Starting a hot sauce business is mostly about one fact: peppers are a low-acid food, so a sauce of peppers and vinegar is, in FDA's terms, an acidified food, the same rules as pickles. That means, before you sell a bottle in a store, a process authority reviews your recipe and process and sets the scheduled process, the pH and steps that keep the sauce safe; you register as a food canning establishment with FDA and file the process for each sauce and bottle size; someone who completed an approved school, such as Better Process Control School, supervises production; and you test and record the pH of every batch. A sauce kept refrigerated all the way to the customer is outside these rules, and so is an acid food with only a little low-acid ingredient that barely changes its pH, but the process authority decides that, not you. On top: a state food processing license where your state requires one, a licensed kitchen or a co-packer, labels, and insurance. Many cottage food laws leave hot sauce out, or allow it only with a tested recipe. In the example below, a founder plans a spring launch for about $4,200. Below are the steps, the rules, the example, and a free launch checklist.
The short version
- Peppers are low-acid, so pepper and vinegar sauces are acidified foods.
- A process authority reviews your recipe and sets the scheduled process.
- Register with FDA as a food canning establishment and file each sauce's process.
- Someone trained at an approved school, like Better Process Control School, supervises production.
- Test and record the pH of every batch.
- Make it in a licensed kitchen or with a co-packer; check your state's license.
- Many cottage food laws exclude hot sauce or require a tested recipe.
- TaroStack records each batch's pH on the batch, with its lots. More below.
The steps
| Step | What it means |
|---|---|
| Recipe | Weighed to the gram, with the finished pH you're aiming for |
| Process authority | Reviews the recipe and process and gives you the scheduled process in writing |
| Training | An approved school for whoever supervises production |
| Kitchen | A licensed kitchen you rent, your own, or a co-packer that handles the filings |
| Licenses | Your state's food processing license or registration, and FDA facility registration |
| FDA filings | FCE registration, then a process filing for each sauce and bottle size |
| Labels | Name, net contents, ingredients, allergens, your name and address |
| Records | pH and the scheduled process steps for every batch, kept with the lot code |
The filings in detail are in FCE registration, the school in Better Process Control School, the letter in process authority letter, and pH logs in pH testing for acidified foods.
The rules
| Rule | Where |
|---|---|
| What's acidified | Low-acid foods, peppers among them, with acid added; water activity above 0.85; finished equilibrium pH 4.6 or below (21 CFR 114.3) |
| What's not | Refrigerated foods; acid foods, including condiment sauces, with small amounts of low-acid food that barely change the pH (114.3) |
| Registration and filing | Register with FDA and file a scheduled process for each product and container size (21 CFR 108.25) |
| Supervision | Operations supervised by someone who completed an approved school (114.10) |
This is general information, not legal advice; your process authority and state set the details.
An example: a spring launch
Sandia Smoke Hot Sauce, a made-up hot sauce startup in Albuquerque, New Mexico, I use in these examples, plans to sell its first bottles at a spring market on March 6 and rents time in a licensed shared kitchen. Its checklist, counted back from the first sale:
| Step | Weeks before | Cost |
|---|---|---|
| Recipe final | 16 | |
| Process authority review and pH test | 14 | $300 |
| Better Process Control School | 12 | $450 |
| State food processing license | 10 | $150 |
| FDA facility registration, FCE registration and process filing | 8 | free |
| pH meter, buffers and log | 6 | $180 |
| Labels | 6 | $650 |
| Bottles, caps and shrink bands | 6 | $950 |
| Product liability insurance | 4 | $900 |
| First production run | 1 | $600 |
| Total to start, before kitchen rent | $4,180 |
The founder's first recipe came back from the process authority at pH 4.3 with a minimum hold time before bottling, and the smoked chile version needed more vinegar to stay under the line, which changed its flavor enough to rework. That's why the process review sits 14 weeks out, not two. The co-packer route would skip the school and the filings, at a minimum run of a few thousand bottles; that comparison is in sauce co-packer, and the startup budget in sauce business startup cost.
Get the checklist
Download the hot sauce launch checklist. One sheet: type your first sale date, and each step's due date counts back from it, with the cost and the date done; the status shows on time, late, to do or overdue, and the total to start adds up. It's an ordinary Excel file with no macros, and it works in Google Sheets, LibreOffice and Numbers.
Where this stops working
The checklist gets you to the first bottle. After that, every batch needs its pH recorded with its lot, and when a store asks which batch a bottle came from, the answer has to be on paper you can find.
How TaroStack does it
TaroStack keeps each batch's readings and lots together, so the records an acidified food needs sit with the sauce.
Your own fields on the batch record. Each batch record can carry fields of your own, such as the finished pH and the hold time, recorded on a phone at the kettle, with sign-off.
Lots from peppers to bottles. Each batch records the pepper and vinegar lots it used and gets a lot code of its own for the bottles.
Where it went. Each store's order records the lots it got, so if a batch has to come back, one recall report shows every store it reached.
| The job | Binder | In TaroStack |
|---|---|---|
| pH for a batch | A paper log | A field on the batch record |
| Which peppers went in | Not recorded | Lots on the batch |
| The lot code on the bottles | Hand-written | The batch's lot |
| Which stores got a batch | Invoices | One recall report |
Recipes, batches with your own fields, lots and recalls are on every plan, from $49 a month. The first 30 days are free, with no credit card. If you'd like a hand setting up, ask, and we'll do it with you.
