Kilner has been making glass preserving jars in Britain since 1842 — over 180 years of helping people store, preserve and display food without waste or plastic. The thick, clear glass and airtight seal keep contents fresher for far longer than any plastic container. Buy one and it will serve your kitchen for decades.
The Kilner 2x1L Fermentation Set contains two 1-litre glass jars with specialist fermentation lids — designed specifically for producing homemade kimchi, sauerkraut, kombucha, water kefir and lacto-fermented vegetables. The fermentation lid allows CO₂ to escape without letting oxygen in — creating the perfect anaerobic environment for healthy fermentation.
Why Ferment at Home?
- Fermented foods are among the most beneficial for gut microbiome diversity — live cultures that no supplement can replicate
- Dramatically cheaper than buying quality fermented foods — a jar of our organic cabbage and a pinch of salt produces better sauerkraut than anything commercial
- The process is genuinely simple — just vegetables, salt, water and time
- Includes specialist fermentation lid with one-way airlock
- Two 1L jars — enough to run two different ferments simultaneously
- Complete beginner-friendly kit
- Zero plastic, dishwasher-safe glass
