Porlex Tall Hand Coffee Grinder II burr grinder is made out of stainless steel. It’s 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. But what really sets this apart is the speed and ease of grinding. This is due to the long steel handle that connects solidly to the grinder. You can easily 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.
