Rules vary by state, change without notice, and are the layer most often described wrongly online. This page tells you how to get a correct answer rather than pretending to be one.

Why there is no single answer

Every state runs its own food processing licensing, its own inspection regime and its own cottage food program. Thresholds, permitted foods, sales channels and labeling wording all differ.

What is broadly consistent: acidified foods are generally excluded from cottage food programs, because the hazard is the reason those programs are limited. So for most vinegar-based pepper sauce, cottage food is not the route, whatever a general article says.

What is entirely federal and does not vary: facility registration, the process filing for acidified foods, and operator training.

What to ask your state

Which license applies

Describe the product precisely, not generally.

"Low acid ingredients, acidified with vinegar, target pH 3.8, shelf stable, sold at markets and to local shops." Vague questions get vague answers.

Whether cottage food covers it

Ask explicitly about acidified foods, by name.

A program that permits "sauces" may still exclude acidified ones, and the distinction is the whole question.

Where you may sell

Ask about in-person, in-state shipping, and across state lines separately.

These are often three different permissions, and an online shop depends on the last two.

What the label must say

Ask for any required state wording and its size.

This is additional to the federal elements, not instead of them, and it is a common reason for a reprint.

What to have ready

Your formulation with percentages by weight. Target and maximum pH. Where you will produce. Which channels you intend. Whether you will ship.

Ask for the answer in writing, or note the name and the date. Staff differ, rules change, and a written answer is what you show a retailer who asks.

Where the answers live

Your state department of agriculture, usually the food safety or manufactured foods division. That is the first call and it is usually short.

Your state extension food science program, which often knows the practical answer and can point at a process authority.

FDA for the federal layer, registration and the process filing.
