The Nespresso De’Longhi Lattissima One is the smallest, simplest milk-drinking Nespresso Original machine. One button for espresso, one for lungo, one for cappuccino or latte macchiato with automatic milk frothing and a single-serve milk jug. If you want one milk drink a day without learning to steam milk, this is the machine De’Longhi built for you. If you make back-to-back lattes for two people, it will annoy you.
It’s an Original Line Nespresso, so it uses the small Original capsules, not Vertuo. That matters for cost, capsule variety, and taste. Original capsules are cheaper, available from Nespresso and dozens of third-party roasters, and lend themselves to stronger, shorter espresso. Vertuo gives you larger coffees but locks you into Nespresso’s capsules.
What the Lattissima One actually is
De’Longhi makes several Lattissima models for Nespresso. The Lattissima One (EN500) is the entry point. It has a 19-bar pump, a 1-liter water tank, a used capsule container for about 8-10 capsules, and a 120ml milk jug that clicks onto the front. The jug is portioned for one drink – you pour milk to the line, the machine siphons it all, froths it, and flushes itself afterward.
There are no milk settings to tweak. No foam density dial, no temperature control. You get what the machine gives you: hot, fairly airy foam, automatically deposited before the espresso. Press the milk button once for a smaller cappuccino-style drink, hold it longer for a taller latte macchiato. That’s the extent of customization.
Dimensions are compact at roughly 15.5 x 25.5 x 32 cm. It fits under low cabinets where the larger Gran Lattissima does not. Finish is mostly matte plastic. It looks clean but does not feel premium like the metal CitiZ or Pixie.
How it brews day to day

Heat-up is fast, about 25-30 seconds from cold. Insert capsule, fill milk jug if you want milk, press a button. The machine reads no barcode – you control volume. Factory defaults are ~40ml for espresso and ~110ml for lungo, but you can reprogram them by holding the button.
The workflow for a milk drink is: pour milk to the max line, attach jug, press milk button. The machine steams and froths the milk directly into the cup, then brews espresso through it. When it finishes, it prompts you to run a quick rinse – turn the jug dial to the clean position and it pushes steam through the milk spout into the jug. Takes about 10 seconds.
For black coffee, you just ignore the jug. It works like any other Original machine. Noise is typical Nespresso: loud vibration pump for 15-20 seconds.
The single-serve milk jug: clever and limiting
The One’s signature is that detachable 120ml jug. De’Longhi designed it to solve the biggest complaint about earlier Lattissimas: leftover milk sitting in a carafe in the fridge.
Pros: you only heat what you use, so milk doesn’t spoil in the machine. The jug is small enough to store in the door of a fridge, has a lid, and is dishwasher safe. Cleaning is simpler than a full carafe with a tube.
Cons: you can only make one milk drink at a time. For two lattes, you have to fill, brew, rinse, refill, brew again. The process takes 3-4 minutes for two drinks. The jug also dictates the milk volume – you can’t make a 6oz flat white and a 12oz latte back-to-back without measuring. And the foam is fixed. It’s a dry, cappuccino-like foam, not the wet microfoam you need for latte art. If you like flat whites or cortados, you will not get them here.
The auto-rinse helps but does not replace washing. Milk still coats the inside of the jug lid and the siphon tube. If you skip hand washing for a few days, it will smell and eventually clog.
Drink quality and capsule reality
As an Original machine, extraction is identical to a $150 Essenza Mini. Same pump, same thermoblock, same 19-bar brewing. The Lattissima One does not make better espresso. You are paying for the automatic frother.
Espresso is what Nespresso Original does best: consistent, crema-heavy shots with little bitterness if you use lighter capsules, more roast-forward with Intenso/Ristretto capsules. Temperature is hot enough for milk drinks – around 67-71°C in the cup for espresso, lower for milk drinks after the cold milk is added.
Milk drinks come out hot but not scalding, around 60-65°C. The foam is thick and spoonable on top, with thinner hot milk underneath. It holds for a few minutes then separates, which is normal for auto-frothers that whip air in mechanically. Whole milk froths best. Oat and soy work but produce taller, stiffer foam and can sputter. Skim milk makes almost meringue-like foam that some people dislike.
Capsule cost is the long-term factor. Expect $0.70 to $0.85 per Nespresso Original capsule, less for compatible capsules. One milk drink a day is roughly $25 a month in capsules alone.
