Cozy Bread® Starter Jar Warmer

The Cozy Bread® Starter Jar Warmer provides gentle, consistent warmth to support healthy sourdough starter activity, especially in cooler kitchens. Designed specifically for starter fermentation, it is smaller than our Proofing Mat and Proofing Box while using the same proven principles: a warming mat paired with an insulated housing to help retain heat. Easy to use, clean, and store in any kitchen drawer.
