Product Description
There are mainly two types of coffee grinders on the market: with flat burrs and with conical burrs. We can't simply say who is good and who is bad when it comes to conical or flat grinding.
Most professional coffee drinkers feel that flat burrs give a more consistent grind, which results in a cleaner cup. Conical burrs, on the other hand, yield more fines and produce a cup with more body feel.
The product you're looking at is made of 95% alumina, an advanced ceramic that will never rust, providing long-lasting performance.

Q1: Conical burrs Vs. flat burrs
True coffee experts will tell you that nothing grinds coffee beans better than a good burr model. There are mainly two types of coffee grinders on the market: with flat burrs or with conical burrs.
Conical burrs: Common in entry-level electric grinders and manual grinders due to their smaller sizes.
When it comes to espresso, conical burrs tend to create a grind with better mouthfeel. Because they are smaller in diameter, they are typically slower.
Flat burrs: Often used in the big, professional espresso grinders. They are fast and efficient but may need to be operated by a professional.
Q2: Are manual coffee grinders better than electric?
Q3: Can a pepper grinder be used to grind coffee beans?
No. They are similar in concept, but not in a practical way. A pepper grinder may has a conical grinding burr, which looks like a good coffee grinder, but coffee beans are about 10 times larger than a pepper corn.
Q4: How long do ceramic burrs last?
Ceramic burrs are designed to last a long time, and with proper care, they can last even longer. However, the lifespan of your ceramic burrs will ultimately depend on how often you use them and how well you take care of them.
