The " white roasted beans " are very, very hard. I was warned before hand that they would probably destroy my expensive burr grinder. He was right, in less than 5 seconds, the drive gear was toothless. I`m not sure if a hand cranked grinder would hold up. Probably will if the gears that drive the burrs are made of metal. The burrs should be able to handle the hard beans.
