How to find a hot sauce or sauce co-packer, from 216 listed plants

This is for founders with a hot sauce, salsa, dressing, or other sauce who want a plant to make it. The short answer: first work out whether your sauce is an acidified food under the FDA rule, because that decides which plants can take it and what paperwork comes before your first run. Then shortlist plants that fill your kind of package, and send each one the same short brief. Our directory lists 216 co-packers under sauces and condiments, in 38 states, as of October 27, 2026. This guide shows what they publish about their lines and minimums, and what to ask them.

Step 1: find out which rules your sauce falls under

The FDA defines acidified foods as "low-acid foods to which acid(s) or acid food(s) are added", with a water activity above 0.85 and "a finished equilibrium pH of 4.6 or below." The rule's own list of examples includes peppers, which is why so many hot sauces land here.

The same definition leaves some sauces out. It excludes "acid foods (including such foods as standardized and nonstandardized food dressings and condiment sauces) that contain small amounts of low-acid food(s)" when the finished pH "does not significantly differ from that of the predominant acid or acid food", and it excludes "foods that are stored, distributed, and retailed under refrigeration." So a vinegar-forward sauce, a mostly pepper sauce, and a refrigerated salsa can sit under different rules even though they look alike on a shelf.

If your sauce is an acidified food, the plant carries the filing:

• It registers with the FDA on Form FDA 2541 "not later than 10 days after first so engaging" in making acidified foods.
• It files the scheduled process "for each acidified food in each container size", within 60 days of registration "and before packing any new product."
• The scheduled process includes "control of pH and other critical factors equivalent to the process established by a competent processing authority."

That last line is why co-packers ask for a process authority letter. The whole rule, step by step, is in our post on what the FDA acidified foods rule asks before your first run. Whether your recipe is acidified, acid, or neither is a call for a process authority, not for a label or a guess.

Step 2: shortlist plants that run your package

The University of Florida's extension guide to co-packers uses hot sauce as its example: "you would need a co-packer who can package liquids into small bottles. You might need to know if they can hot fill or are capable of aseptic filling." Your bottle size and fill method narrow the list faster than anything else.

Here is what the plants in our sauce category say on their own websites. Of the 216 listings, 132 have been read from the company's own website. Among those 132, the number whose processes or services name each method:

Read the table as a floor, not a census. Most plant websites do not list every process, so a plant that does not name hot fill may still run it. It is a fast way to find the plants that say so in writing, and a reason to ask everyone else directly. The Fit Check shows which listings name the product and process you enter.

Step 3: know the minimums before you call

Only 7 of the 216 sauce listings mention a minimum order on their own website. Here is each one, in the company's words, as recorded in our directory:

Two say they have no minimum and one gives no number, and the units run from cases to gallons to pallets to pounds. Turn each one into finished bottles before you compare them.

Example1,800 gallons is 230,400 fluid ounces (1,800 x 128). In 5 ounce bottles, that is 46,080 bottles per SKU, before any loss on the line. The same minimum in 12 ounce bottles is 19,200.

Our post on real co-packer minimums does this conversion for every published minimum we found, and the cost calculator turns a quote into a cost per unit.

Step 4: look where the plants are

Shipping a pallet of bottles across the country costs money, and visiting the plant before you sign is worth the trip. The states with the most sauce listings:

Of the 216, 158 are USDA organic certified and 58 are not. If you plan to sell an organic sauce, start with the certified ones, and see our guide to finding an organic co-packer for what your own brand may need. For one product at a time, our product pages list the certified co-packers whose records name it: hot sauce (10), salsa (25), salad dressing (30), pasta sauce (21), and ketchup, mustard, and mayo (70).

Step 5: send the same brief, then ask these questions

Send every plant on your shortlist the same short brief: what the sauce is, the bottle and cap you want, the size of your first run, and whether you have a process authority letter yet. The same brief to every plant gives you quotes you can compare. Our request for quote template has the fields.

Then, on the first call:

1. Are you registered with the FDA to make acidified foods, and have you filed processes for sauces like mine?
2. Do you work with a process authority, or do I bring my own letter?
3. Which bottle sizes and neck finishes run on your line today, and do you hot fill or cold fill?
4. What is your minimum per run, per SKU, in finished bottles?
5. Who buys the ingredients, bottles, caps, and labels, and who holds them between runs?
6. If I want organic, does your certificate cover a product like mine?

More questions, by stage, are in our guide to questions to ask a co-packer.

What to do next

If you would rather not email a dozen plants, get matched free: tell us what your sauce is and the package you want, and we ask the co-packers that fit. We never share your recipe.
