Glass Sourdough Starter Jar

Every sourdough baker needs a proper home for their starter, and this is the one we designed ourselves. We made a custom, straight-walled glass jar with a specially engineered lid that provides the perfect balance of ventilation and protection the starter needs to thrive. It also includes a rubber o-ring to mark pre-feed expansion levels, so bakers can see their starter rise and fall. You won’t get that with a mason jar and rubber band. At 700 ml (just shy of three cups) and 5.5"H x 4" diameter, it's sized just right for regular home feeding routines — not so big that it's unwieldy, not so small that bakers outgrow it in a month. This is one of our most popular products and pairs well with our Dry Sourdough Starter for an easy bundling or cross-sell opportunity. ★ With decades of sourdough baking knowledge behind it, we built this jar with intention. We know what works, what doesn't, and what a baker actually needs — no more, no less — to successfully maintain their sourdough culture. ★ At 700 ml (just shy of three cups) and 5.5"H x 4" diameter, it's sized just right for regular home feeding routines — not so big that it's unwieldy, not so small that bakers outgrow it in a month.protection the starter needs to thrive.
