Crown cap with standard dimensions, equiped with a mini valve realized to control the inner pressure inside a beer bottle and two liquidproof, permeable to C02 membranes.
Externally the cap is exactly alike the common crown cap.
It includes the valve without exceeding the average cap’s thickness. No holes, No strange things, No special bottling systems.
Caps are available in many versions, with different pressure limits, according to the different styles of beer and pressure value needs.
Compatible with the most common capping machines.
When stored in horizontal position, liquid will never get out of the bottle thanks to 2 special one-direction semi-permeable membranes and the bottle will remain always 100% sealed.
No oxydation. The right carbonation, 100% fun.
The image below shows how the kcap was in 2016.
You can see it to understand how it ideally works.
Now it’s lighter, simpler, cheaper.
