What is espresso?
By Yor Ramirez, President, Technical Head and Master Roaster at Procaf
Espresso is much more than just a drink: it is an art, a science and a passion. As president and master roaster at Procaf, I am proud to share with you the secrets of this iconic coffee preparation. In this article, we'll explore the different brewing methods for making the perfect espresso and the differences between espresso and other types of coffee brewing, like filter, French press, and aeropress.
Brewing Methods for Espresso
Espresso is made by passing hot water under high pressure through finely ground coffee. This process quickly extracts the aromas and essential oils from the coffee, creating a concentrated, rich and flavorful drink. Here are the essential steps to prepare a perfect espresso:
-
Bean selection : The quality of the espresso depends greatly on the coffee beans used. At Procaf, we select high-quality beans and roast them carefully to extract the best.
-
Grinding : The grind must be fine and uniform to ensure homogeneous extraction. A grind that is too coarse will result in a bland espresso, while a grind that is too fine will produce a bitter drink.
-
Tamping : The ground coffee is tamped into the filter holder with uniform pressure. Improper tamping can result in uneven extraction.
-
Extraction : The water is heated to a temperature which can vary between 90 and 98 degrees Celsius, and passed under a pressure of approximately 9 bars through the ground coffee for a period which, depending on the desired result, can be between 25 and 40 seconds. The result is a small cup of espresso with golden crema on the surface, a sign of successful extraction.
The Differences Between Espresso and Other Coffee Preparation Methods
Filtered
Drip coffee is one of the most common and simplest methods of brewing coffee. Hot water is poured over ground coffee in a filter, and the coffee brews slowly before passing through the filter into a carafe. Unlike espresso, filter coffee is less concentrated and has a smoother, more subtle flavor. The grind is coarser, and extraction takes longer, usually 4 to 6 minutes.
French Press
The French press, or French press, is another popular method. It involves mixing coarsely ground coffee with hot water in a carafe and letting it steep for about 4 minutes. Next, a plunger with a metal filter is pressed down to separate the coffee grounds from the drink. Coffee made with a French press has a rich, full taste because the essential oils and fine particles are not filtered out.
Aeropress
The aeropress is a more recent and innovative method. It combines aspects of espresso and French press. Ground coffee is mixed with hot water in a cylinder, then a plunger is used to force the water through the coffee and a paper filter. Extraction takes about a minute. Coffee made with an aeropress is often more concentrated and has a clean, bright taste, similar to espresso, but with less crema.
Conclusion
Espresso is a unique brewing method that delivers an intense, aromatic coffee experience. As a master roaster at Procaf, I believe that understanding the different methods of preparing coffee enriches our appreciation of this complex and delicious beverage. Whether you prefer espresso, drip coffee, French press or aeropress, each method has its own merits and brings something special to your daily cup of coffee.
