The Inissia and CitiZ are two of Nespresso's best-known Original-line machines. Here's how they compare, and what to buy now that the Inissia has been discontinued.
The Nespresso Inissia and CitiZ are two of Nespresso’s most popular lower end models from their Original Line of machines.
Both are simple capsule machines that deliver espresso with plenty of crema at the push of a button.
“The CitiZ's bigger tank and milk frother bundle make it the better long-term machine. The Inissia was the budget way in.”
2026 update: The Inissia has been discontinued in most markets and replaced by the Essenza Mini as Nespresso's entry-level Original-line machine. The comparison below still helps if you're considering a used Inissia, but for a new purchase, think of it as Essenza Mini vs. CitiZ.
I think these two machines are best suited for small spaces, as well as office settings where minimal clean up, quick brewing and variety are top priority.
The Final Shot: The CitiZ is the top pick in this match-up for its larger water tank and the popular CitiZ & Milk bundle with an Aeroccino frother. It's a solid fit for more dedicated espresso drinkers. If you're new to Nespresso and on a smaller budget, the Essenza Mini (the Inissia's successor) is a great way to test the waters, and you can add a frother later.
I actually purchased the CitiZ a couple months ago for my office to cut down on my afternoon coffee runs. It saves me so much money (I was spending $4-5 on a latte or cappuccino every day) and time. I’m a serious fan. And so are my coworkers.
Both machines have a lot of similarities and function pretty much the same way, so understanding the feature upgrades you’ll get along with that higher price tag of the CitiZ can be tricky.
This article will break it down for you, so you can pick the best Nespresso machine for your coffee needs.

Both the Inissia and the CitiZ are designed to function the same way, using the Nespresso capsule system, comprised of a wide selection of “grand crus” that include a range of flavors and strengths for single serving espresso shots.
The Nespresso capsules are specifically manufactured, sized and hermetically sealed with both pod and lid made in recyclable aluminum lined in food grade lacquer. These capsules are easily inserted and just as easily ejected from both machines.
It’s sort of a drop and pop system and could not be easier.
The aluminum capsules are recyclable, and Nespresso runs free recycling programs with prepaid bags and drop-off points in many areas. That was a big factor for me when deciding on a capsule system.
Each Original-line capsule contains about 5–6 grams of finely ground coffee. Nespresso offers dozens of blends and single origins made from Arabica, Robusta or a combination. Arabica tends to be smoother and sweeter, while Robusta adds body, bitterness and extra caffeine. Learn more in our guide to Arabica vs. Robusta.
Nespresso also releases limited-edition and seasonal coffees throughout the year.
Each capsule can produce either an espresso shot of 40ml or a lungo (long) 110ml cup by using the one touch programming that is the same on both machines. You literally push a button to select your preference and the machine brews.
If you want to fill up a taller travel mug the drip filter on both models folds up to allow the mug to fit easily under the pourer.
The crema is also really nice across the board with Nespresso system and was one of the things I was impressed by right away.
Both machines use a 19-bar pump. That's the pump's maximum rating; what matters is that it delivers enough pressure through the capsule to produce consistent shots with good crema.
With a fast 25-second heat-up, there's no time wasted waiting to brew. You also don't have to remember to power them off, since both machines shut off automatically after 9 minutes of inactivity.
Both the Inissia and the CitiZ have used capsule containers that will hold about 11 used grand crus, depending a little on how they shake out in there. I usually empty mine about once a week, depending on how much I’m drinking.
The Inissia and CitiZ are both from the lower end of the Nespresso range of machines, so they share a lot of similarities when it comes to overall functionality and customization.
Where they differ is in regard to some of the bonus features that the CitiZ offers, as well as the overall size and design.
I would describe the Inissia as a fun, funky little machine. It comes in an array of colors, including, black, red, silver, white, and titan so that you can choose one to blend in to your décor or stand out on the counter.
The Inissia operates with an ergonomically designed handle to initiate operation.
The CitiZ has slightly more subdued appearance with more neutral colors designed to accent any kitchen without dominating with color. It is described in the marketing information as “retro modern” combining modern functionality incorporated into a sleek, cool looking retro design.
The CitiZ has a large lever operation to initiate the espresso pour.
Both machines are good looking, with the Inissia having a more fun, square style and the CitiZ being a little more sleek and urban-inspired cool.
The size of the water tank is always a feature I look to first when comparing machines
This is a big convenience factor and I like to see a little extra room to minimize the amount of refills I’m doing every week.
The water reservoir for the Inissia is 24 oz, so will provide enough water for up to nine espresso coffees. This means you’re refilling about as often as you’re emptying the capsule catch.
The water reservoir for the CitiZ is 34 oz, so it provides for about twelve to thirteen espressos before needing a top up.
Neither of these water reservoirs is especially large, so having the machines close to a water source is really helpful. I have the CitiZ and I have found the 34 ounce tank to be pretty manageable, especially if I’m just pushing the espresso button.
As a small benefit, a smaller reservoir means fresher water in the tank. Either way, Nespresso recommends descaling roughly every three months or after about 300 capsules, more often with hard water. See our guide to cleaning and maintaining your coffee machine.
The Inissia measures a petite 4.7" x 9" x 12.6" and weighs about 5.3 lbs, making it easy to move and ideal for a dorm room, small apartment or home office. Today, the Essenza Mini has taken over as Nespresso's smallest machine.
The CitiZ is not significantly larger, measuring a slim 5.1’’ x 10.9’’ x 14.6’’. The CitiZ weighs a slightly heftier 7.3 lbs, which isn’t a significant difference, though it is worth noting if you have space concerns. I love the CitiZ for the office or home.
The biggest difference between the Inissia and the CitiZ is the milk frother. This is the make or break factor for most users.
The CitiZ is sold as a CitiZ & Milk bundle with a matching Aeroccino frother. It's insanely convenient: fill it with milk, press a button and you have frothy milk for a latte.
The Aeroccino is great for making lattes, cappuccinos or milk for iced coffee.
The Inissia doesn’t come with the Aeroccino, but you can purchase one separately if you find that this is a feature you want to add on or try these tips on how to froth milk without a frother. If you aren’t a die hard milk-based espresso drink fan to start with, you may want to wait and test the waters with straight espresso and lungo shots first.
Both the Inissia and CitiZ are great quick fixes for espresso that anyone can use and enjoy, no previous experience or barista skills needed.
The beauty of the system is that it is so easy and the end result is high quality and really tasty.
When comparison shopping, keep in mind the Inissia was Nespresso's base model, designed to give you the basics at the lowest price. That role now belongs to the Essenza Mini.
The CitiZ is a couple of rungs higher on the Nespresso ladder, with a larger water tank, a sturdier retro design and the popular milk frother bundle, for a higher price.
Generally, the CitiZ is a better pick for someone who knows a little more about their espresso preferences and is willing to make a bigger investment.
