How Does a Nespresso Machine Work?

Nespresso machines are known for their ease of use. Add water, insert a pod, press a button, and you’re all done. But, there’s a little more to how Nespresso machines work.

Nespresso machines come in two versions: OriginalLine and VertuoLine. OriginalLine uses one-touch pod technology, while VertuoLine uses centrifugal technology that spins the pod 7,000 times per minute.

I’ve used both kinds of Nespresso coffee machines, and today I’ll go into detail about how they work. I’ll also explain what you should know about Nespresso pods and what kind of drinks these machines brew.

How Nespresso Machines Work

Every coffee machine needs water and coffee. But these two components are used differently in different coffee-making processes. For example, there’s immersion brewing, where ground coffee is soaked in water in a French Press.

There are pour-overs where the water is poured over the coffee grounds and then drips through them. And, of course, there’s espresso, where hot water is forced through a tightly packed bed of coffee grounds at high pressure.

Nespresso machines work differently. Most importantly, they use a pod system and pressure or centrifugal technology to extract coffee from Nespresso pods. 

Each Nespresso machine has a water tank that you fill with cold water. A heating element inside the device warms the water before it’s pushed through the coffee pod at high pressure.

However, the extraction method differs in two kinds of Nespresso machines.

Nespresso OriginalLine

OriginalLine Nespresso machines use a 19-bar pressure pump to extract espresso. 

You start by filling up the water tank. When you turn on the machine, the heating element warms the water in seconds, so it’s the optimal temperature for the best extraction. The machine is ready to brew when it’s done flashing. Then you insert a coffee pod into the pod holder and close it. Press a button corresponding to the drink you want to make. 

The Nespresso machine forces the heated water from the reservoir into the machine via a pump. The machine pierces three tiny holes in the top of the pod, so the water can drip through the pod and mix with the ground coffee inside.

The water is forced through the pod at 19 bars of pressure via an ultra-thin tube. Brewed coffee comes out on the other end of the coffee capsules into your cup. Nespresso pods have a filter inside that ensures no coffee grounds get into your cup.

Once the coffee has been extracted, the machine forces air through the pipes to make sure there’s no more coffee left. Once this is done, the Nespresso machine is immediately ready to brew another cup of coffee without any leftover ground coffee from the previous cup.

Finally, Nespresso machines have a lever mechanism that transfers the pod into a built-in waste basket, so you don’t have to throw away the pod straight away.

Nespresso VertuoLine

Nespresso came up with VertuoLine coffee machines in 2014 to satisfy the demand for larger coffee drinks, mostly in the US market. This is also a pod-based system, but VertuoLine machines use different coffee pods that are larger and bowl-shaped.

An important difference between OriginalLine and VertuoLine is the brewing technology they use. VertuoLine machines use patented Nespresso centrifusion technology, which is a combination of centrifugal and infusion. The name describes the movement of the pod during extraction.

VertuoLine machines are even easier to use than OriginalLine, thanks to the centrifusion technology. You don’t need to press a button to choose the drink size. Instead, every Vertuo capsule comes with a barcode. You insert the capsule into the pod holder and close it.

The machine automatically reads the barcode and optimizes all brewing parameters for that particular type of coffee — it adjusts the water volume, brewing temperature, and flow rate. 

The coffee machine injects a small amount of water into the top of the bowl-shaped pod, and the pod spins 7,000 times a minute to infuse ground coffee with water. This results in a thicker crema compared to OriginalLine models.

To sum up, VertuoLine uses a centrifugal system while OriginalLine uses a pressure-based one. You can make larger cups of coffee with a VertuoLine coffee machine — up to 14 oz.

How to Use a Nespresso Machine

Here’s how to use a Nespresso OriginalLine machine:

  1. Plug in the machine
  2. Fill the water tank
  3. Place the cup on the drinks tray below the coffee spout.
  4. Press the button to turn on the machine. The button will flash, showing the machine is warming up. You can use the machine once it stops flashing.
  5. Insert the pod into the pod holder and close it.
  6. The Nespresso machine will puncture the foil-covered size with three prongs.
  7. Press the button corresponding to the size of the coffee drink. The machine will push water from the tank through a line that goes around the heating element. Water goes through the capsule at 19 bars of pressure.
  8. The machine makes a delicious coffee drink.

