Want better tasting coffee

Basic Grinder adjustment.

Adjusting your grinder maybe the key:

It may sound daunting but once you get to grips with how coffee beans behave its fairly straight forward.

How does your espresso taste?

Sour: This is often when the coffee is under extracted (extracted too fast) and it will be watery and weak.

Bitter and burnt: You are over extracting the coffee (extracting too slow).

Getting the right taste:

As a general guide a single shot of espresso should be approx 30ml in volume and should take around 30 seconds.

  • If your coffee extracts too quickly the grind is too course and needs to be finer.
  • If your coffee extracts to slow the grind is too fine and and needs to be courser.

Practice will make perfect, it’s not as difficult as you may think. Most grinders you can turn clockwise to make the grind finer, although there should be a “+” and “-” signs for you to follow.

Remember just one click at a time before testing.


  • Purchasing quality beans will ensure they are consistently roasted and give you less reason to adjust your grinder.
  • Grinder burrs will wear down overtime so ensure they are checked and changed when necessary.
  • Try to keep the same amount of beans in your hopper at all times (consistency of weight) rather than letting the hopper run dry.
  • Regular staff training will remove any fears your baristas have for learning more about getting the best from those little beans.
