Hario CMHN-4 Review, “Canister” Ceramic Manual Grinder

Hario CMHN-4 Review

Hario is popular for making coffee-preparation utensils. This Japan-based company has produced a wide catalogue of products such as drip kettles, brew coffee pots, and ceramic coffee mills such as the Hario “Canister” Ceramic Coffee Mill (CMHN-4).

The Hario CMHN-4 makes 120g, it comes in a copper color so it looks like an old-fashioned coffee mill, and it’s imported from Japan. In this Hario CMHN-4 review, we examine this coffee mill and tell you if it’s worth it. Our recommendation is based on consumer feedback given on a popular online retailer.

What You Should Know About the Hario CMHN-4

Is this manual grinder heavy?

This weighs 2 pounds. It’s very lightweight, and it either stores away easily or it sits nicely on your countertop. Note that because it has an “antique” look, it can also serve as a cute decor.

Unlike other older version, the Hario CMHN-4 doesn’t have a slip rubber cover at the bottom. It should’ve been nice to have one because it’s not permanent anyway. When you want to use it, you put it on.

It can make 120 grams of ground coffee, which is perfect for single household.

This is mostly made of glass and metal. The only plastic part is the top of the cup. The lid gasket is also made of rubber.

It comes with an adjustable hand crank. This is done to give you a huge range of brewing methods.
