Ready to fill your home with the warm aroma of homemade bread and other bakes coming out of the oven? Here you can buy sourdough starter to kickstart your journey.
Primrose, how I lovingly call my sourdough starter, is very happy and active because it is fed with the finest organic flour, following strict quality standards.
Just add flour and water and watch it come to life again and again! It will turn into a bubbly, robust starter ready to make your breads and other bakes rise naturally, with that rich flavor and beautiful texture that makes sourdough so special.

Not only I use this very same sourdough starter to bake hundreds of loaves for family, friends, neighbors and customers of my bakery, Leaf and Loaf, but I also share it with my workshop students, who immediately start baking with amazing results!

Now, I'm making it available for you to bake your own sourdough bread at home, ensuring proven, bakery-quality results.

Other sourdough sellers make bold claims about their cultures being "300-year-old", or having "verified heritage". Anyone can say anything on the Internet. I decided to do something no one else has done: I paid to have my starter professionally sequenced and lab-analyzed to identify and verify exactly what's living inside it - and confirm those organisms are thriving. I share this report with you inside your purchase confirmation email.

When you buy sourdough starter from Leaf and Loaf, you're not buying a story. You're buying the real deal: A strong, super active, well balanced sourdough starter that performs incredibly well, for both home baking and micro bakeries.

Details that matter

I take a lot of pride in how well I care for my sourdough starter, and in the careful process I follow to capture and preserve its strength, so it reaches you just as powerful as it is in my bakery.

THE INGREDIENTS MATTER

My sourdough starter is lovingly maintained with only two ingredients:

A hearty blend of high-protein, organic wheat flour that is grown in the nutrient-rich volcanic soil of the Pacific Northwest. This flour blend is rich in minerals, enzymes and microbes (the wild yeast and beneficial bacteria you will find in my sourdough starter).
Filtered water that is chlorine-free.

That's it! The sourdough starter you buy from my page contains no fillers, no additives, and absolutely no commercial yeast added.

Why this matters: Better ingredients mean a stronger, more predictable starter.

THE PROCESS MATTERS

A portion of my sourdough starter is preserved when it is at peak activity, using a low-stress drying and handling method.
The dried, feather-like flakes are immediately packaged. Unlike most dried starters in the market, mine is never turned into powder in high speed blenders that destroy the cellular composition of the delicate microorganisms.

Why this matters: I have done a lot of research along my mother, a biology teacher, to ensure we use the best process to maximize viability, so you get a strong culture that bounces back quickly at home.

THE PACKAGING MATTERS

Leaf and Loaf's sourdough starter is packaged in bags that are:

Food safe, FDA and USDA compliant.
Moisture and oxygen resistant.
Vacuum sealed above an airtight, reclosable zipper.

Why this matters: I spend more on packaging because it helps protect the starter's freshness, cellular integrity, and viability, so it arrives ready to wake up fast and ferment strong.

Buy sourdough starter today, and you will be rewarded with fresh, delicious bread and all the other bakes that make any kitchen feel like home.

And with every bake, you're joining a tradition that's been passed down for thousands of years, turning flour, water, salt, and starter into something beautiful you can share with the people you love.
