⚡ At a Glance
- • Fermentation Control: One-way valve releases built-up fermentation gases automatically while preventing oxygen ingress
- • Best for: Home fermenters making kefir, kimchi, sauerkraut, sourdough starters and overnight oats
- • Not ideal for: Users who need dishwasher-safe jars or frequent boiling sterilisation
A pair of 1.4 litre glass jars with airtight silicone seals and one-way air-release lids. Designed for safe, low-maintenance small-batch fermentation at home.
Hands-off gas management - with a one-way air-release valve
A valve built into the lid lets fermentation gases escape while blocking external air, eliminating the need for loose covers. Valve operation is automatic, removing manual burping or cloth coverings from the process.
Built-up gases leave the jar without letting oxygen in, so batches can ferment safely without constant checking. The approach reduces the chance of contamination and saves time.
Cleaner ferments, less mould risk - with an airtight silicone seal
A silicone gasket sits between lid and jar to create an airtight closure that prevents oxygen entering the contents. The seal keeps airborne contaminants out during active fermentation and storage.
Reduced oxygen contact lowers mould risk and keeps flavours purer, useful for delicate ferments like sourdough starters. Reliable sealing helps results stay consistent batch to batch.
Sturdy, fridge-friendly storage - with strong 1.4 litre glass construction
Thick glass construction is specified for storing fermented foods and suits both fridge and room-temperature placement. The 1.4 litre capacity accommodates generous single-batch volumes or regular household portions.
Generous capacity and robust glass make the jars practical for daily use and repeated handling. Suitable for keeping starters, kefir or chopped vegetables until ready to eat or refrigerate.
