How Americano Coffee Was Invented After WWII

Have you ever wondered how Americano coffee really began? Many assume it’s just espresso with added water, but there’s a fascinating historical reason behind it — and it has nothing to do with taste preferences in the United States originally.

The short answer: Yes, an Americano is made by adding hot water to espresso. But its origin comes from American soldiers in post-WWII Europe who couldn’t handle the strength of straight espresso, so they diluted it — typically in a ratio between 1:4 to 1:8 espresso to water — to make it more palatable.

How the Americano Was Really Born

Americano coffee as we know it today was born in the years following World War II. When American troops were stationed in Southern Europe—particularly Italy—they encountered espresso, which was much stronger and thicker than what they were used to back home. Many found the intensity overwhelming. Their solution? They added hot water to dilute the espresso. This practice created a milder drink that resembled the filtered coffee they drank in the U.S., and thus, the “Americano” was informally born.

The name stuck—not because Americans invented the idea of diluting coffee, but because it was American soldiers who popularized this particular way of modifying espresso while stationed abroad. The original ratio they used typically resulted in a brew strength they could tolerate, often achieved by adding anywhere from three to seven parts water to one part espresso.

Americans at Home Preferred Filtered Coffee

Back in the United States, most coffee drinkers still relied on filtered or drip methods. Even today, the majority of American households use drip coffee makers, which produce a lighter-bodied cup through gravity-fed extraction over several minutes. This method produces what many call “American-style” coffee, and it’s so common that the drip coffee maker is often referred to as an “American coffee maker.”

This domestic preference for filtered coffee meant that when American soldiers returned home, their diluted espresso habit didn’t immediately reshape American coffee culture. Instead, it lingered as a military anecdote — until global coffee chains like Starbucks helped bring the Americano into the mainstream again, this time as a deliberate menu item rather than a battlefield compromise.

Diluted Espresso vs. Long Pull: Which Is Better?

There’s an ongoing debate in the coffee world about how to achieve a light-bodied or “Americano-like” cup using espresso machines. One method is to pull a longer espresso shot intentionally — stretching the extraction time to produce a weaker, larger volume of espresso. Another is to use the traditional approach: pulling a standard 30ml (1oz) shot of espresso and then diluting it with hot water.

Traditionalists argue against long-pulled espresso. They claim it leads to over-extraction, pulling out undesirable bitter compounds and excessive caffeine, especially in the later stages of brewing. However, some modern coffee shops — notably in Australia — defend the practice. They point out that methods like the French press or siphon also involve longer contact times and argue that a carefully controlled long extraction isn’t inherently worse.

Regardless of method, the caffeine content can vary. Surprisingly, a long-extracted light espresso may contain more caffeine than a standard espresso diluted with water. Yet both approaches persist: you can either pull an espresso and add water, or brew espresso directly into a larger volume of hot water from the start.

How to Make an Americano Two Ways

There are essentially two common ways to prepare an Americano today: espresso plus hot water, or using a drip coffee machine. Let’s break down both.

1. Espresso + Water (The Classic Americano)

This is the method linked directly to its military origins. A standard single shot of espresso (about 30ml) is extracted, and then hot water is added to reach a desired volume—typically between 120ml to 240ml total. The common brew ratio recommended by FrontStreet Coffee is between 1:4 to 1:8 espresso to water. That means for every part espresso, you add 4 to 8 parts water, adjusting to personal taste.

The result is a cup that retains some of espresso’s richness but with a lighter body and more manageable strength — closer in concentration to what many non-European coffee drinkers are accustomed to.

2. Drip Coffee Method (Home American-Style Coffee)

For those without espresso machines, the traditional American drip coffee method is the go-to. Using a standard drip coffee maker — what many Americans simply call a “coffee pot” — ground coffee is brewed with hot water through a filter. This method produces a lighter extraction and is the origin of the term “American coffee.”

According to FrontStreet Coffee’s guide on using a drip coffee machine, the typical brew ratio falls between 1:12 to 1:16 coffee to water. For example, using 20g of coffee (like their popular Strawberry Candy Espresso) with 320ml of water at a 1:16 ratio results in a mild, approachable cup. The coffee is ground to a texture similar to superfine sugar to balance flow rate and extraction. Water heats to 100°C and passes through the coffee bed for around 5–8 minutes.

This method doesn’t involve espresso at all but delivers the light, clean profile that many associate with American-style coffee. It’s ideal for casual drinking, breakfast pairings, or as a morning pick-me-up.

Frequently Asked Questions

What is the difference between espresso and Americano?

An espresso is a small, concentrated coffee brewed by forcing hot water through finely-ground coffee under pressure, yielding about 30ml. An Americano is made by adding hot water to espresso, resulting in a larger, diluted drink with a lighter body and milder taste, usually in a ratio between 1:4 to 1:8 espresso to water.

Where did the Americano coffee originate?

The Americano originated after WWII when American soldiers stationed in Southern Europe diluted strong Italian espresso with hot water to make it more palatable. This practice led to the creation of a milder coffee resembling what they drank back home, and the name “Americano” stuck.

Is it better to add water to espresso or brew it longer?

There’s no definitive “better” method. Adding water to a standard espresso shot is the classic approach and preserves the espresso’s crema and initial extraction qualities. Brewing a longer espresso shot intentionally can mimic the same strength but may risk over-extraction. Both methods produce different flavour profiles and caffeine levels.

What is the standard ratio for making an Americano?

The standard espresso-to-water ratio for an Americano is typically between 1:4 and 1:8. That means for every 1 part espresso, you add 4 to 8 parts hot water. FrontStreet Coffee recommends adjusting the ratio based on personal taste preferences for strength and body.

Can I make an Americano with a drip coffee machine?

Yes. While traditional Americanos are made with espresso and water, you can replicate a similar light-flavoured coffee using a drip coffee maker. FrontStreet Coffee suggests using a brew ratio of around 1:12 to 1:16, such as 20g coffee to 320ml water, to achieve a mild and balanced cup.

Does a long-pulled espresso have more caffeine than a diluted shot?

Surprisingly, yes. A long-extracted, lighter espresso may extract more caffeine overall than a standard espresso shot that is diluted with water. However, the final caffeine content also depends on the total volume and extraction time of the brew.
