Frequently asked questions

What makes Organic Sourdough Starter™ different from a starter I could make myself?

You absolutely can build a sourdough starter from scratch. But you don't have to spend weeks wondering whether you're doing it right. Organic Sourdough Starter™ gives you an established culture ready for you to feed, nurture, and make your own. We take care of the beginning so you can get to the best part: baking.

Is your sourdough starter really alive?

Yes! And that's the magic of it. A sourdough starter is a living culture of naturally occurring wild yeast and beneficial bacteria. Feed it flour and water, care for it properly, and it can continue growing and baking with you for years. You aren't buying something you use once. You're starting something you can keep.

How long can I keep my starter?

With proper care, there is no predetermined expiration date on a healthy, maintained sourdough culture. Sourdough starters can be maintained for years and even passed from one baker to another. Keep feeding it, and your starter can become part of your family's baking story.

I've never made sourdough before. Is this actually beginner-friendly?

That's exactly who we designed it for. You don't need to understand hydration percentages, fermentation science, or own a kitchen full of specialty equipment before you begin. We want sourdough to feel exciting, not intimidating. Follow the care instructions, learn your starter's rhythm, and you'll be surprised by what you can create.

Is Organic Sourdough Starter™ alive even though it arrives dehydrated?

Yes! That's one of the most incredible things about sourdough.

Your starter is an established living culture that we intentionally dehydrate, placing it into a dormant state for its journey to you. Once you reconstitute it with flour and water and begin feeding it, the microorganisms become active again.

Those first bubbles are your starter waking back up, and there's something pretty amazing about watching it happen.

What makes Organic Sourdough Starter™ different?

We believe something this simple deserves exceptional ingredients.

Our starter is cultivated with organic flour and purified water before being carefully dehydrated for you.

We focus on maintaining an established, vigorous culture before dehydration so you're receiving a starter designed to return to active fermentation when properly reconstituted and cared for.

Organic flour. Purified water. An established culture. Nothing unnecessarily complicated.

Does dehydrating the starter kill it?

No. Proper dehydration puts the culture into a dormant state rather than intentionally destroying it.

That's what makes dehydrated sourdough starter so fascinating. Add flour and water, provide the right environment and continue feeding it according to the instructions, and you'll begin seeing the signs of fermentation return.

Bubbles. Rise. Aroma. Activity.

You're essentially watching your sourdough culture wake back up.

How difficult is it to reconstitute my starter?

We've designed the experience for people who may have never touched a sourdough starter before.

You'll receive instructions showing you how to rehydrate and feed your starter. It doesn't require professional baking experience or a complicated kitchen setup.

Your starter may wake up on its own schedule because temperature, flour, water and your environment affect fermentation.

Give it the right ingredients, follow the process and let the culture do what sourdough has been doing for generations.

Why does purified water matter?

A sourdough starter is a living microbial ecosystem, so we're intentional about what goes into ours.

We cultivate our starter using purified water rather than treating water as an afterthought.

Once your starter is home with you, the flour, water, temperature and feeding schedule you use all become part of its new environment. That's why we provide care instructions to help you create a great environment for your newly reconstituted starter.

Why does organic flour matter?

Because flour isn't simply food made with sourdough starter. Flour is what feeds the culture itself.

We cultivate Organic Sourdough Starter™ using organic flour because we want to be intentional about the ingredients used to establish and maintain the culture we're sending to your home.

Once you reconstitute it, you'll continue feeding it, maintaining it and eventually making it uniquely yours.

How will I know when my dehydrated starter has come back to life?

You'll start seeing the signs sourdough bakers love:

Bubbles. Expansion. A developing sourdough aroma. And increasingly predictable activity after feeding.

Don't judge your starter by one feeding. Reconstitution is a process, and every kitchen environment is a little different.

As you continue feeding it according to the instructions, you'll begin learning its rhythm. That's when a packet of dehydrated starter starts feeling like your starter.

What am I really getting when I order Organic Sourdough Starter™?

You're not getting a jar of flour and water that we mixed yesterday.

You're receiving a carefully maintained, established sourdough culture cultivated with organic flour and purified water, then intentionally dehydrated so it can make the journey from our kitchen to yours.

When it arrives, it may look quiet.

Add water. Add flour. Feed it. Give it time.

Then watch what happens.

It bubbles. It grows. It ferments. It comes back to life.

And before long, something that started in our kitchen is making bread in yours.

Organic Sourdough Starter™
Wake it up. Feed it. Make it yours.

I spent six months sourcing the most coveted starters I could find, only to realize the one I was searching for was mine to create. Two years later, she’s beautifully alive, naturally sweet, and unmistakably ours.
