Sourdough Starter Jar

If you’ve ever tried keeping a sourdough starter alive on the kitchen bench, you’ll know how important the right jar can be. This glass starter jar is the perfect size for feeding, growing, and maintaining a healthy, bubbly starter without mess or fuss.

With a generous 750ml capacity, there’s plenty of room for your starter to rise and breathe. The two-part lid system includes a metal plate to keep dust and bugs out, plus a loose-fitting ring that allows natural gases to escape — helping prevent pressure build-up while still protecting your starter.

To make things even easier, the jar comes with a temperature indicator sticker so you can see at a glance whether your starter is sitting in a good spot in your kitchen. Keeping your starter warm enough makes a huge difference to how active it becomes, especially in cooler months.

Made from strong, food-grade glass, this jar is sturdy, easy to clean, and looks great sitting on your bench. And when you’re not using it for sourdough, it’s just as handy for storing dry goods, preserves, or pantry staples.

Please note: This product is for the jar only.
Dried sourdough starter flakes are sold separately.

Perfect for beginners and experienced bakers alike, this jar takes the guesswork out of keeping your starter happy — so you can focus on baking beautiful homemade bread.
