There are two standard options about burr material, steel or ceramic. Ceramic burrs are harder than steel, so they last longer before they need to be replaced. Compared to steel burrs, ceramic burrs produce cup flavors that are more complex. The flavors certainly have more mouth and body feel. Thus a ceramic burr grinder is a better choice for espresso grounds compared to a steel grinder.
The product you're looking at is made of 95% alumina. It has no plating, no heavy metals, no rust, strong corrosion resistance, and can evenly extract coffee oil when the beans are precisely being grinded. In contrast, steel burrs can alter the expected flavor of the coffee by generating heat.
Besides, grinders with ceramic burrs are relatively quieter during grinding.
Ceramic Burr | Stainless Steel Burr | |
PROS | Burrs stay sharp longer Best for espresso roasts Longer lifespan (less warping, blunting) Full-body taste and mouthfeel |
Burrs start sharper Good for single-source, non-espresso beans Less initial cost Clean taste and mouthfeel |
CONS | More initial cost Break more easily |
More recurring cost Not great for warmer environments |
Q1: Conical burrs or flat burrs, how to choose?
We can't simply say who is good and who is bad when it comes to conical or flat grinding.
If you are serious about grinding consistency or you are more into finer grounds, then you should go for the flat burr grinder. However, if you are more of a medium to coarse ground kind of coffee lover, then you can stick to the conical type.
Blade | Conical Burr | Flat Burr |
Cheap Messy Inconsistent grind |
Quieter More consistent grind Good for home use and espresso |
More expensive Remarkably even particle size Best for commercial use |
