For less than the price of a cheap blade electric coffee grinder, this fine quality hand stainless steel and conical ceramic burr grinder will grind your coffee without overheating it; creating an excess of coffee powder or leaving un-ground chunks of coffee beans. Capacity is 30 grams, which exceeds the amount of coffee required to brew the average drip coffeemaker's full carafe. Disassembles for easy cleaning, and ceramic grinding parts are replaceable.
