The hardest part of how to sell sourdough starter is not the starter itself. It is proving your jars are allowed where you live and that your price leaves something after you pay yourself. Start with the rules, then do the math.

Check your state rules before you sell a jar

Cottage food laws vary by state. According to Crumbcoach, some states require a county registration or state permit. A few may ask for a home kitchen inspection. Florida requires no license, inspection, or training at all. The same guide says each state sets an annual gross sales cap ranging from tens of thousands of dollars to $250,000 in Florida.

A 50-state guide from Crosodo lists a $100,000 cap for Maryland. That number is a ceiling on sales, not on profit. Your own state may be higher or lower, so find your state’s cottage food page and read the cap before you buy jars.

Farmers markets are one of the most commonly allowed venues under cottage food laws, the same guide says. Ask the market manager what they require, and ask your county health department whether your starter is allowed. Get the answer before you pay for a table.

If you already sell bread, use the same rule check as how to sell sourdough bread from home. The permit and cap questions do not change just because the product is a starter.

Write down three answers before you spend money: Is a starter allowed, what permit or registration applies, and what is the annual sales cap. Ask for the answer in writing or save the web page. If a county and state office give different answers, follow the stricter one and keep a note of who told you what.

Decide what you are selling and how you will label it

You are selling a starter, not a loaf of bread. Your buyer needs to know what is in the jar, how to keep it, and who made it. Ask your state or county what label text it requires. Do not copy another seller’s label and assume it is right for your state.

Pick one jar size and stay with it for your first month. A smaller jar is easier to price and easier for a new buyer to try. Write the storage instructions in plain words. If your state gives you required label wording, use it exactly.

Your label is often the first thing a buyer reads. Put your name and contact where she can find it. Keep the storage line short enough to read on a phone. If you sell at a market, tape a copy of the label to your table so buyers can check it before they pick up a jar.

Price a jar so ingredients, labor, and overhead are all paid

Start with one jar, not one batch. Add the flour and water in that jar, the jar and label, your time for feeding and drying, and a share of your overhead. Overhead includes market fees, mileage, card fees, and your phone. If your price does not cover all three, you are paying buyers to take your starter.

The cost math is the same as how to price sourdough bread, but you stop at the jar. Do not add a bread price to a starter price. They are different products with different costs.

Set a floor price before you talk to a buyer. The floor is the number that covers ingredients, labor, and overhead with nothing extra. Any price below the floor loses money. Any price above it gives you a margin you can save for jars, labels, and the next market fee.

For example, use Maryland’s $100,000 cap from the Crosodo guide as your year-end check. Sales minus ingredients minus labor minus overhead equals your margin. If sales reach $100,000 and those three lines total $100,000, your margin is $0. If they total less, the difference is your margin. The same subtraction works under Florida’s $250,000 cap, but the room is larger.

Keep records that prove you are under the cap

Your cap is based on gross sales, so every jar counts before you subtract flour or your time. Keep a simple log with the date, buyer, amount, and payment method. Add up the log each month. If you are close to the cap, stop and check your state rules before you take more orders.

Once you exceed the state’s annual sales cap, you generally need to move into a licensed commercial operation, the same guide says. That step can change your costs. Plan it before you hit the number, not after.

Use one notebook or one spreadsheet for every sale, not a mix of texts and receipts. At the end of each month, add the total and write it at the top of the page. That number is what you compare to your state cap. It also gives you a clean record if you need to show your sales.

If you want a price range for the bread you make with the starter, see how much to sell sourdough for. Keep that number separate from your starter sales so your cap math stays clean.

Mistakes that cost you money before your first sale

Before you commit to a market table or a bulk jar order, check three things: the permit, the label, and the cap. If any one is unclear, wait. A missed rule can cost you more than a slow month. A clear rule lets you price and plan with a calm head.

Take the first order without guessing

1. 1

   Check your state and county

   Find the cottage food page for your state. Ask whether a starter is allowed, what permit or registration you need, and what the annual sales cap is.

2. 2

   Confirm your starter is shelf stable

   Ask whether your starter needs refrigeration. If it does, the same guide says it is usually prohibited under cottage food law.

3. 3

   Set your label and jar size

   Choose one jar size and write the label your state requires. Include your name, contact, ingredients, and storage instructions.

4. 4

   Cost one jar

   Add ingredients, packaging, your labor, and a share of overhead for one jar. Set a price that leaves a margin after all three.

5. 5

   Record every sale

   Log the date, amount, buyer, and payment method. Add up sales each month and compare them to your state cap.

6. 6

   Move up when you hit the cap

   Once you exceed the cap, the same guide says you generally need a licensed commercial operation. Plan that step before you get there.

Your first five orders are a test, not a launch. Sell to people who will tell you the truth about the jar, the label, and the price. Write down what they ask. If three buyers ask the same question, fix the label before you sell to strangers.

Common questions

Can I sell sourdough starter from my home kitchen?

It depends on your state. Some states require a county registration or state permit, and a few may ask for a home kitchen inspection. Florida requires no license, inspection, or training at all. Ask your state and county before you sell, and get the answer in writing.

Do I need a permit to sell starter?

A permit may be required. Some states require a county registration or state permit, and a few may include a home kitchen inspection. Florida requires no license, inspection, or training at all. Ask your county health department what applies to a starter sold from your home.

What is the sales cap for sourdough starter?

Each state sets its own annual gross sales cap. According to Crumbcoach, the range runs from tens of thousands of dollars to $250,000 in Florida. A 50-state guide from Crosodo lists a $100,000 cap for Maryland. Your cap counts sales, not profit, so track every jar.

Can I sell at a farmers market?

Farmers markets are one of the most commonly allowed venues under cottage food laws. You still need to follow your state's permit, label, and sales cap rules. Ask the market manager what they require before you pay for a table.

What if my starter needs refrigeration?

Foods that need refrigeration to stay safe are usually prohibited under cottage food law, according to the same guide. If your starter is wet and must stay cold, ask your state before you sell it. A shelf stable dried starter may fit more states, but confirm it in writing.
