Vermont's cottage food framework is built around shelf-stable products — foods safe to store and sell at room temperature. Here's exactly what that means, the science behind it, and the rules that come with it.
Under 18 V.S.A. § 4301(6), a cottage food product is food that "does not require refrigeration or time or temperature control for safety." In plain English: if your product can sit on a pantry shelf for weeks or months without growing harmful bacteria, it's shelf-stable. If it needs to stay in the fridge to be safe, it isn't — and it falls outside Vermont's cottage food exemption.
Whether a food is shelf-stable comes down to two scientific measurements: pH (acidity) and water activity (how much free water is available for bacteria to use). Vermont, like the FDA, uses these two numbers as the dividing line between cottage food and licensed food production.
The food's equilibrium pH must be 4.6 or lower. Acidic environments inhibit dangerous bacteria like Clostridium botulinum.
Water activity (aw) measures available water. Below 0.85, most pathogens can't multiply — even at room temperature.
For home-canned pickles, vegetables, fruits, and fermented foods, Vermont adds a third requirement: the recipe itself must be either approved by the National Center for Home Food Preservation or reviewed by a recognized food processing authority. You can't just experiment with grandma's pickle recipe and call it cottage food — the recipe needs documented safety credentials. UVM Extension is the most common process authority resource for Vermont sellers.
Most of Vermont's allowed cottage food list is shelf-stable by nature: yeast breads, cookies, hard candies, fudge, jams, jellies, fruit butters, dry herb and spice blends, granola, popcorn, mixed nuts, roasted coffee beans, loose-leaf tea, flavored vinegars, and dry baking mixes. The newer additions from Act 42 — fermented foods, home-canned pickles, vegetables, and fruits — qualify only when they meet the pH/water activity standard with an approved recipe.
This is the limit on how much shelf-stable cottage food you can sell in a calendar year while staying under Vermont's licensing exemption. Act 42 of 2025 tripled the cap from $10,000, and consolidated the old home bakery and cottage food tracks into a single threshold.
"Gross sales" means the total dollar amount your customers pay you — before you subtract ingredients, packaging, market fees, or anything else. Track what you charge, not what you net.
Under the cottage food exemption, all sales must be direct to the consumer — meaning the person who pays you is the person who eats the food. That ground rule shapes everything below.
Vermont doesn't inspect cottage food kitchens under the exemption, but operators are still required to comply with the food safety and sanitation rules in the Manufactured Food Rule (recently amended as the Manufactured Food Emergency Rule, effective July 1, 2025). A public health inspector retains the right to inspect at any time to investigate complaints or verify compliance.
