Espresso Grind Size: The Key to an Excellent Shot

Espresso Grind Size: The Key to an Excellent Shot


When it comes to brewing the perfect cup of espresso, every detail matters. Among these, the grind size of your coffee beans is crucial. It's the make or break factor that can either elevate your espresso to a creamy and rich nirvana or leave you with a disappointing cup. This blog explores why grind size is so important and how you can master it for that excellent espresso shot.

Understanding Espresso Grind Size

Why It Matters

Espresso is a brewing method that involves passing hot water through tightly packed, finely ground coffee under high pressure. The grind size affects how water interacts with the coffee during extraction. Too fine, and your espresso may be over-extracted, tasting bitter and burnt. Too coarse, and you'll get an under-extracted shot, weak and sour.

The Ideal Grind

The perfect espresso grind should feel like fine sand. Not as powdery as flour, but finer than table salt. When pressed between fingers, it should clump slightly but break apart easily.

How to Achieve the Perfect Grind

Starting with Quality Beans

Always start with high-quality, freshly roasted beans. The age and quality of your beans will significantly influence the grind and, consequently, your espresso.

Using the Right Grinder

A burr grinder is preferred over a blade grinder. Burr grinders provide a consistent grind size, essential for a balanced extraction.

Dialing In

'Dialing in' your grinder is key. Start with a recommended setting for espresso and make a shot. Observe the extraction time and taste. Adjust finer for a slower extraction and coarser for a faster one. Aim for an extraction time of about 25-30 seconds.

Troubleshooting Common Issues


If your espresso tastes sour or weak, it's likely under-extracted. This usually means your grind is too coarse. Fine-tune your grinder to a finer setting.


Bitter and burnt tastes indicate over-extraction. In this case, your grind is probably too fine. Adjust your grinder to a coarser setting.

Consistency is Key

Consistency in your grind size ensures each shot of espresso is as close to perfection as possible. Always weigh your coffee and water, and time your shots.


Mastering your espresso grind size is a journey of trial and error, but it's essential for brewing a remarkable cup of espresso. Pay attention to the details, be patient with the process, and soon, you'll be crafting barista-level espresso shots right in your kitchen.
