The Origin and Evolution of Americano: From WWII Soldiers' Drink to a Modern Café Classic

Introduction:Americano is a common beverage in coffee shops around the world, but its origins actually stem from American soldiers during World War II who were unaccustomed to the strong taste of Espresso. From its earliest form as a diluted drink to its promotion by brands like Starbucks today, the definition and preparation methods of Americano have always been controversial. This article will take you through its historical background, different brewing methods, and whether it truly qualifies as black coffee, helping you gain a deeper understanding of this classic drink.

Americano has now become a common choice in coffee shops worldwide, but its origin is actually closely tied to the U.S. military during World War II. At the time, many American soldiers stationed in Southern Europe found the intense and concentrated flavor of Espresso hard to adjust to, so they began adding hot water to dilute the Espresso and make it easier to drink. This practice of diluting Espresso gradually became a common habit among the troops and laid the foundation for the term “Americano.”

It’s worth noting that before World War II, most Americans were accustomed to brewing coffee using the drip method and preferred coffee with a lighter flavor. Even today, drip coffee makers remain a standard fixture in many American kitchens, which is why the drip coffee maker is often referred to as an “Americano coffee maker.” The widespread popularity of diluting Espresso with water can also be attributed to Starbucks’ global expansion, bringing this battlefield-born drink into coffee shops around the world.

However, there has always been considerable debate about how Americano should be made. One point of contention is whether using an espresso machine to extract coffee for a long time to produce a milder brew is appropriate. There are two very different views on this within the industry.

Traditional Espresso enthusiasts are usually reserved about this long extraction method. They believe that excessive extraction time can easily lead to over-extraction, especially in the later stages of brewing, where undesirable impurities from the coffee grounds and excessive caffeine are released, affecting the overall flavor and even making the coffee taste bitter. Therefore, they generally do not recommend using this method to make what is called an “Americano.”

However, in some international markets, such as Australia, this method is quite common. Many local coffee shops believe that as long as the final flavor is balanced, long extraction itself isn’t an issue. They also point out that if long extraction time is deemed inappropriate, then brewing methods like the French press or siphon coffee makers, which often involve even longer extraction times, shouldn’t be considered valid either.

Setting aside subjective taste judgments, one thing is certain: the lightly brewed coffee produced through long extraction actually contains more caffeine than simply diluting a standard shot of Espresso with hot water. This is due to the influence of the total amount of coffee grounds used and the extraction time, resulting in a greater total release of caffeine. Therefore, if you’re concerned about caffeine intake, this is worth keeping in mind.

In practical preparation, there are two main ways to make Americano: one is to first extract a standard shot of Espresso using an espresso machine and then dilute it with hot water; the other is to pour hot water into a cup first and then add the Espresso into the water. Both methods have their supporters—the former allows for more precise control over the quality of the Espresso, while the latter can sometimes result in a more evenly integrated flavor.

Overall, although Americano is often seen as “a type of black coffee,” it actually differs in preparation principle from traditional black coffee brewed directly (such as pour over or French press). If we distinguish based on whether milk or sugar is added, then an Americano with no additives can indeed be categorized as black coffee; however, in terms of extraction method and flavor characteristics, it is closer to “diluted Espresso.”

Regardless of which brewing method you prefer, understanding the history and evolution of Americano can help you appreciate it more when drinking and allow you to choose the most suitable brewing style according to your taste preferences. Whether you’re brewing at home or ordering at a café, you’ll be able to make your choice with more confidence.
