Iced lattes may seem like they only require pouring ice cubes, milk, and espresso into a glass in sequence, but to truly make a delicious iced latte, there is much to consider—from ingredient selection to ratios to operational details. This article focuses on three key aspects: first, how to choose the right coffee beans and milk; second, the proper ratio between espresso, milk, and ice; and third, the operational details to pay attention to during extraction and assembly. Using specific data as examples, the article explains the reasoning behind the ratios and offers flexible adjustment suggestions to help coffee enthusiasts make a well-balanced iced latte at home.
Making espresso-based coffee is a barista's basic skill, and almost every café serves such drinks. What we commonly call espresso-based coffee is a series of coffee drinks built on espresso as the base. Today, let's make the easiest milk coffee among espresso drinks—an iced latte.
An iced latte looks extremely simple to make—【add ice, pour milk, pour coffee】and it seems done. Yet behind these seemingly easy steps, making a satisfying iced latte still requires considerable thought and understanding.
Point One: Choosing the Right Ingredients
Why is an iced latte so simple that almost every coffee bean brand includes it on their menu, yet the taste of iced lattes made by different brands is never exactly the same? One of the most critical reasons lies in the differences in ingredients such as milk and coffee beans.
The flavor of coffee beans can very directly influence the taste direction of an iced latte. Most espresso blends give an iced latte a rich nutty, chocolatey character. We recommend Front Street Classic Blend and Front Street Dark Cocoa Base Blend—they use medium-dark roasting, have fine crema, and a mellow body, easily replicating the taste of café-style lattes. There are also a few coffee beans that can highlight the sweetness and richness of milk in an iced latte. You can choose Front Street Strawberry Candy Espresso Blend or Front Street Grana Geisha SOE—they carry rich fruit flavors with low bitterness, and when paired with milk, the result is smooth and sweet.
The choice of milk is equally important. Within the category of whole fresh milk alone, there are over a dozen common options on the market. Among these milks, some are thick and rich, while others are as light as water. The standard for choosing milk is not simply to pursue thickness or a strong milky flavor, but to find the one that pairs well with coffee. Too heavy a milky flavor will overpower some of the coffee's own taste, while watery milk will make the latte bland.
Point Two: A Reasonable Milk-to-Coffee Ratio
Does choosing good coffee beans and good milk mean you can make a delicious iced latte? The premise is getting the ratio right. Front Street's iced latte uses Front Street Dark Cocoa Blend coffee beans and Vitasoy fresh milk, with an espresso-to-milk ratio of 1:6—that is, 40 grams of espresso liquid, paired with 240 grams of iced milk and 75 grams of ice cubes, finally served in a transparent glass of about 300ml capacity.
This ratio is for reference only—it is not the golden ratio for lattes. Front Street arrived at these parameters after multiple ratio adjustments using the above ingredients, based mainly on real tasting feedback. So when making an iced latte, you can also adjust the ratio accordingly—more milk will mask the coffee flavor, less milk will make it bitter, and more ice will make it diluted.
Point Three: Details in the Process
Just as the 【add ice, pour milk, pour coffee】method for iced lattes is simple and clear, there are actually still some small details worth noting. The most important is espresso extraction—whether a latte tastes good depends on whether the espresso extraction meets standards. Common espresso extraction issues like channeling and incorrect extraction time will naturally affect the taste of an iced latte.
The process of making an iced latte should also be quick—"quick" here means the time ice and milk spend in the glass should be as short as possible, and the extracted espresso should be poured into the glass immediately. This is also why a freshly made iced latte shows a gradient layer formed by milk and coffee. If the ice soaks in the milk for too long, the ice will melt, a water layer will appear on top, and the entire drink will become diluted when consumed.
Espresso is even more sensitive. Freshly extracted espresso has very rich crema, but after 30 seconds, the crema noticeably decreases. Espresso without crema also has difficulty floating on the surface.
