Sugar plays a crucial role in the fluffiness of Dalgona coffee, as it helps to strengthen the foam and prevent it from collapsing. The type and amount of sugar used can affect the fluffiness of the foam, with granulated sugar being the most commonly used type of sugar in Dalgona coffee.
The Role of Sugar in Foam Stability
Sugar helps to stabilize the foam in Dalgona coffee by:
- Increasing the viscosity of the mixture: Sugar increases the viscosity of the mixture, making it more difficult for the air bubbles to escape and collapse.
- Reducing the surface tension of the mixture: Sugar reduces the surface tension of the mixture, making it easier for the air bubbles to form and stabilize.
The Effect of Temperature on Dalgona Coffee’s Fluffiness
Temperature is another factor that can affect the fluffiness of Dalgona coffee. The ideal temperature for whipping Dalgona coffee is between 150°F and 160°F (65°C to 71°C), as this temperature range allows for the optimal incorporation of air into the mixture.
The Impact of Temperature on Foam Stability
Temperature can affect the stability of the foam in Dalgona coffee by:
- Affecting the solubility of the coffee powder: Temperature can affect the solubility of the coffee powder, with higher temperatures making it easier for the coffee powder to dissolve and form a stable foam.
- Affecting the viscosity of the mixture: Temperature can affect the viscosity of the mixture, with higher temperatures making it more difficult for the air bubbles to escape and collapse.
How Long Does Dalgona Coffee Stay Fluffy?
The length of time that Dalgona coffee stays fluffy depends on several factors, including the type of coffee powder used, the ratio of coffee to sugar, and the temperature of the mixture. Generally, Dalgona coffee can stay fluffy for several hours if it is stored in an airtight container in the refrigerator.
Tips for Keeping Dalgona Coffee Fluffy
Here are some tips for keeping Dalgona coffee fluffy:
- Use a high-quality instant coffee powder: Choose an instant coffee powder that is made from high-quality coffee beans and has a low moisture content.
- Use the right ratio of coffee to sugar: Use a ratio of 1:1 or 1:2 (coffee to sugar) to ensure that the foam is stable and fluffy.
- Whip the mixture at the right temperature: Whip the mixture at a temperature between 150°F and 160°F (65°C to 71°C) to ensure that the foam is stable and fluffy.
- Store the mixture in an airtight container: Store the mixture in an airtight container in the refrigerator to prevent the foam from collapsing.

What is Dalgona coffee and why is it fluffy?
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 until it becomes creamy and fluffy. The fluffiness of Dalgona coffee is due to the incorporation of air into the mixture, which creates a light and airy texture.
The unique texture of Dalgona coffee is also attributed to the type of sugar used. Granulated sugar is typically used to make Dalgona coffee, as it dissolves easily and helps to create a smooth and creamy texture. When the sugar is whipped with the coffee powder and hot water, it creates a stable foam that gives the coffee its characteristic fluffiness.
How long does Dalgona coffee stay fluffy?
The fluffiness of Dalgona coffee can last anywhere from a few minutes to several hours, depending on various factors. If you whip the coffee mixture until it becomes stiff and holds its shape, it can last for several hours. However, if you don’t whip it enough, the fluffiness may dissipate quickly.
The temperature and humidity of the environment also play a role in determining how long the fluffiness lasts. If you serve Dalgona coffee in a hot and humid environment, the fluffiness may dissipate faster. On the other hand, if you serve it in a cool and dry environment, the fluffiness can last longer.
What factors affect the fluffiness of Dalgona coffee?
Several factors can affect the fluffiness of Dalgona coffee, including the ratio of coffee to sugar, the temperature of the water, and the whipping time. If you use too little sugar or too much coffee, the mixture may not whip up properly, resulting in a dense and flat texture.
The temperature of the water is also crucial in determining the fluffiness of Dalgona coffee. If the water is too hot, it can dissolve the sugar too quickly, resulting in a mixture that is too liquidy and lacks fluffiness. On the other hand, if the water is too cold, it may not dissolve the sugar properly, resulting in a grainy texture.
How can I make Dalgona coffee stay fluffy for longer?
To make Dalgona coffee stay fluffy for longer, you can try whipping the mixture until it becomes stiff and holds its shape. You can also add a stabilizer such as gelatin or agar agar to the mixture to help maintain its texture.
Another tip is to serve Dalgona coffee immediately after whipping, as the fluffiness can dissipate quickly if it is left to sit for too long. You can also try serving it in a cool and dry environment to help prolong the fluffiness.
Can I refrigerate Dalgona coffee to make it stay fluffy for longer?
Refrigerating Dalgona coffee can help to prolong its fluffiness, but it’s not a foolproof method. If you refrigerate the coffee, the fluffiness may dissipate faster due to the cold temperature.
However, if you whip the mixture until it becomes stiff and holds its shape, refrigerating it can help to maintain its texture for a longer period. It’s also important to note that refrigerating Dalgona coffee can cause it to separate, resulting in a layer of liquid at the bottom of the container.
Can I make Dalgona coffee ahead of time and still maintain its fluffiness?
While it’s possible to make Dalgona coffee ahead of time, it’s challenging to maintain its fluffiness. The fluffiness of Dalgona coffee is best preserved when it is served immediately after whipping.
However, if you need to make it ahead of time, you can try whipping the mixture until it becomes stiff and holds its shape, then refrigerating it until you’re ready to serve. You can also try whipping it again just before serving to restore its fluffiness.
What are some common mistakes that can cause Dalgona coffee to lose its fluffiness?
One common mistake that can cause Dalgona coffee to lose its fluffiness is over-whipping the mixture. Over-whipping can cause the mixture to become too stiff and dense, resulting in a loss of fluffiness.
Another mistake is using too little sugar or too much coffee, which can result in a mixture that is too dense and lacks fluffiness. Using the wrong type of sugar, such as brown sugar or honey, can also affect the texture of the coffee and cause it to lose its fluffiness.
