EVERY CULTURE WE MAKE IS FOOD-SAFETY TESTED.
Every culture we make in-house is food-safety tested, including your San Francisco sourdough starter. Before a single loaf, we want you to feel good about what you’re bringing into your kitchen.
Testing costs us more, and we do it anyway. Because the bread you bake is the bread you hand to the people you love.
A MOM’S REASON. OUR STANDARD SINCE 2002.
Cultures for Health was founded in 2002 by a single mom who wanted to feed her children the best food she could.
That care still shapes what we make. Food-safety testing is a meaningful investment, and one we keep making for the families who bring our cultures home.
Start something good in your kitchen →Real kitchens. Real first loaves.
Customer experiences, not a promise of identical results. Reviews refer to the starter, not a separate kit rating.
From packet to proud-of-it.
Sourdough takes a little patience, not a new personality. Here’s the path.
Add flour and water, then follow the included activation guide. Give the culture time to become active before baking.
Follow a sourdough recipe using your active starter. You bring the ingredients and oven; we bring the guide and support.
Keep some starter, feed it, and keep baking. Bread today. Pizza, pancakes, or a new favorite next.
Only buy what you need.
Already have the tools? Start small. Want a little more setup? There’s a kit for that.
I have the supplies.
Bring your own tools, jar, flour, and water.
A little help getting started.
Set up for the long run.
Current product prices. Shipping, taxes, and any eligible offers are calculated at checkout.
ONE STARTER. MORE TO MAKE.
Keep your heirloom starter fed and cared for, and keep making. Bread, pizza dough, pancakes. Your kitchen, your kind of homemade.
Explore sourdough recipes →A little reassurance goes a long way.
Something not looking right? Our on-staff fermenters are here to help. Our published 60-day culture guarantee offers replacement support if your culture gives you trouble.
Read the culture guarantee →Before you start.
You’ll receive a dehydrated starter culture. You activate it with flour and water using the included guide before baking.
Activation takes time, and the pace varies with temperature, flour, and feeding. Follow the guide and use the starter’s activity, not a fixed deadline, to know when it’s ready.
No. This is an heirloom culture. Keep a portion of your active starter and feed and maintain it according to the instructions so you can keep baking.
All options need flour, suitable water, and your baking setup. Starter Only also needs your tools and jar. The First-Loaf Kit supplies the listed tools but not a jar. The Complete Kit includes a starter jar and additional tools.
You don’t have to guess your way through it. Start with the included guide, use the troubleshooting resources, and contact our fermenters if something isn’t working. The culture guarantee has replacement support; see the policy for terms.
No. This San Francisco-style starter contains organic white wheat flour and live active cultures. It is manufactured in a facility that processes products containing gluten.
