Coffee Caps are BPA- and Phthalate-free silicone airlocks.
Before First Use
Pinch the tip of the Coffee Cap valve to separate the opening. This only needs to be done once before the very first use, never again.
How to Clean
Clean your Coffee Caps before each use. They are dishwasher safe.
During Bean Storage
There is no maintenance or monitoring required. Simply screw the Coffee Cap into place, and store your jar of beans in a dark, room temperature spot - like a cupboard.
Store your Coffee Caps flat in between uses. This will prevent them from losing their shape. Ensure they are dry before storing.
