Ceramic Burrs Vs Steel Burrs

Steel burrs disadvantages.

Ceramic burrs vs steel burrs.

Baratza rates theirs for 750 pounds of coffee but reports indicate that they may be good for up to 2500 pounds. That s not because steel is inherently better than ceramic but because of the manufacturing process surrounding them. The lifespan is about half the time per pound of coffee as the ceramics but most can be replaced. Where as you typically want a harder steel for mills you also want something corrosive resistant but often a compromise needs to be made between one of the other.

Ceramic burrs transfer less heat compared to steel ones this means that the type of burr used can affect the taste of coffee. Ceramic burr are less thermally conductive than steel this means these burrs transfer less heat than steel burrs see below on heat. Since ceramic and steel burrs have different heat conducting abilities. First off ceramic burrs run a bit cooler compared to steel burrs or in other words they don t heat up as fast or retain heat as much as their metal counterparts.

The lifespan of a burr grinder depends on its quality and the burr material. And from what i have heard from people out there. Specifically ceramic burr grinders usually last through 1 000 to 1 500 pounds of coffee.

Ceramic burrs are more brittle than steel so you could chip the ceramic burr if a very hard rock was hiding in the beans. Ceramic burrs advantages. Stainless steel burr grinders typically make it through 500 to 1 000 pounds of coffee. Steel burrs though usually stainless steel can still corrode depending on the type of steel used.

Or so the argument goes. Last twice as long as steel burrs before requiring replacement. Ceramic burrs are harder than steel and last on average about twice as long as steel burrs. As far as i know you ll usually find either ceramic or steel burrs.

Ceramic burrs are molded so in order to get a high quality ceramic burr you have to a very high quality and very expensive mold. In general ceramic burrs tend to last longer than stainless steel burrs. Heat is an important factor when it comes to coffee grinder burrs because any extra heat impacts your coffee s flavor since it burns off some oils present on the beans. I haven t noticed this myself and i m not sure the argument would even apply to hand grinding.
