Starting a Jam Business: Rules, Cost per Jar, Records

To start a jam business, first find out whether your state's cottage food law lets you make jam at home and sell it, because most states do allow jams and jellies made with high-acid fruit and full sugar, usually with a sales cap and only direct to customers. To sell to stores or ship further, you'll move into a licensed kitchen, often a shared commercial kitchen rented by the hour. Then get your recipe and label right (FDA's standard for anything called "jam" sets the fruit-to-sugar ratio), price every jar from its full cost including kitchen time, and keep a batch record with a lot code for every batch. Below is each step, a jar costed with real numbers, and what to record.

The short version

1. Check your state's cottage food law: what's allowed, the sales cap, where you can sell.
2. Outgrowing it means a licensed kitchen, usually rented by the hour.
3. A product called "jam" follows FDA's standard: enough fruit to sugar, and 65% soluble solids.
4. Test pH and Brix on anything unusual, and keep the readings.
5. Label it: name, net weight, ingredients, allergens, your name and address.
6. Cost every jar, including the kitchen hours, which are often the biggest line.
7. Give every batch a lot code and a batch record.
8. TaroStack keeps batches, lots and best-by dates from the first jar. More below.

Step 1: cottage food or a licensed kitchen

Every state writes its own cottage food rules, so start with your state's agriculture or health department. Hawaii's, for example, are laid out in Hawaii cottage food law. Many cottage food laws allow jam made with high-acid fruit and full sugar, and some ask for a pH test or a recipe review for pepper jelly, low-sugar jam or anything with vegetables in it.

Step 2: what makes it "jam"

If you call it jam or preserves and it's made from one of the fruits FDA lists, it follows FDA's standard of identity: at least 47 parts fruit to 55 parts sugar for fruits such as strawberry, raspberry and blueberry, or 45 to 55 for fruits such as apricot, peach and guava, cooked until the soluble solids are at least 65% (21 CFR 150.160). A refractometer reading of 65 °Brix or more tells you you're there. A low-sugar product that doesn't meet the standard needs a different name, which is why you see "fruit spread" on shelves.

Jams, jellies and preserves are excluded from FDA's acidified foods rules, which cover low-acid foods made safe by adding acid, like pickled peppers (21 CFR 114.3). Add enough peppers or onions and that can change, so test the pH of anything beyond fruit and sugar and keep the reading in the batch record.

Step 3: the label

The jar needs the product name, the net weight, the ingredients in order of weight, any major allergens, and the name and place of business of whoever made, packed or distributes it (21 CFR 101.5). Cottage food labels often need extra wording that your state sets. If a gift shop wants the jam under its own name, that's private label, covered in what is private label food.

Once you're in a licensed kitchen and selling mostly to stores rather than to the public, check whether you need to register with FDA: facilities that manufacture, process, pack or hold food register unless an exemption applies, such as the one for retail food establishments (21 CFR 1.225 and 1.226). This is general information, not legal advice; your state and your inspector have the last word.

Step 4: what a jar costs

Windward Roots, the made-up taro business I use in these examples, adds a guava jam, made in a shared kitchen rented at $25 an hour. One batch: 4.5 kg of guava pulp and 5.5 kg of sugar (45 to 55, as the standard asks for guava), with pectin and lemon juice, cooked down and filled into 37 jars of 8 oz.

The kitchen is the biggest line, more than the fruit and sugar together. Make two batches in the same three-hour slot and the kitchen line drops to $1.01 a jar, and the jar costs $4.20. At a $12 market price, a $5.22 jar leaves $6.78. At a $7.25 wholesale price to a gift shop, it leaves $2.03, a 28% margin, which is thin, and why makers who sell wholesale batch up. How to set the wholesale price is in how to price handmade items for wholesale.

Step 5: a batch record and a lot code for every batch

Every batch gets a lot code on its jars and a record of what went in. For jam, the record holds:

If a jar ever comes back with a problem, or a supplier recalls a lot of pectin, the lot code on the jar leads to this record, and the record leads to every other jar from the same batch. How to build the code is in how to create lot numbers, and a cottage food version of these records is in cottage food record keeping.

Where this stops working

At one market a week, a notebook does it. Then a gift shop takes 48 jars a month, a café wants a 12-jar case every Friday, you're making four flavors, and two people cook on different days. The batch records live in a binder at the kitchen, the sales in a notebook at the market, the best-by dates nowhere in particular. When the shop asks which batch its jars came from, or the jars from March are still in a box at home, you find out from a search through paper.

How TaroStack does it

TaroStack is built for exactly this: fruit and sugar in by the lot, made into batches, filled into jars, and sold at the market and to stores.

Every batch is recorded once and traced forever. A recipe holds the fruit, sugar, pectin and jars, scaled to the batch you make. Record the batch and TaroStack takes each ingredient from the lot you used, notes which lots went in automatically, and puts the jars into a lot with its own code and best-by date. Batch record forms print with your own checklist fields, like Brix, pH and the seal check, with initials and sign-off, so the binder fills itself in the same way every time.

The cost per jar is real. Ingredients come in at what you paid, with freight spread across the delivery, and each batch is costed from its own lots, divided by the jars that came out good, and shown against what the recipe says it should cost. So the failed seal and the dearer guava land in the jar's cost the day they happen, and margins are reported per product on what each one actually cost.

Dates take care of themselves. Oldest best-by goes first everywhere stock is picked, so the March jars go to the market before the May ones. TaroStack forecasts what will expire before it's sold and what it'll cost. Lot labels print with the lot code, the date and a barcode. And if a supplier recalls a lot, one report shows every batch it went into, every shop and customer who got those jars, and what's still on your shelves.

And the market counts too. The market stall can be a site of its own, with stock moved there and counted on a phone with no signal, sending itself when you're back. Stores and cafés are customers with their own orders, picking lists and delivery notes, and if you sell online, TaroStack connects to your Shopify store, so the jars on your website are the jars on your shelf.

Lots, best-by dates, lot labels and recalls are on every plan, from $49 a month; recipes, batch records, the cost per jar and more than one site, like a kitchen and a market stall, are on Standard at $99. 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.

Questions people also ask

Can I sell homemade jam?

In most states, yes, under a cottage food law, usually direct to customers and often with a yearly sales cap. To sell to stores or ship across state lines, you'll generally need a licensed kitchen. Check your state's rules first.

Do I need a license to sell jam?

Under a cottage food law you may need a registration or permit, or nothing at all, depending on the state. In a licensed kitchen you'll need the food manufacturing license your state requires, and possibly FDA registration.

How much does it cost to make a jar of jam?

In the example, an 8 oz jar of guava jam costs $5.22 to make in a rented kitchen: $0.61 of ingredients, $1.23 for the jar, lid and label, $1.35 of labor and $2.03 of kitchen time. Two batches in the same slot bring it to $4.20.

What pH does jam need to be?

Fruit jams are naturally acidic, typically well under pH 4.6. Many states ask for a pH test on anything beyond fruit and sugar, such as pepper jelly or low-sugar jams. Record the reading with the batch.
