The world of coffee and specialty beverages has seen a significant rise in the popularity of cold foam and frothed milk in recent years. Both of these creamy toppings have become staples in many coffee shops and cafes, but the question remains: are they the same thing? In this article, we’ll delve into the world of cold foam and frothed milk, exploring their differences, similarities, and the science behind these delicious toppings.
What is Frothed Milk?
Frothed milk is a type of milk that has been aerated to create a creamy, foamy texture. This process involves heating the milk to a specific temperature, usually between 140°F and 160°F, and then using a steam wand on an espresso machine to inject air into the milk. The air bubbles get trapped in the milk, creating a thick, creamy foam that can be used as a topping for coffee drinks, hot chocolate, and other beverages.
Frothed milk is a popular topping for coffee drinks, particularly cappuccinos and lattes. It adds a rich, creamy texture and a subtle sweetness to the beverage. However, frothed milk can be finicky to work with, as it requires a specific temperature and technique to create the perfect foam.
The Science Behind Frothed Milk
The science behind frothed milk lies in the way that air bubbles interact with the milk proteins and fats. When milk is heated, the proteins and fats begin to break down and reorganize themselves. This process creates a network of molecules that can trap air bubbles, resulting in a thick, creamy foam.
The type of milk used can also affect the quality of the frothed milk. Whole milk, for example, contains more fat and protein than skim milk, making it easier to create a rich, creamy foam. However, skim milk can still be used to create a decent froth, as long as it is heated to the correct temperature and aerated properly.
What is Cold Foam?
Cold foam, on the other hand, is a type of foam that is created without heat. It is typically made by whipping heavy cream or half-and-half with a mixer or blender until it becomes stiff and holds its shape. Cold foam can be used as a topping for coffee drinks, desserts, and other sweet treats.
Cold foam has become a popular alternative to frothed milk in recent years, particularly in the world of cold brew coffee. It adds a rich, creamy texture to the beverage without the need for heat or specialized equipment.

What is cold foam and how is it made?
Cold foam is a type of topping made from milk that has been frothed and chilled to create a creamy, velvety texture. It is typically made by frothing milk using a steam wand on an espresso machine or a milk frother, and then chilling it in the refrigerator until it reaches the desired consistency.
The process of making cold foam involves frothing the milk to incorporate air and increase its volume, and then allowing it to cool and set. This process can take several hours, depending on the temperature and the desired consistency of the foam. Some coffee shops and baristas also use specialized equipment, such as cold foam dispensers, to make the process easier and faster.
What is frothed milk and how is it different from cold foam?
Frothed milk is a type of milk that has been frothed using a steam wand on an espresso machine or a milk frother. It is typically used as a topping for coffee drinks, such as cappuccinos and lattes. Frothed milk is different from cold foam in that it is not chilled and has a lighter, more airy texture.
While frothed milk is often used as a topping for hot coffee drinks, cold foam is typically used as a topping for cold coffee drinks, such as iced lattes and cold brew coffee. The texture and consistency of frothed milk are also more delicate and prone to collapse than cold foam, which is thicker and more stable.
Can I make cold foam at home?
Yes, you can make cold foam at home using a few simple ingredients and some basic equipment. You will need milk, a milk frother or steam wand on an espresso machine, and a refrigerator to chill the foam. You can also use a blender or food processor to froth the milk, although this method may not produce the same level of foam as a dedicated milk frother.
To make cold foam at home, simply froth the milk using your chosen method, and then chill it in the refrigerator until it reaches the desired consistency. You can also add flavorings, such as vanilla or cinnamon, to the milk before frothing it for added flavor.
Is cold foam healthier than frothed milk?
Cold foam and frothed milk are both made from milk, so they have similar nutritional profiles. However, cold foam may be slightly healthier than frothed milk due to its lower calorie and fat content. This is because cold foam is typically made with nonfat or low-fat milk, which has fewer calories and less fat than whole milk.
That being said, both cold foam and frothed milk can be part of a healthy diet when consumed in moderation. It’s also worth noting that some coffee shops and baristas may add large amounts of sugar or syrup to their cold foam, which can greatly increase the calorie content.
