Nespresso Aeroccino 4 overview

Nespresso Machines are known for their practical and exquisite nature. So it’s no wonder that they’ve developed several accessories for their machines in an attempt to replicate the success they’ve had with their well-known espresso machines.

Probably you’re thinking about how come your morning will start without an Instagram-worthy latte art? For this, you’ll need a milk frother that makes your coffee divine.

To target that, Nespresso introduced its electric milk frother, so it became the significant other of its capsule espresso machine. Nespresso milk frother lineup includes Aeroccino Plus (a discontinued model), the Aeroccino 3, and the upgraded add-on, the Aeroccino 4.

Nespresso Aeroccino 4 buttons have four easy yet varied milk settings:

  • Cold Macchiato
  • Hot Milk
  • Cappuccino (warm and airy milk foam)
  • Latte Macchiato (warm and dense milk foam)

It crowned your coffee with a creamy foam in a matter of seconds. The best part of Aeroccino 4 is that its system operates in silence, making it ideal for producing coffee when you wake up early and don’t want to wake your family.

  2. Offers you 4 milk settings including the cold one.
  3. Doesn’t make noise.
  4. Dishwasher safe and easy to clean.


  1. Aesthetics aren’t up to mark.
  2. Less capacity.
  3. Pricey.
  4. It doesn’t come up with a non-metal spoon.

Things to consider before buying Nespresso Aeroccino 4 Milk Frother

Overall Design

Nespresso Aeroccino 4 is manufactured with a lot of care and thought processes. It squeezes on your kitchen counter due to its nominal dimensions (WxDxH) of 7.1 x 7.1 x 8.3 Inches. This electric milk frother comes with a chrome jug, a clear lid, a whisk, a connector base, and a seal.

Its spout on the front makes the pouring easier and prevents you from messing up. Its ergonomic handle makes the grip safer than ever. In addition to this, Aeroccino 4 works like a flask, which means that it isn’t hot from the outside, and you can easily grasp it.

Not just these, the spring inside the Nespresso Aeroccino 4 stays in it whether you’re heating or frothing the milk. The whisk is magnetic, which means that it will readily stick to the bottom connector when you place the chrome jug on it.

Its four-button interface makes it easy-peezy to use. It weighs just 2.2lbs, so it’s easily portable which illustrates that if you want to go camping, just put the Nespresso Aeroccino 4 in your bag with other important items, and there you go.

It has stainless steel and a rigid plastic outer casing. But I find the look of the Nespresso Aeroccino 4 a bit old-fashioned as it does not match the vibe of a modern kitchen. Because Nespresso is famous for its sleek yet modish look, we expect something extraordinary in its stature as well. Well, other than this, I find this as my perfect partner.


I’ve tried and tested the Aeroccino 4 milk frother and noticed a few things while using it.

Okay, so I love Latte Macchiato, and for that, I froth cow’s milk. I observed its temperature, which is 69.1°C.

Another thing that I’ve seen is that heating milk also creates a bit of foam (obviously not that dense like Cappuccino or latte), having a temperature of 62.9°C, which is less than the temperature of a Latte Macchiato setting.

As previously mentioned, its four-button interface is simple to use. You can press any button to switch on the machine (after plugging it in).

How to Use Aeroccino 4 Milk Frother

If you want to know the exact steps of using Nespresso frother, then here are the steps.

Step 1:  

Wipe the Aeroccino 4 jug with a clean and damp cloth.

Step 2:

Place the whisk spring in the correct position.

Step 3:

Fill the frother with the milk up to one of the two MAX levels. The lowest level indicator is for maximum frothing, and the highest level indicator is for heating the milk (with no froth).

Step 4:

Cover the Aeroccino with the lid and place it on the connector base.

Step 5:

Choose the preferred style of milk that your coffee requires.

Step 6:

The selected button will blink when pressed and becomes steady when the milk is ready. Also, you can stop the preparation at any time by removing the Aeroccino from the base or by pressing any button. 

Step 7:

Use a non-metal spoon to collect the foam from the Aeroccino and enjoy your favorite coffee.

Quality of Foam:

One thing is implicit about Nespresso Aeroccino 4 foam quality. It produces an excellent form than Aeroccino 3 and Barista recipe maker.

