What Is Milk Frothing? What Does A Milk Frother Do?

Milk frothing is the process of turning milk into a foamy consistency using a milk frother. This is typically done by heating the milk and using a steam wand to create bubbles. The result is a creamy, rich foam that can be used to top off coffee drinks or create latte art.

Have you ever sipped into a coffee cup and wondered why the coffee tasted too delectable and soft, exactly like the taste of whip cream?

Well, the reason is, more or less all famous coffees are made of frothed milk – which has been created through employing the use of specialized equipment called ‘milk frothers’.

A good quality Milk Frother will allow users to transform liquid milk into the lovely whipped cream-like foam for their favorite hot beverages such as lattes cappuccinos etc.; adding both richness in terms of flavor & texture whilst elevating presentation with professional-looking ‘latte art’ patterns on top.

In this article, we explore everything there is known about Milk Frothing starting from its history, and how it works right through tips tricks & techniques so that you can become your home barista!

What Is Milk Frothing?

Milk Frothing can be defined as the process of transforming liquid milk into a creamy, textured foam – which can be used to top off hot drinks such as lattes, cappuccinos, and mochas or for creating artistic designs on the surface. 

A question might have come to your mind. That is, why froth milk when you can consume it raw? Actually, when you’re planning to make a cup of cappuccino or maybe a rich cup of latte, you won’t be able to do that without frothed milk. A typical cup of milk won’t be going to give you the same vibe as frothed milk. Even if you end up making a cup, that will taste so modest. We usually use frothed milk in cappuccinos or the latte to eliminate this very problem.

The process of milk frothing isn’t that complex. It usually forces the water vapor and air to mix with the milk. This creates tiny bubbles throughout the whole batch of milk, and eventually, the molecules get detached from each other.

If you ever look at the protein chains of milk, you will be lucky enough to glimpse two ends into one molecule. One is hydrophilic (prehensile to water), and the other is hydrophobic (nonprehensile to water). The air vapor enters and breaks the protein chain, and as the two ends are diverse, the entire arrangement gets detached from each other. 

However, this elementary chemical reaction provides a thick and foam-like version of milk. Assuming that you do not have any further confusion regarding the question, what is milk frothing? If yes, we can jump into our subsequent discussion. So, fasten your seatbelts and get ready! 

The History Of Milk Frothing

The history of milk frothing can be traced back to the 16th century. It was during this time that a popular beverage known as caffè latte began to gain popularity in Italy.

This coffee drink consisted of espresso and steamed milk, and it quickly became a favorite among Italians. In the years that followed, the caffè latte made its way to other parts of Europe and eventually to America.

While the caffè latte was originally made by simply mixing espresso and steamed milk together, it wasn’t long before people began to experiment with different ways of preparing this drink. By the early 20th century, two new methods of making caffè latte had emerged: the caffè latte macchiato and the caffè latte con Panna. While these two drinks were certainly delicious, they paled in comparison to the caffè latte we know and love today.

It wasn’t until the late 20th century that people began to experiment with different ways of frothing milk, and it wasn’t until the 21st century that the art of latte art began to take hold.

What Does A Milk Frother Do?

As we already know about milk frothing, now it’s time to discuss milk frothing. What is a milk frother? Can you assume? Exactly!

The machine that makes milk foam is called a milk frother. A milk frother is a well-known kitchen appliance that turns typical kinds of milk into a whipped and thick one. And later on, we use all this thick milk in any coffee (latte, cappuccino). 

Milk frothers could be of many types—either handheld or battery-powered. Even in recent times, electric-powered milk frothers’ are also widespread in the market. But whatever it is, whether you use a handheld milk frother or a battery-powered one, the machine will always render you with a bunch of creamy and thick milk. And this is the main objective of using a milk frother. 

We often get asked, how to make milk foam at home. This question is utterly surreal in this technological era where you can easily afford appliances by spending some bucks. However, in places where milk frother is unavailable, you can get your job done manually. But using a milk frother for frothing milk is always the best option.

Nonetheless, you might have been wondering what a frother does, is it? Well, a milk frother pours the air into the milk. In other words, it aerates the milk and forms some tiny microbubbles. As well as increasing the overall volume of milk. The airing process varies from machine to machine as they come in different shapes and dimensions.

