One of the best ways to preserve freshness of roasted coffee is by buying in wholebean and grinding on demand. The Chestnut C2 by Timemore is a brilliant compact hand grinder for home or travelling use. Weighing at approx. 450g and holding a CNC stainless steel burr set, they'll stay sharper for much longer than a budget ceramic burr set.
An easy to use dial, lets you zero the burrs and count steps to your AeroPress, V60, Moka preference.
On our testing we've found the grinder most suitable for AeroPress, pour over and other filter brewing methods plus espresso grind is capable too.
The unit body is stainless steel with a great texture for comfortable grip.
