When it comes to coffee grinders, there are two main types of burrs: flat burrs and conical burrs. Both types of burrs have their own unique characteristics that can affect the taste and texture of the coffee.

Flat burrs are, as the name suggests, flat disks with sharp teeth that grind the coffee beans between them. The size of the grind can be adjusted by moving the burrs closer or further apart. Flat burrs are typically found in high-end commercial coffee grinders, as they are better at producing a consistent grind size.

Conical burrs, on the other hand, are cone-shaped and have ridges that spiral around them. Coffee beans are fed into the top of the burrs and are ground as they travel down the spiralling ridges. The size of the grind can be adjusted by moving the burrs closer or further apart. Conical burrs are often found in home coffee grinders, as they are quieter and less expensive than flat burrs.

The main difference between flat and conical burrs is in the shape of the burrs and the way they grind the coffee beans. Flat burrs are better at producing a consistent grind size, which is important for commercial coffee shops where every cup of coffee needs to taste the same. Conical burrs are better at preserving the aroma and flavour of the coffee, which is important for home coffee drinkers who want to enjoy the full range of flavours in their coffee.
