Introduction:Although Americano, Long Black, and Lungo are all black coffees made by adding hot water to espresso, their brewing methods, flavor profiles, and cultural backgrounds are quite different. Understanding their historical origins, brewing details, and taste differences can not only help you choose the black coffee that best suits your palate more accurately, but also enable you to make more professional decisions when ordering or brewing at home.
Among the many types of coffee, those made by adding water to espresso are very popular, with Americano, Long Black, and Lungo being the most frequently compared. Though these three coffees may seem similar, they actually differ significantly in brewing steps, the ratio of coffee to water, crema retention, and overall flavor expression.
The origin of the Americano can be traced back to World War II, when American soldiers stationed in Europe were not accustomed to the intense strength of espresso and would dilute it with hot water to make the taste closer to the drip-style black coffee they were used to in the United States. This practice later evolved into what we now know as the Americano, which is characterized by using espresso as the base and reducing its concentration with a large amount of hot water. The typical coffee-to-water ratio ranges from 1:5 to 1:8, depending on personal taste.
Long Black is a uniquely Australian style of black coffee, characterized by pouring hot water first and then adding a double shot of espresso. This method helps preserve more crema (the coffee’s oily layer), resulting in a smoother mouthfeel and a more concentrated flavor. Long Black is generally served in a cup of about 150ml, with less total water than an Americano and a relatively higher proportion of espresso, giving it a bolder flavor that suits drinkers who prefer a stronger coffee taste. In Australian coffee culture, Long Black is a classic choice for black coffee, contrasting with milk-based drinks like lattes and Flat Whites.
Lungo, which means “long” in Italian, is a coffee made by extending the extraction time of an espresso machine. The typical extraction time is about one minute, yielding around 50–60ml of coffee. If the extraction continues, it can reach nearly 200ml. The characteristic of Lungo lies in using a longer extraction time to allow more water to pass through the coffee grounds, thereby extracting different flavor layers, though it may also bring more impurities and a slightly bitter taste. Compared to directly diluted coffee, Lungo retains more of the original espresso flavor profile, but the overall taste is cleaner and the volume greater.
In practice, an Americano is usually made by pouring espresso directly into a cup and then adding hot water. This order can cause some of the crema to disperse, though some people prefer this method as it releases more coffee aroma. For Long Black, it is recommended to pour the hot water first and then carefully add the espresso, which helps preserve the crema layer and enhances the overall smoothness and richness of the drink. Lungo requires adjusting the extraction time and water volume settings of the espresso machine. A medium-fine grind is generally recommended, with pressure and flow rate fine-tuned according to the machine’s characteristics to achieve a balanced extraction flavor.
In terms of proportions, the amount of water added to an Americano is more flexible, typically adjustable between 1:3 and 1:8 based on personal preference, though the mainstream ratio is around 1:5. The coffee-to-water ratio for Long Black is more concentrated, often presented at a 1:3 ratio, using a double shot of espresso with 100–120ml of hot water to emphasize a bold and layered flavor. The coffee-to-water ratio for Lungo is adjusted due to the extended extraction time. Although the liquid volume is greater than that of a standard espresso, it still maintains the fundamental flavor characteristics of espresso.
Additionally, many coffee enthusiasts also try to recreate these three types of coffee at home. For an Americano, it is recommended to use medium-dark roasted coffee beans to highlight its rich and toasty flavors. Long Black is suited to high-acidity and high-aroma blended beans, allowing layers to shine even with a smaller amount of water. Lungo can be made with a more balanced blend, using a slightly longer extraction time to bring out more flavor nuances. Regardless of which one you choose, proper grind size and water temperature control are key factors affecting the final taste.
In summary, Americano, Long Black, and Lungo each have their own unique historical background and brewing philosophy. Whether you prefer a light and smooth black coffee or a bold and robust one, understanding the differences among these three will help you make more suitable choices when selecting coffee and allow you to better appreciate the unique charm of each.
