EVERY CULTURE WE MAKE IS FOOD-SAFETY TESTED.
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.

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.
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.
You’ll need flour, water, a jar to keep your starter in, and your usual baking setup. If you don’t have tools yet, our sourdough kits include them.
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.
