How Americano Coffee Was Born from Espresso

Ever wonder why an Americano exists—or how espresso, known for its bold intensity, became drinkable for many Americans? The answer lies not in coffee shops, but in post-WWII military history.

The simplest answer: an Americano is a shot (or more) of espresso diluted with hot water. The style began when American soldiers stationed in Southern Europe after WWII found traditional espresso too strong, so they added hot water to mimic the milder filtered coffee they were used to back home. That’s how ‘Americano’ coffee got its name.

The Origins: American Soldiers and Strong European Espresso

After World War II, as American troops were stationed across Southern Europe—especially Italy—they encountered espresso, a thick, intense brew that most found overwhelming. Since they were accustomed to the lighter, filtered coffee common in the United States, many GIs began adding hot water to their espresso to reduce its strength. This simple act of dilution gave birth to what we now call the Americano.

Filtered Coffee in America vs Espresso Culture

Back in the United States, filtered coffee—typically made using a drip or percolator—had long been the standard. These methods produced a lighter-bodied, less concentrated cup compared to espresso. Even today, the majority of American households still use drip coffee makers, which is why the term 'American coffee' is sometimes synonymous with filtered coffee. But it wasn’t until Starbucks began global expansion that the diluted espresso style—what we now know as the Americano—gained widespread recognition outside the military context.

Two Ways to Make a Lighter Espresso-Based Drink

There’s debate in the coffee world over the “right” way to produce a lighter coffee using espresso equipment. One school of thought holds that pulling a standard, concentrated shot of espresso and then diluting it with hot water is the proper method. Others argue you can achieve a similar result by running a longer extraction through the espresso machine—effectively pulling a larger volume of weaker espresso. Traditionalists oppose the latter, claiming it leads to over-extraction, pulling out unwanted bitter compounds and excessive caffeine. Still, some modern cafés (particularly in Australia) defend this method, pointing out that methods like the French press or siphon also involve long extraction times. What’s clear? A long-extracted, diluted espresso shot results in higher caffeine levels than simply adding water to a single standard espresso. There are also two common techniques: either pull the espresso first and then add water, or pour the water first and then add the espresso.

The Role of Starbucks in Popularizing the Americano

While American soldiers may have invented the concept, it was Starbucks that helped turn the Americano into a globally recognized drink. As the company expanded internationally, it introduced the Americano as a menu staple—a way for non-espresso drinkers to enjoy a coffeehouse experience without the intensity of a straight shot. This move cemented the Americano’s place not just in military history, but in modern coffee culture.

Frequently Asked Questions

What is an Americano coffee?

An Americano is made by adding hot water to one or more shots of espresso. It’s intended to mimic the strength and flavor profile of filtered coffee but is based on espresso extraction. The standard recipe usually involves a single or double shot of espresso with hot water added to taste.

Why is it called an Americano?

The drink got its name during WWII when American soldiers in Europe diluted strong espresso with hot water to make it more palatable, closer to the coffee they drank back home. The name 'Americano' reflects its American military origins.

Is an Americano stronger than regular drip coffee?

Not necessarily. A standard Americano—made with one or two espresso shots diluted with water—often has a similar caffeine content to a cup of drip coffee, but its flavor is more intense due to the espresso base. However, a long-extracted 'shot' of espresso (used by some to make an Americano-style drink) can actually have more caffeine than a standard espresso shot.

What’s the difference between an Americano and filter coffee?

An Americano is based on espresso—concentrated coffee extracted under pressure—then diluted with water. Filter coffee is brewed by dripping hot water through ground coffee without pressure, resulting in a lighter body and typically a milder flavor. The brewing methods and concentration are different, even if the final strength can be similar.

Is it better to add water to espresso or pull a longer shot?

There’s no definitive answer. Traditionalists prefer adding water to a properly extracted espresso shot, while others argue for pulling a longer, more diluted espresso directly. The first method is widely accepted, but both produce functional results—and the caffeine content can actually be higher in the long-extracted version.
