Buyer FAQs

What separates a good sourdough starter brand from a bad one?

Culture strength, plain and simple. A good brand sells a vigorous, well-maintained culture — not a dusty packet of unknown age — and backs it with clear activation instructions and a guarantee. Check for real reviews from people who actually baked with it.

Is a dehydrated starter as good as a fresh one?

Yes — and for UK buyers it is often better. Dehydrated starter is shelf-stable, sails through the post without a care, and wakes up in days with flour and water. Fresh "live" starters can arrive tired or leaking after a long journey; ours arrives at peak strength every time.

How long does delivery take to the UK?

Orders ship free and promptly from our micro-bakery, and because the starter is dehydrated, transit time does not affect quality one bit. It waits patiently for you — just rehydrate it whenever it lands and follow the included instructions.
