Fresh roasted coffee beans let off carbon dioxide in a "de-gassing" process. To keep beans fresh for as long as possible, they must be stored in a container which allows this carbon dioxide to escape as necessary, without allowing Oxygen to get at the beans and cause them to go stale.
Just screw the Coffee Cap into place with any standard screw band (not included) onto a wide mouth mason jar(not included) and store your beans in a dark spot, like a cupboard. That's it. There are no valves to replace, maintenance, or monitoring whatsoever. It just works.
Coffee Caps provide the flexibility to store large or small quantities in jars that you already have. This reduces cost, and allows you to upcycle your jars for yet another useful purpose.
