WECK Sourdough Starter Jars

A beautifully simple jar for feeding, maintaining, and storing your sourdough starter.

German-made WECK jars are a favorite among sourdough bakers for good reason. Their heavy glass, wide mouth, and straight-sided, no-lip design make feeding and stirring easy while eliminating the interior shoulder found on traditional canning jars where starter can collect and dry.

Each ¾-liter WECK jar includes a glass lid, removable natural rubber gasket, and stainless steel clips, allowing the jar to easily adapt to your starter routine.

For active fermentation on the counter, simply leave the gasket and clips off and allow the glass lid to rest loosely in place, giving your starter room to breathe.

When it’s time to store your starter or discard in the refrigerator, add the gasket and secure the lid with the clips for an airtight seal.

Why bakers love WECK jars:

• Wide mouth and no interior lip for easier feeding, stirring, and cleaning
• Straight-sided glass makes it easy to monitor starter growth and activity
• ¾-liter capacity is ideal for active starters and discard
• Glass lid can rest loosely in place during active fermentation
• Removable gasket and clips allow for airtight refrigerator storage
• Durable, thick German-made glass
• Easy to transition from countertop fermentation to refrigerator storage
