | Must meet pH ≤ 4.6 or aw ≤ 0.85. pH testing required. Contact MDA for guidance on specific products. |
| Water kefir / milk kefir | ✕ Not Allowed | Milk kefir contains dairy — PHF. Water kefir: pH may qualify but is borderline; contact MDA before selling. |
| Alcoholic beverages (beer, wine, spirits) | ✕ Never Allowed | Alcohol production requires separate state and federal licensing entirely outside cottage food law. |
| Dairy-based drinks (lassi, milk, smoothies) | ✕ Not Allowed | Dairy-based beverages are potentially hazardous foods. Not permitted under cottage food exemption. |
| Cold brew coffee / bottled coffee drinks | ✕ Not Allowed | Cold brew coffee has pH ~5–6 and requires refrigeration. Does not meet NPH standard. |
| Infused water / flavored water | ✕ Not Allowed | Plain water-based infusions lack the acidity or dryness to be NPH. Require refrigeration. |
| Hemp-derived beverage products | ✕ Not Allowed | MDA explicitly prohibits hemp-derived edible cannabinoid products in cottage food, including beverages. |
Kombucha — Minnesota's Most Nuanced Beverage
Kombucha is explicitly referenced in University of Minnesota Extension guidance as a product that may qualify under the cottage food exemption — but it requires testing, careful attention to the fermentation process, and a clear understanding of when refrigeration is and isn't required for safety.
- ✓Final pH ≤ 4.6 upon completion of fermentation
- ✓Product is shelf-stable at room temperature (no refrigeration needed for food safety)
- ✓Refrigeration used only to slow further fermentation (quality, not safety)
- ✓pH tested and documented for each batch
- ✓Producer registered with MDA and selling within approved channels
- ✕pH above 4.6 at time of sale
- ✕Requires refrigeration for food safety (not just quality)
- ✕Not tested — cannot demonstrate NPH status
- ✕Contains alcohol above trace levels (kombucha with secondary fermentation producing significant alcohol enters beverage alcohol licensing territory)
- ⚠Flavoring additions that raise pH above 4.6
How to Qualify Your Kombucha — Step by Step
Drinking Vinegar, Shrubs & Infused Vinegars
- ✓pH ≤ 4.6 (pure vinegars are typically pH 2–3)
- ✓Shelf-stable at room temperature
- ✓pH tested and documented
- ✓Fruit or herb infusions that don't raise pH above 4.6
- ⚠Shrubs with high fruit-to-vinegar ratios that may raise pH
- ⚠Honey or low-acid sweetener additions — test final pH
- ⚠Garlic, herb, or vegetable additions in an acidic medium — verify safety with MDA
- ✕Products that rise above pH 4.6 due to added ingredients
Dry Tea Blends, Cocoa Mixes & Drink Mixes
- ✓Dry herbal tea blends (loose leaf or bagged)
- ✓Chai spice mix (dry)
- ✓Hot cocoa mix (dry cocoa, sugar, dried milk powder if included)
- ✓Spiced cider mix (dry spices for hot apple cider)
- ✓Mulled wine spice packets (spices only — no alcohol)
- ✓Lemonade powder mix
- ✓Tisane and botanical blends
- ✓No pH testing required for completely dry mixes
- ✓The consumer prepares the drink at home by adding water, milk, or cider
- ⚠If the mix contains any liquid or semi-liquid ingredient (e.g., flavored syrup, honey), re-evaluate as a wet product
- ⚠Dried milk powder in a mix is generally fine — confirm the specific product if unsure
Juice — Federal Rules Add Complexity
- ✕Unpasteurized juice is considered a potentially hazardous food under both FDA regulations and Minnesota food safety rules
- ✕FDA's Juice HACCP rule (21 CFR Part 120) requires juice sold commercially to be processed to achieve a 5-log pathogen reduction — not achievable in a home kitchen
- ✕This applies regardless of whether the juice is high-acid (citrus, apple) or low-acid
- ✕Small farm direct sales with a warning label are sometimes discussed as an exception — these are complex, narrow FDA exemptions that do not apply to typical cottage food operations. Do not attempt without legal guidance.
Beverages That Are Never Allowed as Cottage Food
- ✕Beer, wine, spirits, hard cider, mead — all regulated by Minnesota Department of Public Safety Alcohol and Gambling Enforcement Division
- ✕Hard kombucha — once alcohol content exceeds 0.5% ABV it becomes a regulated alcoholic beverage
- ✕Alcohol-infused beverages (spirits mixed with juice, liqueur-based drinks)
- ✕Wine making for sale — requires a Minnesota winery license and federal Alcohol and Tobacco Tax and Trade Bureau (TTB) approval
- ✕Fresh dairy milk or cream beverages
- ✕Milk kefir (contains dairy — potentially hazardous food)
- ✕Lassi, drinkable yogurt
- ✕Dairy-based smoothies or protein shakes
- ⚠Hot cocoa mixes with dried milk powder (dry mix form) are fine — it's the liquid dairy beverages that are prohibited
How to Test Your Beverage Product
For any liquid or semi-liquid beverage product you plan to sell, pH testing is not optional — it's the only way to demonstrate NPH compliance when water activity is near 1.0.
