Choosing the right grind size is also one of the first and most important skills that every home barista must master. It directly affects flavor, strength, and overall success of your coffee. Whether you brew with a French press, espresso machine, or pour-over dripper, it’s all about getting the grind size right for the brewing device to unlock your coffee’s full potential.
Why Grind Size Matters
Coffee extraction depends on how the water interacts with the ground coffee. If your grind is too fine or too thick for your method, it’ll lead to under-extraction (sour, weak taste) or over-extraction (harsh, bitter taste). Hence, knowledge of grind size isn’t so much a question of taste—it’s science.
Easy Grind Size Test
Not sure if your grind is right? Test it like this:
After brewing, check the flavor. If it tastes too sour or watery, your grind may be too coarse. If it’s bitter or harsh, it may be too fine. Over time, you’ll train your palate and your eye to recognize the right texture.
Also, make sure to check your brewing time. If your pour-over is significantly longer than usual, you are probably grinding too fine. If it’s moving too fast, you are probably too coarse.
Final Thoughts
Understanding and adjusting your grind size is one of the simplest yet most effective ways to brew better coffee at home. It might take some trial and error, but with each cup, you’ll develop a better sense of control and confidence in your barista journey.
So next time you’re brewing, take a closer look at those grounds—you might be just one adjustment away from your best cup yet.
