Coffee Grinding Guide

How you grind your coffee beans is the first step
influencing the final brew. Some machines will brew better if you make
sure to grind your beans to the optimal size in the first place.

Cheaper coffee grinders don't always have coarseness settings, so you will
have to experiment a little to establish how long to let your machine
grind to achieve the right coarseness (or fineness, depending on your
point of view).

The terms can be open to interpretation (just how fine is extra fine?)
These comparisons might help you gauge your coffee grinding a little better:

  • Coarse - Very distinct particles of coffee. Like heavy-grained kosher salt. Downright chunky.
  • Medium - Gritty, like coarse sand.
  • Fine - Smoother to the touch, a little finer than granular sugar or table salt.
  • Extra fine - Finer than sugar, but not quite powdered. Grains should still be discernable to the touch.
  • Turkish - Powdered, like flour. Most inexpensive (blade) grinders will be unable to grind this finely.

The table below will tell you which grind to choose to suit your particular coffee-brewing method.
