How does a milk frother work? That’s the question you might be asking when you want more foam in your beverage? Be it a mug of cappuccino or chocolate milk, your love for a bubbly treat of milk never gets old. If the great foam is what you crave, then a milk frother is what you need.

A milk frother is hands down, the best invention for the coffee lover. Once you learn to use milk frothers, they open up the world of delicious lattes, cappuccinos, and, yes, latte art. So let’s get in on this action! 

What Is A Milk Frother? 

A milk frother is a utensil for frothing milk to be added to your beverage. It pushes air into the milk and bubbles it up to turn it into foam. This foaming then appears at the top of the liquid.

The frothed milk adds the richness of milk to your beverage, along with the texture you’d love.


Not only this, with a milk frother, you can:

  • Make frothed vanilla.
  • Froth up your pumpkin latte.
  • Try tea latte topped with foam.
  • Add a little twist to your aromatic cocoa.

Each frothing tool does the same thing as adding air to the milk. The added air increases the volume of the milk as a result. Due to simple functioning, frothers last long and get by with simple maintenance.

Types of Milk Frothers

The main types of frothers available in the market are:

  • Manual frothers
  • Electric, handheld frothers
  • Automatic frothers

Manual Frother

A manual frother is similar to a french press coffee maker, including a carafe and a plunger. The lid of the carafe includes a plunger, which acts as a coffee press. A hole in the top makes way for the plunger to froth the milk. The plunger has a mesh screen at its bottom.

It is human-powered, often inexpensive, and easy to use. Since it has only a plunger and a carafe, there’s no need to doubt its durability. In case you have a glass carafe, make sure that it doesn’t fall off.   

*/ Working

  1. a) Heat the milk. Put it inside the carafe and close the lid.
  2. b) Move the plunger up and down. This to-and-fro movement of the plunger will create foam in the milk.
  3. c) Repeat the process until you achieve the desired consistency.
  4. a) With just a few presses of the plunger, you can double the milk volume within no time.

Electric, Handheld Frother

The handheld frother comes with a stainless steel whisk and a solid rubber grip. It is electrically powered and looks very similar to a handheld blender.

It is portable, light-weight, and easy to operate. You don’t need to warm the milk before frothing as it foams both hot and cold milk. It would help if you were careful enough not to use the electric frother for extended times. This might result in decreased efficiency.  

You will also need a large vessel to prevent the milk droplets from creating a mess while frothing.

*/ Working: 

  1. a) Take a jar and put some milk in it.
  2. b) Press the button located on the side of the frother’s grip to turn it on. The wand will keep on working as long as you hold the button.
  3. c) Put the whisk inside the vessel and move it up and down. The whisk acts as a propeller and aerates the milk.
  4. d) Follow this process until the required foam is formed.

Automatic Milk Frother

An automatic milk frother has a similar appearance to the conventional electric kettle. It comes in various sizes, shapes, adjustable temperature facilities, and foam density. Also, it is automatic, runs on electricity, and requires no manual labor. Likewise, you don’t need extra skill to operate it. This makes it the most suitable product to use as a frother. 


*/ Working

  1. a) Remove the lid of the frother and add some milk to it.
  2. b) Close the lid and turn the switch on. This will heat the milk and start producing foam at the top.
  3. c) After a few moments, turn the switch off. Foamy milk is ready to enjoy.

Type of Milk To Use:

As for the temperature for warm frothing, stop heating the milk around 135 to 145°F. Because even after you stop warming it, the milk’s temperature with high-fat content will keep on rising by around 10°F. This will make the milk taste awful. That’s why it’s best (especially for beginners) to use skimmed milk.

Skimmed milk gives the best bubbly layer of foam and a nice texture due to its lower fat content. Also, its temperature doesn’t rise after you’ve stopped heating it.  


135°F is the ideal temperature for warm frothing. Anything more generous than that is going to break the milk protein bonds and burn your milk.

But when it comes to cold beverages, warm frothing is not an option. Instead, try cold frothing. When cold-blended with milk frothers, the milk makes a robust microfoam that adds a lively beverage taste.
