One of the main ways the Niche Zero coffee grinder has been enhanced since the first generation is the Niche Flow Control Disc (or NFC Disc). This is a small, transparent disc manufactured from food-safe polycarbonate that you can place in the bean funnel. When you do this, it stops the coffee beans from jumping in the funnel before reaching the conical burr. It helps funnel the beans into the burrs at a steady speed making for better consistency of the grind. It also helps make the grinding process quicker.