Lattissima One vs. the other small Nespressos
Where it sits in the lineup matters because the cheaper option is often the smarter buy.
| Model | Milk System | Water Tank | Best For | Trade-off |
|---|---|---|---|---|
| Lattissima One | Single-serve 120ml auto jug | 1.0 L | One milk drink per day, tight space | One at a time, no foam control, plastic build |
| Gran Lattissima | 500ml carafe, 9 recipes, foam dial | 1.3 L | Households making 2-4 milk drinks | Larger footprint, milk left in carafe, ~$100 more |
| Essenza Mini + Aeroccino | Separate electric frother | 0.6 L | Cheapest way to get milk drinks, travel/small kitchen | Two-step process, frother to clean separately |
| CitiZ + Aeroccino | Separate electric frother | 1.0 L | Better build, same manual frothing | Takes counter space for two devices |
If you drink mostly black espresso or Americano, skip Lattissima entirely. An Nespresso Essenza Mini does the same brewing for less money, and you can add a standalone frother later if needed. If you make milk drinks for guests or a partner every morning, the Gran Lattissima’s larger carafe and second jug for rinsing saves time, even though it wastes more milk if you only make one drink.
Reliability and failure modes
The Lattissima One is generally reliable for 3-5 years of daily use, but it has predictable weak points.
1. Milk jug clogging: The siphon tube and the frothing nozzle are narrow. Dried milk blocks them. Symptom is weak or no froth, or milk sputtering. Fix is soaking the lid assembly in hot water and using a needle to clear the nozzle. Descaling does not clear milk protein.
2. Milk temperature drop: Over time the thermoblock scales, especially with hard water. Milk comes out lukewarm. Regular descaling with Nespresso descaling solution every 3 months (or when the orange light blinks) prevents this. Using filtered water helps.
3. Capsule piercing and leaking: If you reuse or use poorly compatible third-party capsules, coffee can leak around the capsule and into the drip tray. Stick to Nespresso or reputable compatibles with a proper rim seal.
4. Pump loudness increase: A louder, harsher pump often means air in the line after the tank ran dry. Prime it by running a lungo cycle without a capsule.
De’Longhi’s warranty is typically 2 years. The milk jug assembly is the most common replacement part and costs around $25-35 if you lose or crack it. You can buy a spare to keep in the fridge and rotate.
Who should buy it and who shouldn’t
Buy the Lattissima One if: you live alone or are the only milk-drink person, you want a one-button cappuccino before work with minimal cleanup, counter space is tight, and you are okay with Nespresso capsule cost.
Think twice if: you routinely make two milk drinks in a row, you want to control milk texture or make flat whites, you prefer large 12-16oz lattes (the jug is too small), or you want to use your own beans. For those cases, a small semi-automatic like a Breville Bambino or a separate milk frother for Nespresso paired with a cheaper Original machine gives you more control, though with more learning and cleaning.
Also consider that the Lattissima One rarely goes on deep discount. If you find a bundle where an Nespresso Original capsules variety pack is included, that is usually a better value than waiting for a price drop on the machine alone.
If the One isn’t quite right
For the same one-drink convenience but lower price: Essenza Mini plus a handheld NanoFoamer or Aeroccino. More steps, but cheaper and the frother can make cold foam too, which the Lattissima One cannot.
For more automation: Gran Lattissima or Lattissima Pro. You get a full carafe, one-touch recipes for latte, cappuccino, and flat white, and you can pour multiple drinks without refilling milk. You pay in counter space and leftover milk management.
For non-capsule freshness: If you are considering leaving pods behind, a compact bean-to-cup machine or a manual espresso maker will taste better with fresh beans, but requires grinding, tamping, and daily cleaning that the Lattissima completely avoids. Be honest about whether you will do that at 6:30 a.m.
FAQ
Does the Lattissima One make regular coffee or just espresso?
It makes espresso (40ml) and lungo (110ml) from Original capsules. It does not make Vertuo-style 230ml coffee or drip coffee. For a larger drink, brew a lungo and add hot water for an Americano.
Can I use oat, almond, or soy milk?
Yes, but results vary. Barista-edition oat milk froths closest to dairy. Almond milk often froths weakly and separates faster. Soy can foam excessively and may sputter. Whole dairy milk gives the most consistent foam and is what Nespresso calibrates for.
Do I need to descaling and how often?
Yes. Descale when the machine signals (both coffee buttons blink orange) or about every 3 months with moderate use and average water hardness. Use Nespresso descaling liquid, not vinegar, and run the full descaling cycle in the manual. Descaling does not clean the milk jug – wash that separately.
Is the Lattissima One better than the Essenza Mini?
Not for coffee quality – they brew identical espresso. The Lattissima One is better if you want automatic one-touch milk drinks without a separate frother. The Essenza Mini is better if you drink black coffee, want the smallest footprint, or want to save money. The cheaper option is fine if you don’t need daily auto-frothed milk.
