Within a whole array of premium hand grinders from Timemore, you could argue that the Chestnut C range really redefined the manual grinder category. While super premium hand-grinders existed before, the Chestnut C made highly consistent grinding accessible to many more people thanks to its more affordable price tag, without skimping on the quality of the components. The Chestnut C really raised the bar on what home brewers could expect from a manual coffee grinder. That's probably why it became (and has always remained) our most popular range of hand grinders.
