The Jar-digan, Insulated Sourdough Starter Jar Cover

Keep your sourdough starter cosy and comfortable with The Jar-digan, our snug, insulated cover designed to help keep your starter warm and at a more stable temperature while it ferments.

Sourdough starters thrive in a warm, consistent environment, and the Jar-digan helps protect your jar from draughts and sudden changes in room temperature. Simply wrap it around your starter jar to give your culture its own little insulated space, helping to create a more stable environment for feeding, fermenting and rising.

The Jar-digan has been designed with sourdough bakers in mind and is a great fit for the Kilner jars we sell. Its soft, padded construction helps hold warmth around the jar while still keeping your starter easy to access when it is time to feed.

Each Jar-digan is carefully handmade in small batches using quality fabrics, giving every one its own handcrafted character. Practical, reusable and just a little bit adorable, it gives your starter a cosy place to live between feeds.
