• 850ml capacity – ideal size for growing a sourdough starter or storing medium batches of preserves.
• Glass jar and lid – non-porous, odour-free, and doesn’t react with acidic foods.

For sourdough bakers

It’s the perfect starter culture container. The wide mouth makes it simple to feed and stir, while the clear glass lets you track your starter’s rise and activity at a glance. Because glass is non-porous, it won’t absorb odours or react with acidity, keeping your starter clean and healthy. And when you need to wash up, it’s fully dishwasher safe.

Benefits for Starter Cultures

• Keeps your sourdough starter in a stable, clean environment.
• Glass walls let you easily track rise, bubbles, and activity.
• Airtight option helps prevent contamination if needed, but clasps can also be left loose for airflow.
• Easy to wash thoroughly between uses, reducing the risk of mould.

Beyond sourdough

his jar is ideal for pickling, fermenting, and preserving. Use the airtight seal to lock in brines for crisp pickles, or keep jams and chutneys stored safely for months. The same jar is just as useful for everyday kitchen storage — flour, grains, coffee, or even leftovers. With its classic design, it looks good on the shelf or the table.

Benefits for Other Uses

• Perfect for pickling: airtight seal locks in brine and flavour.
• Great for jams and preserves: traditional Weck design for reliable storage.
• Works well for ferments like sauerkraut or kimchi, as glass won’t leach or stain.
• Useful for storing dry goods such as flour, grains, or coffee.
• Attractive enough to use for serving at the table.
