The fastest way to find sourdough starter locally
Your best option is to check a farmers market or specialty grocery store in your area first—many sell jars of active starter for $8 to $15. Call ahead to confirm they have it in stock, since supply changes weekly. If nothing is nearby, a local bakery that makes sourdough bread will often sell you starter directly, sometimes for free or a small donation, because they want people baking at home.
If you have no luck locally, you can order starter online from established sources like Cultures for Health, King Arthur Baking Company, or Sourdough International, which ship within 2 to 4 business days. These arrive in dried form and take 5 to 7 days to reactivate before you can bake with them. The trade-off is cost—online orders run $15 to $25 plus shipping—but they arrive ready to use once you feed them.
Key Takeaways
- Farmers markets and specialty grocery stores often stock fresh sourdough starter for $8 to $15, and you can use it the same day you bring it home.
- Local sourdough bakeries frequently give away or sell starter at a low price because they benefit when home bakers succeed.
- Dried starter shipped online costs more but works well if no local source exists, and takes about a week to wake up before baking.
- Before buying, confirm the starter is active (bubbly and rising) and ask how often it needs feeding, since neglected starter requires extra work to revive.
- A friend or family member who bakes sourdough will usually give you starter for free, since they can divide their own without losing any.
Farmers markets and local grocery stores
Farmers markets are the easiest place to start. Most markets that run year-round have at least one vendor selling sourdough starter in a jar, usually labeled with the age of the culture and feeding instructions. The starter is alive and active when you buy it, so you can feed it once and bake bread within 24 hours. Prices are typically $10 to $15 per jar.
Call the market's main number or check their vendor list online before you go—this tells you whether a starter seller will be there that week. Some vendors only show up seasonally or on certain days. Specialty grocery stores like Whole Foods, natural food co-ops, and upscale markets also stock starter in their refrigerated section, usually near the baking supplies. Ask a staff member in the bakery department if you cannot find it on the shelf.
Sourdough bakeries in your area
A bakery that bakes sourdough bread daily has starter they can spare. Walk in and ask the baker or manager directly whether they sell starter or will give you some. Many bakeries do this as a matter of course—they see it as good for the community and good for business, since home bakers often become loyal customers for specialty flours and other ingredients.
Some bakeries charge a small fee ($3 to $8) to cover the jar and their time, while others give it away. If they say no, ask whether they know anyone else locally who bakes sourdough and might share. Bakers talk to each other, and a recommendation from a professional carries weight. You might also ask if they sell dried starter or can point you to someone who does.
Online sources for dried starter
If you have exhausted local options, dried sourdough starter ships reliably and costs $15 to $25 depending on the brand and shipping. Cultures for Health sells several strains with detailed instructions for reactivation. King Arthur Baking Company offers their own starter with a recipe booklet. Sourdough International specializes in heirloom cultures from around the world if you want something specific.
Dried starter arrives dormant and requires 5 to 7 days of feeding before it is bubbly and strong enough to leaven bread. You mix the powder with water and flour, feed it daily, and watch for consistent rising and a pleasant sour smell. This is longer than using fresh starter, but the end result is identical. Shipping usually takes 2 to 4 business days, so budget 10 to 12 days total from order to first bake.
Getting starter from friends and family
If anyone you know bakes sourdough, ask them for some starter. Most bakers are happy to share because they can scoop out a portion of their own culture without harming it—they straightforward feed what remains and keep going. This is free and the starter is already active, so you can bake within a day.
When someone gives you starter, ask them three things: how old the culture is, how often they feed it, and what flour and water ratio they use. This information helps you maintain it the same way they do. If they keep it on the counter, you keep it on the counter. If they refrigerate it, you refrigerate it. Starter is forgiving, but matching their routine makes the transition smoother.
What to look for when you buy
Active starter should smell pleasantly sour and look bubbly on top, with a layer of liquid (called hooch) on the surface or just below. If the starter looks flat, gray, or smells like nail polish, it is either dormant or neglected—you can revive it, but it takes extra feeding. Ask the seller when they last fed it and whether it has been sitting for weeks.
Fresh starter from a farmers market or bakery should be fed within 24 hours of purchase. Dried starter has no expiration date if stored in a cool, dry place. Before you buy, confirm the seller can tell you the feeding schedule—if they cannot, they may not know whether the starter is truly healthy. A good seller will give you written instructions or at least tell you the ratio of starter to flour to water they use.

Frequently Asked Questions
Can I use starter the same day I buy it?
Yes, if you buy fresh starter from a farmers market, bakery, or friend. Feed it once when you get home, let it sit for 4 to 8 hours until it rises and bubbles, then use it to mix dough. Dried starter needs 5 to 7 days of daily feeding before it is strong enough to leaven bread.
What if the starter I bought looks dead or smells bad?
A flat, gray, or acetone-smelling starter is dormant but usually not ruined. Feed it daily for 3 to 5 days with fresh flour and water, and it will likely wake up. If it develops mold (fuzzy growth on top) or smells rotten, discard it and buy from a different source.
How much starter do I need to buy?
A single jar (usually 4 to 8 ounces) is enough. You only need 50 to 100 grams of starter per loaf of bread, and the culture grows when you feed it. One jar will last you indefinitely if you feed it regularly.
Is mail-order starter as good as local starter?
Yes. Dried starter from a reputable seller works just as well as fresh starter once it is reactivated. The only difference is the wait time—dried takes longer to wake up, but the final bread is identical.
Can I ask a bakery for starter even if I do not buy anything?
Yes, but buying a loaf of bread or a pastry while you are there is a kind gesture. Many bakers give starter away freely, but showing appreciation for their business makes the interaction better for both of you.
