“One press of a button for 3 different milk preparations” is the promise of the feature list on Nespresso’s own page, and in the Amazon product text you choose between hot foam, cold foam and hot milk “with just one press of a button”. That sounds like three button settings. The instruction manual shows two, plus an attachment that you either put into the jug before starting or leave out.
The frother stands on its own base and runs on mains power. At Nespresso Germany it costs approx. €79 in black as well as in white (as of September 2026). On Amazon.de the catalogue showed the same figure on 7 September. Of the four devices that we compare further down from our milk frother category, it is the narrowest and the lightest. The only clue to the age of the product line comes from the manual: the PDF that the product page links to today carries 2 May 2014 as its typesetting date.
In detail: button for the temperature, whisk for the foam
In the manual the button is called the start/stop button, and in the product photo it sits in the lower part of the ribbed body. A short press starts a hot preparation, the button lights red, and after about 70 to 80 seconds the preparation is done. If you hold it for about 2 seconds, it lights blue and the Aeroccino works cold, for around 60 seconds. You put the lid on beforehand and leave it on: if it is removed during preparation, scalding can occur, according to the product page.
For foam or milk there are two attachments, which are named more clearly in the English parts overview than in the German one: a mixer for hot milk and a frothing whisk for milk foam. The illustrated instructions show the whisk as a ring that is pushed onto the mixer. With the whisk you get foam, hot or cold depending on the button press. Without the whisk and after a short press, the milk is only heated. Cold and without the whisk does not appear in any of the three recipes that Nespresso lists on the product page.
Nespresso describes how the foam turns out with adjectives, and not even identically in both places: in the feature list of the product page it is light and silky, in the description text light and airy. Switching to denser foam is not provided for. The same page also says that the Aeroccino prepares its foam “within a few seconds, without noise or vibration”. There is no decibel figure for the second half of the sentence, and the timings on the same page, which lie between 60 and 80 seconds, do not fit the first half.
Nine centimetres wide, no handle
Nespresso gives 9 centimetres in diameter and 17 centimetres in height, plus 450 grams. After converting from inches and pounds, the Amazon catalogue arrives at exactly the same values, which suggests that both sources mean the device itself and not the packaging.
The product photo shows a cylindrical body with horizontal ribs, a silver ring with the Nespresso lettering on top, and the lid on that. Nothing protrudes at the side, neither a handle nor a pouring lip. The widest point is therefore probably the round base, which in the picture projects a little beyond the body. The manual allows operation only with the supplied base.
The parts overview in the manual comes to eight items. The lid comes with a sealing ring and a so-called attachment container; then there are the start/stop button, the jug, the two attachments and the base. In this overview the jug itself is called a milk frother, and elsewhere in the same document a milk jug.
Which version exactly is in the box is less clear than the name suggests. The linked manual describes model 3594. In the embedded data of the German product page, however, the black item carries the number 3694 and the addition “Refresh”; neither is visible on the page itself. Nespresso does not explain anywhere how the Refresh version differs from the 3594, but still links the manual for number 3594 for the current item.
Is one fill enough for two cappuccinos?
For two cappuccino cups, yes; for two latte macchiato glasses, no. The illustrated instructions in the manual show it without words: one fill with the whisk fitted gives two cappuccino cups or one latte macchiato glass, and one fill without the whisk gives one glass.
The millilitres for this are in the description text of the product page: at most 120 for milk foam and at most 240 for heating. The data block of the same page says only “Capacity 120 ml”, and anyone who reads only there takes the Aeroccino 3 for a device with a single fill limit. It has two. The manual explicitly mentions two fill marks in the jug, and depending on the attachment one or the other applies.
Both values refer to the milk poured in. How high the foam rises from 120 millilitres cannot be read from any Nespresso source. For planning your morning, we therefore consider the cup figure in the illustrated instructions the more useful measure.
If three people want a cappuccino in the morning, that is two batches. Two batches of hot foam take 140 to 160 seconds together according to the manufacturer, not counting refilling and the cleaning described in the section further down.
The milk: cold yes, on fat content three answers
On temperature all Nespresso texts agree: 4 to 6 °C, fridge-cold, as the manual puts it. The product page recommends chilled UHT milk or pasteurised milk.
On fat content the versions diverge. The product page says low-fat or semi-skimmed. The tip in the German manual recommends skimmed or half-fat milk, and the same tip in English says whole or semi skimmed, that is, whole milk or semi-skimmed. The German troubleshooting section in turn advises whole or low-fat milk when the foam deteriorates. Skimmed milk and whole milk lie at opposite ends of the scale. The only level common to all versions is the middle one, which is called “teilentrahmt” or “fettarm” on German supermarket shelves and has 1.5 to 1.8 per cent fat under EU law. That is the one we would use. What fat content changes when frothing is explained in our guide How to froth milk.
According to the product page, fortified milk, reconstituted milk powder and flavoured milk are expressly unsuitable.
Cleaning: soft cloth, dry underside
The fifth operating step in the manual begins with “Cleaning after every use”. Only a soft cloth is allowed, never a brush or an abrasive sponge. The instructions call the jug waterproof and immediately add: “Do not clean in the dishwasher.” The picture sequence for the same step shows the procedure: lift the jug off the base, remove the lid with sealing ring and whisk, wipe the inside with a cloth.
