Sourhouse™ Starter Jar

Use these specially crafted jars with Sourhouse’s Goldie (sold separately) to keep your sourdough starter at the ideal temperature. Made of durable borosilicate glass, they’re printed with incremental dots to let you know when your starter has doubled – or tripled. Flexible silicone lids prevent contaminants from entering while releasing excess gas. The flat bottom of each jar promotes efficient warmth transfer.
