The Most Economical: Hario Skerton Ceramic Coffee Mill
The Hario gets the job done — it turns beans into grinds, it’s cheap and it’s portable. However, it’s not going to meet the demands of espresso lovers or high volume consumers. While it has adjustable conical ceramic burrs and is dishwasher safe, the settings are not marked. It’s as slow or fast as your ability to turn the crank. Sure, you’ll get ground coffee suitable for a French Press or drip, anywhere, anytime. You’ll also get forearms like Popeye.
