SourJar 30oz

SourJar 30oz — The Starter Jar Built for Sourdough Bakers

If you’ve ever used a heavy glass jar that’s hard to lift, prone to overflow, or just too big for a small feed — SourJar 30oz was made for you. Designed specifically for sourdough starter management, it’s lightweight, shatterproof, and crystal-clear so you can track every bubble and rise without opening the lid.

Why SourJar 30oz?

• Right-sized for sourdough starters — 30oz capacity is ideal for regular feeding. Enough room to grow without overflow, and small enough to keep discard minimal. No more feeding more flour than you need to.
• Watch your starter without opening the jar — Crystal-clear Tritan lets you see bubbles forming, track the rise, and know exactly when your starter hits peak — all without disturbing it.
• Breathable PP lid — Allows gentle airflow so your starter ferments steadily and naturally. No need to crack the lid or worry about pressure buildup.
• Lightweight and shatterproof — Unlike glass jars, Tritan won’t break if it slips. Light enough to handle daily without thinking twice.
• Compact footprint — Fits neatly on any counter or shelf. Easy to store multiples side by side if you’re maintaining more than one culture.
• Dishwasher safe & BPA-free — Easy to clean after every feed. Safe for daily contact with your living starter culture.

Whether you’re just starting your sourdough journey or looking for a better way to manage an established starter, SourJar 30oz keeps your culture healthy, visible, and ready to bake with.
