Get A Free Starter Jar For A Friend

Sourdough season is upon us and it is time for a bit of sourdough generosity!

At Sourhouse, our mission is to encourage more people to bake sourdough bread...so today we are announcing that this Labor Day weekend we are giving everyone who buys a Sourhouse Starter Jar an additional free jar and an invitation.

Instead of keeping that jar to yourself, we are invite you to fill it with a bit of your sourdough starter and give it to a friend who might want to start baking.

Just put 2 jars of any size in your cart and use this code at checkout before 11:59pm ET on Monday, Sept 1st 2025 to get the 2nd jar free: GiveAJar-2025

We know some of you are probably thinking of a sweet free jar to keep in the fridge. We cannot stop you but hear us out.

If you love baking sourdough bread you probably have some extra starter. So why not give some away to launch someone’s sourdough journey? 

There is no such thing as discard…only gifts we didn’t give.

Terms:

Code only applies to Sourhouse Starter Jars (any size) sold on sourhouse.co.

Bundles are excluded from this offer.

Code (GiveAJar-2025) must be used at checkout to claim free second jar.

Discount cannot be applied to past orders.

Deal expires Monday, Sept 1st 2025 at 11:59pm ET.
