AeroPress Coffee Maker Conical Burr Espresso Grinder Parts

Burr grinders are more consistent than blade grinders. This is important when it comes to coffee extraction. Thus we can see there are generally two types - conical burr coffee grinders and flat burr coffee grinders on the market. Most home grinders use conical burrs since they are cost effective.

The product you're looking at is made of 95% alumina. Alumina ceramic represents the most commonly utilized ceramic material in industry. Due to its extremely superior abrasion and chemical resistance, alumina has been widely used in makeing coffee grinder burrs.

Ceramic vs. Stainless Steel Coffee Grinder
There are two standard options about burr material, steel or ceramic. Ceramic grinding burrs are harder than steel burrs, 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 burr grinder.

Customer Questions & Answers

Q1: Conical burrs Vs. Flat burrs
The highest-quality burrs are either flat or conical.

	Flat burrs consist of two flat, ring-shaped burrs lined with grooves that break up the beans as the burrs press together.
	Conical burrs are more of a V shape, with the center burr fitting into the outer burr, both of them also lined with sharp-edged grooves that cut up the beans as they press together.

Q2: Are manual coffee grinders better than electric?
