How It Works
Freshly roasted coffee beans release large amounts of CO₂ after packing.
- Internal CO₂ accumulates inside the coffee bag and raises pressure.
- The internal pressure pushes open the silicone diaphragm of the valve, gas flows out.
- When internal pressure drops, the silicone membrane resets and seals tightly.
- External oxygen & moisture cannot flow back into the bag, locking coffee aroma.
