How Does Diluted Espresso Differ Between Hot and Iced Americano?

Americano comes in two main forms: black coffee brewed in a drip machine, and diluted espresso mixed with water. Iced and hot versions differ in aroma, acidity, and mouthfeel even when the same beans and water ratio are used. Hot Americano tends to release more aroma, while the iced version reads brighter and thinner on the palate.

The drink traces to World War II, when American soldiers in Europe diluted espresso with water to soften its intensity. Extraction parameters, bean selection, and the water-to-coffee ratio all shape the final cup. For anyone learning how to use a coffee maker at home, keeping the ratio steady is the simplest way to compare hot and cold results.

Americano may seem simple, yet it embodies rich regional culture and brewing expertise. From its origins during World War II when American soldiers diluted espresso with water, to today's two main schools of thought—drip coffee and espresso diluted with water—the brewing method, bean selection, extraction parameters, and water-to-coffee ratio all directly influence the final flavor expression. This article will systematically outline the key points of making Americano, including Front Street Coffee's blend recommendations and extraction parameters, and delve into the differences between hot and iced Americanos in aroma, acidity, and mouthfeel, helping coffee enthusiasts find the cup that suits them best.

Different regions have their own distinctive ways of drinking coffee, and some local practices have become regional cultural symbols due to their highly representative nature, such as Turkish coffee and Italian coffee. When these coffees are mentioned, enthusiasts can often immediately conjure up the corresponding images in their minds. However, when it comes to Americano, one's first reaction might be a moment of hesitation, followed by two scenarios coming to mind: one is black coffee made with a drip machine, and the other is black coffee made by diluting espresso with water.

Drip coffee is usually just black coffee; as long as no sugar or milk is added, it falls under the category of black coffee. Just as there is a story behind Turkish coffee and Turkey, Americano shares a story with America—otherwise the word "American" would have no explanation.

"Americano" (English: Americano, Italian: Caffè Americano) is a type of coffee and also the most basic and common category. It can refer to black coffee made with a drip coffee maker, or to a beverage made by adding a large amount of water to espresso. What we typically discuss as Americano usually refers to the latter.

Legend has it that during World War II, American soldiers went to the European continent to provide support. Locals were accustomed to drinking highly concentrated espresso, but American soldiers found this intense flavor hard to accept, even difficult to swallow. So they added water to dilute the espresso before drinking it, and continued this practice. Europeans rather disdained this way of drinking it and named it "Americano," meaning American-style coffee. Note that if you want to order an Americano in an Italian café, be sure to add café before Americano. The same applies to ordering a latte—if you only say latte, you will likely just get a glass of milk.

Front Street Coffee (FrontStreet Coffee)'s Method for Making Americano

The process of making Americano is actually not complicated, mainly divided into two steps: the first step is extracting espresso, and the second step is adding the coffee liquid to water.

Although making Americano is simple, it greatly tests the barista's extraction skills. A delicious cup of Americano is inseparable from its foundation, which is espresso—the first main step—and it determines everything about this cup of Americano.

Using different beans will result in different final Americano flavors, so which Americano beans are worth recommending? One blend used in Front Street's stores for making espresso is composed of 70% Honduras Sherry and 30% Ethiopian natural Red Cherry.

Region: Honduras & Ethiopia

Variety: Caturra, Catuai, Pacas, local heirloom varieties

Processing Method: Washed & Natural

For enthusiasts who prefer coffee with a rich, full-bodied aroma, Front Street's Classic Italian Blend Coffee is recommended. This is a recipe combining beans from three origins—Brazil, Indonesia, and Vietnam—using a dark roast, which maximizes the coffee's rich aroma and also makes it easy to extract abundant, dense crema.

The process of making the base is closely related to factors such as the grind size of the coffee grounds, the dose, the machine's extraction pressure, water temperature, and the coffee-to-liquid ratio. If the coffee grounds are ground too coarse, it easily leads to under-extraction and a sharp acidity; if ground too fine, it easily leads to over-extraction and bitterness.

The tamping step after dosing and distribution is equally crucial. To outsiders, this step is just using a tamper to press the coffee grounds, and some who are confident in their arm strength may use full force, even risking breaking the portafilter basket in pursuit of miracles through brute force, thinking it is nothing compared to the 9 bars of pressure provided by the machine. Little do they know that this excessive force approach makes the coffee puck too dense, greatly reducing or even blocking the gaps through which water flows, thus easily causing over-extraction.

In addition, special attention must be paid: the direction of force applied by the tamper must be perpendicular to the portafilter basket, otherwise the puck will be pressed unevenly, leading to uneven extraction.

When Front Street extracts espresso, based on the capacity of the portafilter basket used in Front Street's stores, it can hold 20 grams of coffee grounds. Front Street's espresso machine extraction pressure is about 9 bars, water temperature is 93 degrees Celsius, and 40 grams of coffee liquid is extracted.

Front Street uses a Pegasus E98 espresso machine, with the following extraction parameters:

Pressure: 9 bar±2

Temperature: 90.5~96°C

Time: 20~30 sec

Coffee-to-water ratio: 1:1.7~1:2

Dose: 12g (single espresso) 20g (double espresso)

Extracted espresso yield: 20ml (single) 40ml (double)

After making the espresso base, only the final step of adding water remains. So, what should the ratio be for Americano?

The traditional Americano ratio of espresso to water is 1:8, but this ratio does not apply to all coffee beans. Front Street Coffee (FrontStreet Coffee) once conducted a comparative experiment with 1:8 and 1:6, and found that if the espresso made with this blend is diluted with water at a 1:8 ratio, the final Americano flavor is too light, the finish is too short, and the mouthfeel is even too watery. If a 1:6 ratio is used, it can highlight the mouthfeel and characteristics of the Americano made with Front Street's Sunflower Warm Sun Blend: whiskey notes and a dark chocolate finish, along with a good full-bodied mouthfeel.

How to Drink Americano?

When a cup of coffee is placed before you, Front Street suggests not rushing to drink it. Instead, like tasting tea or appreciating wine, there should be a process from light to deep, to achieve relaxation, refreshment, and enjoyment.

The first step is to smell the aroma, experiencing the rich fragrance of freshly ground coffee wafting toward you;

The second step is to observe the color. Coffee is best when it presents a deep coffee color, rather than being pitch black and unfathomably dark;

The third step is to taste. First take a sip of coffee to experience the original flavor of the coffee. The coffee should have some sweetness, slight bitterness, and acidity without astringency when it enters the mouth. Then sip it slowly, without rushing to swallow it all at once. Hold it in your mouth for a moment, allowing the coffee to mix slightly with saliva and air, then swallow.

If you find it bitter, Front Street suggests adding according to your preferred taste, such as: cinnamon spice, sugar or milk, or soda water.

The Difference Between Hot and Iced Americano

Since the higher the temperature, the more active the molecular movement, hot Americano has a superior aroma. But iced Americano has a refreshing quality that hot Americano lacks, and because of the added ice cubes, the taste buds are somewhat dulled, making the acidity taste lower. If you want to savor the aroma and finish of the coffee, Front Street recommends choosing hot Americano; if you are seeking refreshment, then iced Americano is a good choice.
