Understanding the difference between a conical burr grinder and a flat burr grinder
When it comes to coffee grinders, there are two main types: conical burr grinders and flat burr grinders. While they may look similar on the outside, there are some crucial differences between the two that make each grinder unique.
The basics of burr grinders
Before we dive into the differences between conical and flat burr grinders, it’s important to understand the basics of burr grinders. Burr grinders are designed to grind coffee beans into uniform particles, which is essential for a flavorful and balanced cup of coffee. The two types of burrs, conical and flat, are responsible for crushing the coffee beans and producing the particles.
Conical burr grinders vs. flat burr grinders: what’s the difference?
So, what’s the difference between a conical burr grinder and a flat burr grinder? The main difference lies in the shape of the burrs. Conical burrs are shaped like a cone, while flat burrs are, well, flat. But what does that mean for your coffee?
The benefits of conical burr grinders
Conical burr grinders are known for producing a wide range of particle sizes, which is useful for different brewing methods. They typically have a slower RPM (rotation per minute) than flat burr grinders, which means they generate less heat and friction. This slower grind speed also results in a quieter operation. Additionally, conical burr grinders are generally less expensive than flat burr grinders.
The benefits of flat burr grinders
On the other hand, flat burr grinders produce a more consistent particle size than conical burr grinders, which is essential for espresso. They typically operate at a higher RPM, which means they can generate more heat and friction. However, many flat burr grinders have built-in cooling systems to counteract this. Flat burr grinders also tend to be more expensive than conical burr grinders, but they are a worthwhile investment for serious espresso drinkers.