It has two foam-density which makes it more enticing to the coffee lover. For instance, if you press the Latte Macchiato setting, it creates a silky, smooth, and thick froth. When you select the Cappuccino option, it creates a lighter froth that dabs perfectly on the top of your cup. It also heats milk for things like hot chocolate by pressing the Hot Milk button. Not just that, there’s a Cold Macchiato milk setting for generating a dense and chilled out.

Note The froth formed depends on the milk’s protein content because it is the protein that clubs together to produce foam.

For that matter, you need to know the fat difference among varied kinds of milk. Like, if you use low-fat milk, dry and stiff foam is created. However, if you use high-fat milk, wet and silky foam is created. Moreover, for optimal foam use, semi-skimmed milk is chilled.

Some tips to make tremendous foam crowned on your latte are:

  • Use fresh milk and avoid using milk close to the expiry date, as it will not froth well. 
  • Use UHT (Ultra heat treatment) milk boxes for the best results.
  • Use refrigerated milk.
  • Shake the milk box so that protein is distributed evenly.
  • The best milk for frothing is cow’s milk, but you can try other kinds of milk. Like, coconut or almond milk.
  • Don’t try frozen milk as it will not froth.

Simple Programmability

Nespresso Aeroccino 4 has an automatic shutdown that turns the machine off after 9 minutes of inactivity. This function drastically cuts energy use and saves you the headache of remembering to switch it off when you’re in a hurry.

You can press any button from the four buttons to On the machine again. Apart from that, it can prepare hot and cold froth in approx 80 seconds and heating milk is done in 150 seconds.

Milk Frothing Capacity

Inside the Nespresso Arricano 4 milk frother, max lines for milk foam preparation is 120ml/4oz, and for non-foam heated milk is 240ml/8oz. This amount was sufficient to make one to two drinks.

Cleaning & Maintenance

As mentioned above, the Aeroccino 4 parts are dishwasher safe (base not included). This simplifies the cleanup process and encourages users to froth more frequently. Its cleaning manual also suggests to its users the frequent cleaning guide.

These are the steps that you need to follow for proper cleaning:

Step 1:

To initiate cleaning, detach the Aeroccino 4 jug from the connector base. Then remove the spring, whisks, seal, and lid. 

Step 2:

Either hand wash these parts with warm and mild soap, or you can place them into the dishwasher at 158°F. 

Step 3:

Do not submerge the jug and base in water, as it is not good for Aeroccino.

Step 4:

Before plugging in the Aeroccino 4, make sure its jug’s base is completely dry. 

Face Value

Nespresso Aeroccino 4 comes with a retail price of $120. Of course, it is not cheap at all, and it is included in the list of the most expensive frothers.

But it’s cost-effective because of its quality foam. And it is successfully competing with the barista-style foam. So, yes, if you want cafe art in your very own home, then it’s the best on your kitchen counter.

Is the Nespresso Aeroccino 4 milk frother worth the price?

If you want a hot latte and cappuccino, then I recommend going with the Aeroccino 4 as its milk temperature is hotter than its other counterparts. If you’re particular about foaming consistency, then yes, it is a go-to for you. This versatile, practical, and ergonomic Aeroccino is portable and produces varied drinks. Thus, you need to level up your game if you want this silent worker.

But if you want it for your family, then it lacks the milk capacity part, and you need to froth/heat the milk again and again. Furthermore, you may not like its aesthetics if you have a modern kitchen, as its design is a bit obscure, I would say. Lastly, it’s pricier than the frothers available in the market, and this is the thing that may twist your decision if your budget is tight.

Nespresso Aeroccino 3 vs. 4: which is the better frother?

Aeroccino 4 is the upgraded version of Aeroccino 3. Aeroccino 4 has more milk settings than Aeroccino 3. The earlier one uses the single whisk, and you don’t need to take that out, unlike Aeroccino 3, which has two whisks. Not just that, Aeroccino 4, with an ergonomic handle, has better quality foam than Aeroccino 3.

Why is my Nespresso Aeroccino 4 not frothing?

Reasons are filth around the magnetic whisk, loose connection to the base, burned-out copper strip, a faulty thermocouple, and much more. For more details and solutions, read our guide on how to fix Nespresso Frother.

What milk is best for frothing?

Full-cream milk or milk high in fats creates thicker and creamier foam. Whereas, low-fat milk or skimmed milk produces lighter and airier foam. It is all due to the fat content in the milk; the more the protein, the more froth.