How To Make Picture-Perfect Froth At Home

Ah, frothed milk. The finishing touch on a perfect cup of coffee. It’s the stuff of Instagram and barista dreams. But what if I told you that you don’t need fancy equipment or years of practice to make beautiful, delicious frothed milk at home? With this trusty guide, you’ll be a foam-making pro in no time!

What You’ll Need:

  • A milk frother
  • Whole milk (2% or higher)
  • A microwave-safe mug or glass jar
  • A stovetop pot (optional)
  • A spoon or whisk (optional)
  • Your favorite coffee beverage (obviously)


  1. Pour milk into your mug or glass jar. If you’re using a mug, make sure to leave some room at the top for frothing
  2. Insert the frothing wand of your milk frother into the milk
  3. Turn on the frother and hold it just below the surface of the milk
  4. Slowly move the frother up and down until the milk is foamy and doubled in size

Important: It’s fine to microwave your milk before or after frothing. Microwave the milk for 20-30 seconds, or until it’s hot to the touch. Alternatively, you can heat the milk on the stovetop over low heat until it’s hot.

Spoon the frothed milk over your coffee and enjoy!

What Milk To Use For Frothing?

Let’s get you to some science lessons. You already know about the “behind the scene” of milk frothing. Let’s be a bit more precise. The thickness of frothed milk leans on the protein and fat percentage of milk we are using. In that sense, whole milk (full-cream milk) possesses a tremendous amount of protein and fat than any other milk. In the bargain, non-dairy milk holds nearly less protein and fat percentage. 

Following this very situation, isn’t it wise to use whole milk for frothing? Yes, it is. From all the way! 

A batch of whole full-cream milk will provide you with fabulous, creamy, and thick-frothed milk that you can use later on in coffee or other drinks. But, choosing non-dairy milk (almond milk, soy milk) would do the opposite and is not worthy of being frothed.

What Milk Makes The Best Froth?

Imagine a scenario; in which you got a bunch of different kinds of milk. There is dairy (cow milk, whole milk) and non-dairy (almond milk, soya milk) milk in the batch. Now, if you plan to make a cup of delicate and rich cappuccino or latte, which milk would you prefer to froth? 

The answer is simple. Firstly, all you have to do is look forward to the milk’s chemical properties. As in the fat and protein percentage of the milk. In terms of this percentage, dairy-sourced milk will be going to give you a good cut. They are high in proteins and fat. There’s no better option to froth than going for dairy-sourced milk. 

On the other hand, low-fat or skim milk could also be better. They provide an enormous amount of tiny bubbles throughout the whole batch of milk and make the latte cup more delicate and prosperous than ever before. 

Everything seems good, isn’t it? Well, there’s a massive inconvenience that most people refuse to say. Whole full-cream milk contains a substance along with protein and fat. That is “casein.” It’s a solid amorphous essence that refrains the foam from getting intact for a long time. Implies, less the casein percentage, more creamy and foamed drink. A typical batch of cow milk contains 3% casein in it

Which one to choose then? Well, if you’re looking for something delicate and rich and want the coffee cup to look good, you can go for the non-dairy-sourced milk. But, if you prefer taste over the aesthetics, we recommend using whole milk

What Else Can You Do With A Milk Frother?

You might think that we use a milk frother to make the volume of the milk more enormous and add a creamy texture to it. Yes, we do that using a milk frother, and this is the main objective of using this very appliance. However, we can use a milk frother in many ways besides only frothing milk. 

From mixing up your delicious cup of coffee and making tea varieties to assembling your breakfast, you can approach the milk frother in an across-the-board way. 

In terms of making a cup of rich and delicate latte or maybe cappuccino, you can apply the milk frother to froth the milk. This will provide you with an excellent taste boost with a specific texture. Later on, to make protein shakes or mix several types of cocktails, we can use a milk frother to get the job done quickly and way more accessible.

However, all these are assumable. You couldn’t assume that you can also make the milk frother capable while you’re making your breakfast. From scrambling eggs for breakfast to blending dips, a milk frother is usable all the way.

So, get yourself out of the borderline. And make your milk frother worthwhile and use it at every possible angle you can.

What Can You Froth Beside Milk?

As you read in the previous portion, you can use a milk frother and apply that to various applications along with frothing milk. Now, what exactly can you froth besides milk?