You can also customize the amount of hot water in your drink. You do this by inserting the pod and holding down the required brew button. Release the button when the amount of coffee you want is done brewing. The coffee maker will remember your preference and dispense this amount of water every time.

Nespresso requires maintenance, just like a traditional espresso machine. You should descale the OriginalLine device around every 100 cups. This will prevent the build-up of bacteria and limescale. You also have to remove the spent capsules from the capsule container. 

Here’s how to use a Vertuo machine:

  1. Plug it in and switch on
  2. Fill the water tank
  3. Place the cup on the drinks tray
  4. Turn the lever to unlock the coffee maker and lift the head to insert the pod.
  5. Insert the pod dome side down and close the lid.
  6. The machine automatically reads the barcode on the pod and optimizes the brewing parameters.
  7. The machine inserts water into the top of the pod and spins it 7,000 times per minute.
  8. The centrifugal system pushes water through several punctures along the pod’s edge. 
  9. When the machine is done brewing, turn the lever to unlock again, so the machine moves the pod into the waste bin.

Vertuo device also has to be maintained the same as OriginalLine. You should occasionally descale it and empty the used pods’ container.

Nespresso Coffee Pods

You need pods to use Nespresso coffee machines. A pod is a small coffee container made from aluminum. It’s hermetically sealed, which means it’s airtight, so the coffee inside the pod stays fresh.

The pods are available directly from Nespresso on their website or through other major stores and retailers, such as Amazon. Nespresso has a large range of pods, from single-origin to flavored capsules. There are also seasonal and special releases throughout the year.

Nespresso used to hold a patent as the sole manufacturer of OriginalLine pods, but that changed after Nespresso owner Nestle lost a patent lawsuit in 2013. Nowadays, there are many other brands that sell ground coffee beans in pods.

These are compatible with OriginalLine. Nespresso still has the patent for VertuoLine pods, so you can get Vertuo coffee capsules only directly from them.

Keep in mind, there are two kinds of pods: for OriginalLine and VertuoLine machines, and they aren’t cross-compatible. In other words, if you buy a Vertuo pod but you have an OriginalLine device, you can’t use it.

OriginalLine Nespresso pods have a cylinder shape with a dome top. VertuoLine pods are bowl or dome-shaped and are a half-circle. 

Vertuo pods have a barcode that the machine reads and automatically adjusts the parameters. This is an advantage over other one-button brewers that only have one brewing mode. Nespresso recognizes that different coffee drinks need different coffee-to-water ratios.

Drink Options with a Nespresso Machine

Nespresso OriginalLine machines are specifically made for espresso. They can brew:

  • Ristretto — Uses the least amount of water out of the three coffee options. It’s very concentrated, and it gives a 0.84 oz shot.
  • Espresso — Makes espresso like a typical espresso machine. Gives a 1.35 oz of espresso.
  • Lungo — Means long. Gives 3.72 oz of espresso because it uses a large amount of water. Out of the three, lungo is the most similar to an Americano.

Note: Some older OriginalLine Nespresso machines, such as Citiz and Pixie, only have espresso and lungo options.

VertuoLine devices are newer, and they have more coffee options. A Vertuo machine makes ristretto, espresso, and lungo and has options for drip coffee. Also, there’s a Vertuo Latissima line, which comes with a milk frother, so you can make milk-based espresso drinks, such as latte, cappuccino, macchiato, and flat white, by pressing a button on the coffee maker.

Frequently Asked Questions (FAQ)

How to tell if a Nespresso machine is VertuoLine or OriginalLine?

How does a Nespresso machine brew coffee?

A Nespresso machine uses pods to brew coffee, and Nespresso OriginalLine machines force hot water through the pod using 15 bars of pressure to brew in 30 seconds. Meanwhile, Nespresso VertuoLine machines use centrifusion technology, which spins the pod at 7,000 rpm to extract coffee.

Nespresso Machines: Final Thoughts

Both Nespresso Original and Vertuo devices will make a flavorful cup of coffee. The question is, what particular coffee do you like? If you’re more of an espresso fan, go for an OriginalLine. But, if you like a larger cup of coffee, VertuoLine is the device for you.