Waterproof does not mean submersible. The product page demands: “Do not immerse the device or the base in water or other liquids.” For the base the manual even says “never” and justifies it by the danger of combining electricity and water, which can cause fatal electric shocks. Before cleaning, the mains plug is pulled, and it must be dry before the device is used again.
Nespresso takes the underside just as seriously. A warning in the manual requires the underside of the milk jug to be dry and names electric shock and fire as the danger. The product page extends this to the area under the base, in particular the connection area, and warns against spilling anything on the connector. If the Aeroccino has been dropped, it should according to the same page not be used any further, because water can get into the electrical compartment through fine cracks.
Aeroccino 3 or one of the three alternatives?
| Model | The difference | Price | Our rating | Choose this if |
|---|---|---|---|---|
| Nespresso Aeroccino 3 (this one) | Three preparations via one button and an interchangeable attachment | approx. €79 | 8.4 | one kind of foam is enough for you and you wipe out by hand after every batch |
| Nespresso Aeroccino 4 | A second, denser kind of hot foam, dishwasher safe according to Nespresso | approx. €89 | 8.7 | you alternate between cappuccino and latte macchiato or want to put the parts in the machine |
| Philips SENSEO Milk Twister CA6500/60 | Also 120 ml of milk, Philips gives approx. 74 °C as the milk temperature | approx. €39 | 8.4 | you need foam for two cups at most and want to save on the device |
| Severin SM 3587 Induktion | Foam up to 350 ml, milk up to 700 ml, temperature selectable from 45 to 65 °C | approx. €114 | 9.4 | you want to froth more than 120 ml of milk per batch and have room for a much larger device |
The rating ranks the manufacturer’s figures for the four devices alone; no measurements of our own are included. The prices are guide values from September 2026.
When the Aeroccino 3 fits and when another device does
Quantity first. The limit from the section on the fill lies at two cappuccinos per batch. If a third milk drink is added every morning, we would advise the Severin SM 3587, which according to Severin froths almost three times as much milk at once and costs €35 more in our comparison. According to the data sheet, however, it measures 19.5 by 15.5 by 25 centimetres, while the Aeroccino manages with a fraction of that.
Then the dishwasher. According to Nespresso, the Aeroccino 4 may go in the machine with all parts except the base at a maximum of 70 °C and costs €10 more. For the same extra cost you also get the second kind of hot foam there, which its manual lists as dense foam for latte macchiato, alongside the airy one for cappuccino. With the Severin, according to the manufacturer, the milk container, stirring inserts and lid may go in the dishwasher.
On budget the sums look different. The Philips SENSEO Milk Twister CA6500/60 costs €40 less in our comparison; Philips also designs it for 120 millilitres of milk and foam for two cappuccinos, and allows 130 seconds for frothing. On the dishwasher, however, the Philips sources contradict each other: the German instructions exclude it for the heating base, milk jug and lid, while the data sheet calls the device dishwasher safe.
If you want to set the milk temperature yourself, you will find no setting for it on the Aeroccino 3, but you will on the Severin.
That leaves the placement. The manual never wants the Aeroccino on or next to a hot surface and lists radiators, hobs, gas cookers, open flames or similar, and the product page allows it for indoor use only. If the cable does not reach the socket, Nespresso permits only an earthed extension cable with a conductor cross-section of at least 1.5 square millimetres. For longer cables, the product page sets three conditions: the electrical rating must be at least that of the device, the cable must be earthed and three-core, and it must not hang over tables or worktops.
What Nespresso does not state
Neither the product page nor the manual answers what the jug, lid, sealing ring, mixer, whisk and base are made of. Also left open are the cable length, the dimensions of the base on its own, a minimum fill quantity in millilitres, and the temperature that hot milk finally reaches. For the automatic switch-off, which Nespresso justifies with saving energy, neither the timing nor the consumption afterwards is known. Separate times for hot foam and hot milk are stated nowhere, nor is a descaling recommendation, the country of manufacture or the year of market launch. Instead of a list of what is included in the box, the manual has only the parts overview with its eight items.
Who is it for?
For a private household, and only for that. According to the product page the device is “intended exclusively for household use”, and it lists where it must not be used: in staff kitchens of shops, offices or work environments, on farms, in hotels, motels or similar residential environments, and in bed-and-breakfast establishments. The older manual listed almost the same places as intended use, namely staff kitchens, shops, offices and other work environments, farms, and use by guests in hotels, motels and other accommodation. We go by the product page that Nespresso publishes today. For the tea kitchen in the office or breakfast in a guesthouse, the Aeroccino 3 is therefore the wrong purchase.
Even in a private household the product page sets conditions. Children aged 8 and over, as well as people with reduced physical, sensory or mental capabilities or a lack of experience, may use the device only under supervision and after instruction in safe use. Cleaning and maintenance by children are allowed only if they are over 8 and supervised, and the device and its cable must be kept out of reach of children under 8. During operation the Aeroccino must never be left unattended, not even for the roughly one minute of cold foam.
