Espresso is the foundation of most specialty coffee drinks. A well-prepared espresso delivers a balanced combination of sweetness, acidity, body and aroma that defines the quality of the final cup.
Whether enjoyed on its own or used as the base for drinks such as cappuccino, latte, flat white, americano, cortado or macchiato, mastering espresso preparation is one of the most valuable skills for any barista.
In this guide, you'll learn the essential parameters and professional techniques used to prepare the perfect espresso.
Espresso is a concentrated coffee beverage produced by forcing hot water under pressure through finely ground coffee.
A quality espresso should offer:
A good starting point is 25 seconds.
Depending on the coffee origin, roast profile and grind size, slight adjustments may improve the final flavor.
Recommended doses are:
A traditional espresso generally yields between 25 and 35 ml.
These parameters are guidelines, but taste should always be the final judge.
Rinse the cup with hot water before brewing to maintain the espresso's serving temperature.
Ensure the portafilter is completely clean and dry before dosing coffee.
Add the correct amount of coffee and ensure the grind size is properly calibrated.
Too coarse results in under-extraction and sour flavors; too fine can lead to over-extraction and bitterness.
Level the coffee bed to eliminate air pockets and reduce channeling.
Apply firm, level pressure with the tamper to create a compact and even coffee puck.
A slight twist of the tamper can help smooth the surface of the coffee bed.
Remove loose grounds from the basket and portafilter edges.
Run water through the group head briefly before brewing.
This removes coffee residue and stabilizes temperature.
Insert the portafilter and begin extraction without delay.
The espresso should flow evenly with a texture similar to warm honey.
Watch both extraction time and yield.
Knock out the spent puck immediately after brewing.
Rinse and dry the portafilter thoroughly.
Flush the group head to remove oils and coffee particles.
Keep the portafilter locked into the machine so it remains warm and ready for the next shot.
