verse koffie koffie met melk cappuccino

A good cappuccino isn’t just about fresh coffee, but also the right milk. The type of milk determines whether your foam will be sturdy and creamy, or thin and airy. Whether you go for whole milk or prefer a plant-based alternative like oat milk: the choice affects the flavour, the structure AND your coffee experience. Here you’ll learn which milk works best for your perfect cappuccino, whether you’re a barista or a home coffee lover.

What makes milk suitable for a cappuccino?

Not every milk is equally suitable for frothing. The secret of a good cappuccino lies in the balance between flavour and texture. And that’s largely determined by the fat and protein content of the milk.

Milk with enough fat gives a full, creamy flavour — exactly what you’re after in a cappuccino. Think of that soft mouthfeel that pairs perfectly with the strength of espresso. At the same time, milk proteins create the airy, stable foam layer. The more proteins, the easier it is to get firm foam that doesn’t collapse straight away.

Temperature is also important. Cold milk froths better than lukewarm milk, so always start with milk straight from the fridge. While frothing, heat the milk ideally to 60 to 70 degrees Celsius. Warmer than that? Then you scorch the milk and lose the sweet flavour so characteristic of a good cappuccino.

Which types of milk can you use for a cappuccino?

There are surprisingly many types of milk you can use for your cappuccino. Each type gives its own flavour and foam texture. Whether you love a full, creamy cappuccino or a lighter version with plant-based milk.

Whole milk – creamy and classic

Whole milk is the favourite choice of many baristas. Why? Thanks to the higher fat content (around 3.5%) you get a lovely full flavour AND a velvety foam layer. The foam is stable, glossy and perfect for latte art. Ideal if you love a classic cappuccino.

Semi-skimmed and skimmed milk – lighter but still froth-friendly

Semi-skimmed milk has slightly less fat (around 1.5%) but still enough protein to make a nice foam. The result is a cappuccino with a slightly fresher flavour and lighter foam. Skimmed milk (0% fat) froths even more easily, but lacks that creamy body. Handy if you’re watching the calories, but not the favourite when it comes to flavour.

Special barista milk – the barista choice

Some supermarkets sell ‘barista milk’ or ‘frothing milk’. These are specially developed with adjusted protein and fat content for extra stable foam. Perfect if you often make cappuccino at home and always want the same result. They froth easily and give a full, consistent flavour.

Plant-based milk – cappuccino without dairy

Prefer no cow’s milk? Then there are plenty of plant-based options! Think:

  • Oat milk: creamy, lightly sweet and froths surprisingly well. Many baristas swear by it.
  • Soy milk: lots of protein, so good foam. Flavour is a bit more neutral.
  • Almond milk: airy, but often tricky to get stable foam. Has a lovely nutty flavour though.
  • Coconut milk or rice milk: less protein, so foam is tricky, but with a pronounced flavour.

Preferably go for versions labelled ‘barista edition’. Those are specifically made to froth and work better with hot espresso.

Tips for frothing your milk at home

A cappuccino with a beautiful, creamy foam layer starts with proper frothing. Whether you have a steam wand, an electric milk frother or just a whisk: with these tips you’ll get the most out of your milk.

Step 1. Start with cold milk

Cold milk (straight from the fridge) froths best. Warm or lukewarm milk barely froths because the protein structure has already partly broken down.

Step 2. Use the right amount of milk

Fill your frother or jug to about 1/3. Milk expands while frothing, so you need room for the foam.

Step 3. Pay attention to temperature

The ideal temperature for frothed milk is between 60 and 70°C. Milk getting warmer than 75°C? Then it scorches.

Step 4. Use the right technique

  • With a steam wand: hold the nozzle just under the surface for airy foam, then push it deeper to mix the foam.
  • With an electric frother: choose the “warm milk with foam” setting or a cappuccino icon.
  • By hand: heat the milk and whisk with a balloon whisk or use a milk whisk until you see foam.

Step 5. Let the milk rest briefly

After frothing, you can gently swirl the milk in the jug. That gets rid of big bubbles and gives you a lovely, smooth foam structure.

Extra tip: always use a milk with enough proteins, whether you go for dairy or plant-based milk. No proteins = no foam!

Frequently asked questions about milk for your cappuccino
What is the best milk for frothing?
Whole milk remains a favourite among baristas due to its rich flavour and stable foam. However, barista oat milk also performs excellently. It is important that the milk contains enough protein and is well chilled.
Why isn’t my milk frothing properly?
The milk may be too warm at the start. A second problem could be that there are too few proteins in the milk. Finally, you may be using the wrong frothing technique or device. Choose milk with at least 3g of protein per 100ml and make sure you froth up to a maximum of 70°C.
Can I make a cappuccino with oat milk?
Absolutely! Especially the barista editions of oat milk foam up well and provide a full, slightly sweet flavour. Perfect if you prefer not to use cow’s milk but still want to enjoy a robust cappuccino.
How long can you keep frothed milk?
Actually, no. You get the best foam when you froth milk just before use. After a few minutes, the foam starts to collapse and loses its texture. Cappuccino is simply at its best when fresh!
