The Perfect Sourdough Jar Design
Extra-Wide Mouth Opening
Our jars come with a wider mouth opening, making it easier to add flour, remove your starter, and use a spatula to mix.
Easy-Latch Flip Top Lid
The flip-top jar style is the standard for sourdough starter jars, and for good reason. It allows the perfect amount of airflow required to supply your expanding starter.
Removable Silicone Seal
Both jars come with a removable silicone seal which we recommend removing while using the jar for sourdough to allow for the correct airflow.
