Espresso
Espresso is both the name of a coffee brew and a method of brewing coffee that originated in Italy. The word "espresso" comes from the Italian term meaning "pressed out," which describes the process the drink is made. This brewing method involves forcing a small amount of hot water through finely-ground coffee at a high pressure for about 20-25 seconds using an espresso machine. The modern espresso machine was invented in 1884 by Angelo Moriondo in Turin, Italy, and it was refined and upgraded over the decades to machines we have now.

Coffee Beans and Caffeine Content of Espresso
Espresso blends commonly contain robusta in addition to some arabica beans to increase the caffeine content, but despite the increased caffeine content, there is actually a false belief of thinking that a shot of espresso contains more caffeine than a cup of filter coffee. Caffeine content in one Espresso shot (30ml or 1oz) is around 80mg, and the fact is that even though espresso is more concentrated than other coffee beverages, it is served in smaller quantities than, for example, a cup of drip coffee, and that results in a total caffeine content that is actually lower than in other larger coffee drinks. But for many who enjoy espresso, they drink it as a shot, and the intense flavor and high caffeine concentration make the espresso a go-to for a quick energy boost.

Variations of Espresso
Though the standard serving of espresso is a single shot (about 30ml), there are several variations:
-
What's the Difference? Espresso vs. Ristretto
While both drinks use the same coffee beans and brewing methods, the main difference between a Ristretto and a regular Espresso lies in the amount of water and brewing time. Ristretto is brewed with half the water used for espresso, making it more concentrated and intense. If a typical Espresso is extracted for about 20-25 seconds, then Ristretto is typically done in about 10–15 seconds, cutting off the extraction before the water begins to dilute the rich flavor.
-
What's the Difference? Espresso vs. Doppio
A double shot of espresso, typically 60ml.
-
What's the Difference? Espresso vs. Lungo
A "long" espresso shot, brewed over a longer period of time using more water, creating a larger and more diluted espresso shot but still weaker than drip coffee.
Espresso is the Main Ingredient of Other Coffees
Espresso serves as the basis for many other coffee drinks, especially those that incorporate milk or cream (or even ice cream). Some of the most well known drinks include:
- Caffè Latte: Espresso with steamed milk and a small amount of milk foam on top.
- Cappuccino: Equal parts espresso, steamed milk, and milk foam, often topped with cocoa powder or cinnamon. Read more: Cappuccino
- Caffè Americano: Espresso diluted with hot water, resembling the strength of drip coffee but retaining the unique flavor of espresso. Read more: Caffè Americano
- Caffè Macchiato: Espresso "stained" with a small amount of steamed milk or foam.
- Flat White: Similar to a latte but with a thinner layer of milk foam, part of the Australian and New Zealand coffee culture. Read more: Flat White
