The biggest difference between an Americano and a long black is the order in which water and espresso go into the cup. An Americano adds hot water to a pulled shot of espresso, while a long black pours the espresso over hot water that is already in the cup. The ingredients are the same, but the order changes how much of the golden foam on top, called crema, survives.
Why does the order change the taste?
Crema is a layer of tiny bubbles formed while espresso is being pulled. When hot water is poured onto espresso, the stream breaks up this foam and most of it disappears. When espresso is poured onto water, the foam rests on the surface and more of it stays at the top of the cup. That is why many sources say a long black shows more aroma and foam texture in the first sip.
Opinions differ on how big the taste difference is. Some say the flavor is not very different when ingredients and amounts are the same, while others say texture and aroma change. Rather than declaring a winner, the most reliable way is to drink both with the same beans and choose the one you prefer.
How do size and strength differ?
Recipes vary by cafe, so there is no fixed standard. Commonly, a long black is described as a smaller cup with less water that tastes stronger, while an Americano uses more water and is a larger, smoother drink. These sizes are set by each cafe, so they are common rules of thumb rather than an official standard. The diagram below summarizes the points of comparison.
Telling them apart at home
If you have an espresso machine, just make two cups and swap the order. Without one, a moka pot or strongly brewed coffee can imitate it, but crema comes from machine pressure, so it will not look the same. Writing down water temperature and amount as you experiment makes it easier to find the strength you like. The order described here is the generally known method; when ordering, the surest way is to ask the cafe how they make it.
Frequently asked questions
Which one is stronger?
With the same amount of espresso, the one with less water is stronger. A long black often uses less water and feels stronger, but the cafe decides the water amount, so the same name can differ.
Does the caffeine change?
Caffeine depends on the amount of espresso. Whether water goes in first or last does not change it. See the caffeine guideline post for daily amounts.
Which should I order?
Many people choose a long black to enjoy the crema texture and aroma, and an Americano for a larger cup to sip slowly. There is no right answer, so try both.
