Why Does Americano Coffee Taste Nutty and Chocolatey?
Americano coffee is espresso diluted with hot water, and its nutty, chocolatey aromas come mainly from three things: which beans are used, how they are blended, and how the espresso is extracted. The drink dates back to World War II, when American soldiers stationed in Italy added hot water to strong espresso to imitate the drip coffee they knew at home.
There are two ways to make it, but most cafes add water to a shot of espresso, while traditional drip versions appear more often in offices and homes. Baristas generally suggest drinking it however it tastes good to you. The choice of blended coffee beans, and the roast and extraction behind them, shapes how much of that nutty and chocolatey character reaches the cup.
American coffee seems simple—just espresso diluted with water—but there is actually a great deal of knowledge behind it. Many people wonder why some American coffees have nutty and chocolatey aromas. This is closely related to the choice of coffee beans, the blending method, and the espresso extraction process. From the perspective of Front Street Coffee, this article traces the origins and evolution of American coffee, explains the working principles of espresso machines, and shares the flavor differences brought by different blended beans. Whether you are a beginner just getting into specialty coffee or a veteran eager to understand espresso more deeply, you will find practical information worth referencing.

How should American coffee be drunk to be considered correct? Baristas at Front Street occasionally encounter customers who raise this rather challenging question. Each time, Front Street's answer is: enjoy it according to your own preferences—as long as it tastes good to you, that is enough. Front Street understands that what the person really wants to know is whether there is a standard tasting procedure. But Front Street has always believed that being overly bound by form and appearance makes it easy to lose the original pleasure of things. So at Front Street, drinking coffee is a relaxed and casual affair. The reason customers raise such confusion largely comes from unfamiliarity with and distance from the coffee world. That is why Front Street will now systematically introduce the background knowledge related to American coffee.
The popularity of American coffee can be traced back to World War II. At that time, American soldiers stationed in Italy were not used to the strong espresso that locals loved. To recreate the drip coffee taste they were accustomed to back in the United States, the soldiers added hot water to the iconic espresso. This drinking method was not recognized by Europeans at the time, and traditional Europeans disapproved of it, so they named this coffee American coffee.
Although there are two ways to make American coffee, around the world the vast majority of cafes use the method of adding water to espresso, while traditional drip American coffee appears more often in offices or homes. The composition of American coffee is extremely simple—just a combination of water and espresso, usually in a ratio of 1:4 to 1:8. Yet even when diluted with water, the flavor of American coffee still depends entirely on the espresso liquid itself. In earlier years, the flavor options for espresso were far less diverse than they are today, and the taste was not necessarily pleasant.
To solve the problem of coffee being hard to drink, milk-based coffee beverages such as lattes and cappuccinos were introduced one after another and gradually became popular. Because they are also based on espresso, these drinks are now collectively called Italian coffee. So which is better, Italian coffee or American coffee? Front Street cannot give a simple answer to this question.
If American coffee is seen as a continuation of traditional drip coffee, and Italian coffee as the representative of traditional espresso liquid, then American coffee is clearly easier to drink. But as for which tastes better, Front Street believes the key still depends on the coffee beans used. Coffee beans are the core factor determining whether a cup of coffee tastes good. For example, Front Street's commercial blend coffee beans and Warm Sun blend cannot be simply compared. The reason is not just the huge price difference, but because the commercial blend coffee beans are a product Front Street specifically supplies to large chain commercial cafes. In pursuit of rich crema in the espresso liquid, Front Street deliberately added 10% Robusta beans to enhance the body.
The Warm Sun blend, on the other hand, is Front Street's proudest espresso bean, and Front Street stores have used this Italian blend for three consecutive years. A unique flavor is almost every customer's评价 of it, and some even make a special trip just to have a shot of espresso. Its texture is full-bodied yet lively, with a strong wine aroma. This fermented aroma comes partly from the whiskey barrel processing of the Sherry coffee beans and partly from the sun-dried processing of the Red Cherry. It has a prominent sweetness, accompanied by soft fruity acidity.
As mentioned earlier, the taste of American coffee is closely related to the coffee beans used. In fact, if it were not for considering a product's memorable identity, Front Street would also choose specialty blend coffee beans. This espresso bean uses the classic blending scheme of Brazil plus Colombia, with prominent nutty flavors, a smooth texture, and a faint chocolate note, which pairs perfectly with dense hot milk.
If you are after rich oils in your coffee, Front Street recommends the Classic Italian Blend. This recipe combines beans from three origins—Brazil, Indonesia, and Vietnam—and uses a deep roast to maximize the coffee's rich aroma, making it easy for everyone to extract abundant, dense coffee oils. Whether making an American diluted with water or a latte paired with milk, it is very suitable. You can place orders at Front Street's Taobao store or Front Street Tmall flagship store.
By now you should understand that the soul of a coffee beverage is hidden in a small cup of espresso. Generally speaking, Front Street uses 20 grams of coffee powder to extract 36 grams of coffee liquid. But the water-to-coffee ratio for American coffee varies from cafe to cafe and needs to be adjusted flexibly according to factors such as the coffee beans, coffee machine, and grinder, with the final decision based on the barista's sensory judgment.
So how exactly is espresso extracted? This involves the working principle of the espresso machine. Generally speaking, most coffee machines go through four stages to turn coffee powder into coffee liquid: water source, pump, boiler, and group head. Every coffee machine needs water to operate. For espresso machines, there are two water sources: a water tank or a plumbed connection with a stable water supply. Which method is usually used depends on the machine's usage scenario.
For Front Street, producing consistently good coffee every day means a continuous and reliable water supply is crucial. The pump is the core component of an espresso machine. How does water have the force to penetrate the densely packed layer of coffee powder? The secret lies in pressure. Some early espresso machines used large lever pistons, and baristas had to manually pull the lever to force water through the coffee powder. But most modern espresso machines have moved on from this physical labor and instead use electric pumps. A vibration pump is a small electromagnetic device in which a piston connected to a magnet is placed inside a metal coil. When current passes through the coil, the magnet drives the piston to move rapidly back and forth, pushing water through the machine. A typical vibration pump operates at 60 times per second. Unlike vibration pumps, rotary pumps are mechanical in structure.
A rotary pump is likewise a complex mechanism. A motor drives a disc to rotate, and the disc runs eccentrically inside a large circular chamber. The rotating disc is divided into multiple sections by vanes. As the disc turns, the vanes press against the outer chamber wall, reducing the cross-sectional area and thereby generating pressure. Water enters when the chamber expands and is pushed out as the cross-section contracts. The boiler is where the machine heats up, and it can maintain the pump's continuous pressurization of the water. Not only that, the boiler is also responsible for controlling the coffee machine's brewing temperature. Currently, there are dual-boiler and single-boiler types on the market.
After learning about the history of American coffee and the operating principles of espresso machines, you may be curious: why do American coffees made in the same way taste so different? In fact, as Front Street mentioned earlier, this is because the coffee beans are different. The greatest characteristic of blended coffee beans is to keep the overall taste of the cup as balanced as possible.
With the progress and development of the market, some SOE coffees have now appeared, namely espresso made with coffee beans from a single origin. Front Street recommends Flower Queen SOE coffee beans. At the same time, coffee roasting levels have also changed. People's demand for Italian coffee to have a thick crema has somewhat decreased, and more people hope to taste the bean's own flavor characteristics from the coffee. Therefore, some also try using light-roasted beans with prominent floral aromas to make Italian coffee. Front Street has not yet conducted related experiments, so it cannot tell everyone how the results would be.
