Day 4 — alive

Almost gave up day 2. Day 4: bubbles everywhere. The instructions are gold.

Better than live jars

Two other brands died on me. This one bubbled day 3 and never quit.

First loaf at 47

I was scared of sourdough for a decade. This made me a baker.

Questions, answered

The fine
print.

How long does it take to wake up?

Our dehydrated starters bubble in 5-7 days following the day-by-day guide. Live jars are ready to bake within 6-12 hours after a single feed.

How long does it stay shelf-stable?

Sealed dehydrated pouches last 12 months on a pantry shelf. The live jar should be refrigerated and fed weekly — it'll keep indefinitely once you're maintaining it.

What if my starter doesn't wake up?

Following our guide, fewer than 1% don't. If yours hasn't bubbled by day 7, send a photo through our contact form and we'll ship a fresh replacement at no cost.

Can I pause or cancel my subscription?

Yes — anytime from your account or by emailing us. No fees, no questions. Pause for any length and resume when you're ready to bake again.

Do you ship internationally?

Currently only within the United States. We're working on Canada and Mexico — sign up for the newsletter to know when it goes live.

Made with care

Two friends,
one kitchen.

We pack every packet by hand from a single jar of starter we’ve been feeding for years. No factories. No middlemen. Just two friends and the same wild yeast we use at home.

If your starter doesn’t bubble in 7 days, write to us. We’ll make it right.
