The NFC disk is made of polycarbonate and is approximately two and a half to three millimeters thick.
Besides preventing popcorning, the NFC disk regulates the flow of beans through the grinder for a more even grind, and it significantly reduces the power consumption during grinding.
The NFC disk reduces the power required for grinding, although the grinding time remains the same. The reduced power is due to the beans no longer "popcorning" and the decreased load on the grinder.
The NFC disk will be included in new Niche grinders. Separately, it will be made available to consumers at the cost of postage only; the speaker is not aiming to profit from its distribution. A specific timeline for availability was not given.
This video introduces the "niche flow control device," a simple polycarbonate disc designed to improve the coffee grinding process. The speaker explains its purpose, function, and eventual availability.
