The denaturing of the proteins reveals their hydrophobic parts. These face the air in air bubbles, while the hydrophilic parts face the water surrounding the bubble. The denatured proteins bond to each other to form a structure that stabilizes the air pockets into foam.
Why is my Dalgona coffee so foamy?
You didn’t beat the mixture long enough
As you go along, the mixture will start to transform into a large foamy mass. Only stop whipping when the mixture has whipped up into medium-stiff peaks, otherwise you will get a foam that’s too soft, or too liquid to float on top of the milk.
What makes instant coffee foam?
Both instant coffee and regular ground beans “foam” when pouring hot water over them. Most of the gas released during any kind of coffee brewing is the CO2 created during roasting. While brewing filter coffee (in a V60 for example) this initial phase of degassing is called the bloom.

What makes coffee whipped?
Sugar plays a crucial role in making the super fluffy foam. Even though the surfactants in coffee serve well to help stabilize bubbles while you’re foaming the liquid, they aren’t strong enough to maintain the foam. Instead, gravity will pull the liquid down, air bubbles float up and air bubbles merge together.
