This burr grinder is made out of stainless steel, which makes it easy to clean, more resilient than glass versions, and produces less static than plastic versions. The conical ceramic burrs don’t rust, are easy to clean and stay sharper for much longer than steel burrs. The only thing mini about this grinder is it’s size! But what really sets it apart is the speed and ease of grind due to a long steel handle that connects solidly to the grinder, and the ability to hold the grinder steadily in one hand while turning the handle with the other. Have an Aeropress and like to have fresh ground, amazing coffee when you travel? This lovely little industrial looking grinder fits perfectly inside the Aeropress tube.
