The Perfect Iced Americano: Water and Ice Ratios Explained

Waking up in the morning, grab a glass, add some ice and a little water, and finally pour in the extracted espresso - a refreshing and energizing iced Americano is ready!

As most people know, adding ice and water is meant to dilute the concentration of espresso, making the coffee more palatable. However, some friends might struggle with the question: "How much ice should be added to an Americano? How much water should be mixed in?" So today, FrontStreet Coffee will discuss how much water and ice should be added to espresso, and how to add them properly.

How Much Water to Add?

The flavor of an Americano mainly comes from the beans, so the dilution ratio depends on the flavor profile of the beans. For example, some classic dark-roasted beans with flavors of caramel, nuts, and dark chocolate tend to taste more bitter and concentrated in espresso, so you can use a larger ratio for preparation, approximately 1:6 to 1:8 liquid-to-water ratio. For instance, 40 grams of espresso mixed with 240-320 grams of water. If you prefer a lighter taste, use 1:8; if you like it more concentrated, use 1:6.

For coffee beans with relatively lighter roasts like SOE (Single Origin Espresso), their flavor profile is not just bitterness but also showcases fruit acidity and sweetness, so there's no need to dilute it as much. You can use a ratio of about 1:5. For example, 40 grams of coffee liquid mixed with 200 grams of water.

Take FrontStreet Coffee's daily used Warm Sun Blend espresso beans as an example. To showcase the unique wine aroma, vanilla, and cream flavors of these beans, FrontStreet Coffee chose an extraction plan using 20 grams of coffee beans to extract 40 grams of espresso liquid, with an extraction time of 27-28 seconds. After multiple rounds of testing and comparison, we finally determined a 1:4.5 Americano water ratio, which means 40 grams of coffee mixed with 180 grams of water.

People's preferences for coffee concentration vary widely, so feel free to try several ratio options to find the concentration that best suits your taste, thereby determining how much water to add to your Americano.

How to Add Water and Ice?

The addition of ice not only quickly cools down the drink but also dilutes the concentration of espresso. Therefore, when determining the ice-to-water ratio for an iced Americano, you need to consider the melting speed of the ice simultaneously.

Take FrontStreet Coffee's iced Americano as an example. Today's Warm Sun espresso extraction parameters are: using 20g of coffee grounds to extract 38g of coffee liquid in 29 seconds, with a coffee-to-ice-water ratio of 1:6.5, and an ice-to-water ratio of approximately 1:1.8. That means 38g of coffee mixed with 90 grams of ice and 160 grams of water.

Looking at these ratio values, the concentration seems quite diluted. This is because FrontStreet Coffee uses large, hard ice cubes that have been frozen for at least two to three days, each weighing about 30 grams, and we use pre-chilled ice glasses. Therefore, the ice melts relatively slowly. About 15 minutes after serving, you can still see chunky ice particles, and some customers who drink quickly may still have nearly intact ice cubes in their glasses.

So while the concentration appears lower, it doesn't actually affect the tasting of the coffee's flavor, while also maintaining the low temperature of the iced Americano (Warm Sun doesn't taste good at room temperature). Therefore, when we determine the ratio between ice and water in our daily iced Americano preparation, we also need to consider the melting speed of the ice used in the coffee.

If you're using smaller ice cubes that haven't been frozen for long, we suggest appropriately increasing the proportion of ice. For example, FrontStreet Coffee's ice-to-water ratio is 1:1.8, but you could increase it to 1:1. That means 40 grams of espresso mixed with 100 grams of water and 100 grams of ice, ensuring the coffee stays diluted while maintaining a low temperature for a better drinking experience.

A Simple Tip

Some friends might be unsure about the melting speed of their ice cubes, unable to control exactly how much ice and water to add, and don't want to do too much calculation. FrontStreet Coffee has an additional simple tip to share.

Take your regular iced Americano glass, fill it completely with ice, then add water to about 80% full, and finally pour in the espresso and stir well (try to pour the coffee over the ice cubes). If you find it too concentrated after tasting, then use less ice and more water next time; if you find it too weak and lacking flavor, use less water next time.

Of course, Americano coffee originally evolved because Americans weren't accustomed to drinking overly concentrated espresso and added water to dilute it, so there's no fixed standard. Moreover, diluted espresso at low temperatures has high compatibility - as long as the extracted espresso tastes good, being slightly more concentrated or slightly diluted won't increase or decrease the original flavors of the coffee. Therefore, you still need to combine your own dietary habits, try more based on the flavor characteristics of the beans, and find the ratio and concentration that you like best - that's where the charming appeal of coffee lies.
