Burr grinder

A burr grinder is a device for crushing coffee beans that works much like a large pepper mill. Instead of using spinning blades that chop the coffee into a random mix of fine dust and large chunks, burrs grind everything into particles of the exact same size. This consistency ensures that hot water pulls flavor evenly from every single piece during brewing, which is the absolute foundation of specialty coffee. By simply adjusting the distance between the two burrs, you can easily switch from a fine powder meant for espresso to a coarser grind for a V60. Many coffee professionals agree that the grinder actually plays a much bigger role in shaping the final taste of your cup than the coffee machine itself.
