Dalgona coffee, a trendy beverage that took the world by storm in 2020, has been a subject of fascination for many coffee enthusiasts. The drink’s unique preparation method, which involves whipping instant coffee with sugar and water to create a creamy, velvety texture, has captivated the attention of social media platforms and coffee aficionados alike. However, despite its popularity, many people have reported struggling to achieve the perfect Dalgona coffee, with some even declaring it a “fail.” In this article, we will delve into the reasons behind Dalgona coffee’s failure and provide tips on how to overcome these challenges.
Understanding the Science Behind Dalgona Coffee
To comprehend why Dalgona coffee fails, it’s essential to understand the science behind its preparation. The drink’s signature texture is achieved through a process called “emulsification,” where two or more liquids that wouldn’t normally mix, such as oil and water, are combined to create a stable and smooth consistency. In the case of Dalgona coffee, the emulsification process occurs when the whipped coffee mixture is folded into the milk, creating a creamy and velvety texture.
However, emulsification is a delicate process that requires precise conditions to occur. If the conditions are not met, the emulsion can break, resulting in a separated or curdled texture. This is often the case with Dalgona coffee, where the whipped coffee mixture fails to incorporate with the milk, leading to a disappointing and unappetizing drink.
The Role of Instant Coffee in Dalgona Coffee Failure
One of the primary reasons behind Dalgona coffee’s failure is the use of instant coffee. Instant coffee is a highly processed product that has been stripped of its natural oils and flavor compounds. As a result, it lacks the necessary components to create a stable emulsion. When instant coffee is whipped with sugar and water, it can become over-aerated, leading to a fragile and unstable foam that collapses easily.
Furthermore, instant coffee can be too fine, which can cause it to become over-whipped and turn into a bitter, unpleasant-tasting mixture. This is because the fine particles of instant coffee can become over-oxidized, leading to a loss of flavor and aroma.
Choosing the Right Instant Coffee for Dalgona Coffee
While instant coffee can be a contributing factor to Dalgona coffee’s failure, it’s not impossible to achieve a good result with the right type of instant coffee. Look for an instant coffee that is made from 100% Arabica beans and has a medium to coarse grind. This type of instant coffee will be less prone to over-aeration and will have a more balanced flavor.
Additionally, consider using a high-quality instant coffee that is specifically designed for whipping. These products usually have a higher fat content and are formulated to create a stable and creamy foam.
The Importance of Sugar in Dalgona Coffee
Sugar plays a crucial role in the preparation of Dalgona coffee, as it helps to stabilize the foam and create a smooth texture. However, using too much or too little sugar can affect the final result. If too little sugar is used, the foam may not be stable enough, leading to a separated or curdled texture. On the other hand, using too much sugar can make the drink overly sweet and unbalanced.
The Science of Sugar in Dalgona Coffee
Sugar helps to stabilize the foam in Dalgona coffee by increasing the viscosity of the mixture. When sugar is whipped with instant coffee and water, it creates a network of sugar molecules that trap air bubbles, creating a stable and creamy foam. However, if too much sugar is used, it can become too viscous, leading to a dense and unpleasant texture.
Getting the Sugar Ratio Right
To achieve the perfect Dalgona coffee, it’s essential to get the sugar ratio right. A general rule of thumb is to use 1-2 tablespoons of sugar per 2 tablespoons of instant coffee. However, this ratio can vary depending on personal taste preferences and the type of instant coffee used.
The Role of Milk in Dalgona Coffee Failure
Milk is another critical component of Dalgona coffee, as it helps to create a creamy and velvety texture. However, using the wrong type of milk or incorrect temperature can affect the final result.
The Science of Milk in Dalgona Coffee
Milk contains casein, a protein that helps to stabilize the foam in Dalgona coffee. When milk is folded into the whipped coffee mixture, the casein molecules help to create a strong and stable emulsion. However, if the milk is too hot or too cold, it can affect the stability of the emulsion, leading to a separated or curdled texture.
Choosing the Right Milk for Dalgona Coffee
To achieve the perfect Dalgona coffee, it’s essential to choose the right type of milk. Whole milk or half-and-half is recommended, as they contain a higher fat content that helps to create a creamy and velvety texture. Avoid using skim milk or non-dairy milk alternatives, as they can be too watery and may not provide the necessary stability for the emulsion.
Tips for Achieving the Perfect Dalgona Coffee
While Dalgona coffee can be a challenging drink to prepare, there are several tips that can help to achieve the perfect result.
- Use high-quality instant coffee that is made from 100% Arabica beans and has a medium to coarse grind.
- Use the right amount of sugar, as too little or too much can affect the final result.
- Choose the right type of milk, such as whole milk or half-and-half, and ensure it’s at the correct temperature.
- Whip the coffee mixture until it becomes stiff and holds its shape, but avoid over-whipping.
- Fold the whipped coffee mixture into the milk gently, using a spatula or spoon.
- Experiment with different ratios of coffee to sugar to milk to find the perfect balance for your taste preferences.
By following these tips and understanding the science behind Dalgona coffee, you can overcome the challenges of preparing this trendy drink and achieve a delicious and creamy result.

What is Dalgona coffee and why is it prone to failure?
Dalgona coffee is a type of coffee drink that originated in South Korea and has gained popularity worldwide. It is made by whipping instant coffee powder with sugar and hot water to create a creamy, velvety texture. However, many people have reported difficulty in achieving the desired consistency, leading to a “Dalgona coffee conundrum.”
The main reason for the failure of Dalgona coffee is the incorrect ratio of coffee to sugar to water. If the ratio is not balanced, the mixture may not whip up properly, resulting in a flat or grainy texture. Additionally, using low-quality instant coffee powder or not whipping the mixture long enough can also lead to failure.
What is the ideal ratio of coffee to sugar to water for Dalgona coffee?
The ideal ratio of coffee to sugar to water for Dalgona coffee is 1:1:1. This means that for every 1 tablespoon of instant coffee powder, you should use 1 tablespoon of sugar and 1 tablespoon of hot water. However, this ratio can be adjusted to suit individual tastes and preferences.
It’s also important to note that the quality of the instant coffee powder can affect the ratio.
