I have five portable espresso machines, the Nanopresso is undoubtedly my favourite and the one I’d recommend.


I’m a huge fan of manual espresso machines. I’d say 80% of all the coffee I drink is extracted from a portable coffee maker. My passion started with the Aeropress which isn’t actually an espresso machine, but it still makes a damn fine coffee. Up until getting my hands on the Nanopresso, I’ve been switching back and forth between the Handpresso and the Staresso.

My experience with these other devices has given me a strong understanding of the intricacies of dialling in a perfect coffee extraction. Armed with this knowledge, I’m confident I can get the best out of the Nanopresso and I hope you find this review and demonstration helpful.


The Nanopresso comes in a good quality retail box. Inside you’ll find a detailed user guide, a warranty card, and a couple of stickers.

The user manual is extremely well illustrated. It includes a detailed step-by-step guide, tips for getting the best results, a troubleshooting section along with details on the cleaning process.

It’s very simple to follow and printed in a total of nine languages.

The accessories that come with the Nanopresso Portable Espresso Maker

Unlike most portable coffee machines, the Nanopresso comes with a top quality hard carry case as standard.  The Handpresso has its own similar case, but it’s actually an extra $25.00 on top of the cost of the product.

If you intend to use the Nanopresso on your travels, this case will come in super handy. It’s lightweight and moulded perfectly to house the device without taking up hardly any additional space.

3The Design and Build Quality

I’m struggling to describe just how impressed I was handling the Nanopresso for the first time. I don’t want this to sound like a sales pitch, but trust me when I say it’s practically flawless in its design and build quality.

Its capsule shape is a delight to hold and the deep knurled top and bottom provide the perfect grip when tightening and loosening the components. With your thumb and forefinger comfortably resting against the raised edge of the pump it really could not be easier, even with wet hands.

Despite the Nanopresso’s body and components being made from plastic, it somehow feels very robust and solid. That being said, it still comes in at just 333 grams (11.7oz) on my scales.

Weight may not be a huge factor for most people, but if you’re into hiking as I am, every gram counts. In comparison, the Handresso’s weight comes in at almost 500 grams.

The Nanopresso Components

When you disassemble the Nanopresso for the first time, you’ll find seven individual components. Only four of these are essential to the device. Those being the Portafilter, coffee basket, the main body and the water tank. Additionally, there’s also a coffee scoop and cleaning brush, they both fit neatly into the water tank. The Nanopresso also cleverly comes with an Espresso cup that clips securely to the underside.

The individual components inside the Nanopresso Portable Espresso machine

Each item fits together with absolute precision. As hard as I try, I simply cannot find fault in any individual part. Components that require durability, such as the filter basket, are thick and robust.

I have absolutely no doubt that you could bash coffee pucks out of the basket all day long without damaging it.

The Nanopresso filter basket

There has clearly been a substantial amount of thought given to the Nanopresso’s design. The water tank requires less than a quarter of a turn to tighten and is impossible to cross thread. As for the portafilter, it screws on so cleanly, it almost causes ASMR tingles up the back of my neck, I kid you not!

Anyway, all of this design and build goodness is irrelevant if the extraction is not up to scratch, so let’s take a look, shall we?

4Using the Nanopresso

I’ll briefly explain the process here, as I’ve already demonstrated it on my Youtube video.

  1. Measure 8 grams of coffee and add it to the filter basket. If you’re using the scoop, it’s pretty much level with the top.
  2. Use the scoop to tamp the coffee into the basket and make sure it’s nice and tidy. The manual suggests a hard tamp, this will be dependant on how fine your grind is.
  3. (optional) Preheat all components using boiling water.
  4. Drop the basket inside the Nanopresso and tighten on the portafilter.
  5. Discard the water (assuming you didn’t skip the preheating phase) and add fresh water to the tank. Make sure it’s no higher than the maximum line (80ml). Now carefully tighten it to the base.
  6. Twist the pump anti-clockwise to release it from the chamber.
  7. Turn the Nanopresso upside down and begin pumping the piston once every second. Continue pumping until you’ve extracted your preferred quantity of espresso.

5My experience with the Nanopresso

I started with the exact same setting on my Hario Mill that I use for my other portable espresso machines and made my first Nanopresso coffee. In front of me was a delicious espresso. It was full of flavour and detail, with a good temperature and an impressive looking crema.

Over the last few days, I’ve been experimenting with the grind and I’ve taken it from one extreme to the other. Too fine and the Nanopresso will slow drip during the extraction,  too coarse and the flow will be excessive.

There is a fairly large window for adjustment, so you should have no trouble finding your own sweet spot.

Extracting an espresso with the Nanopresso

In a perfect scenario, you’ll have a freshly roasted bag of beans at hand along with a suitable grinder. This is not always the case. I have tried three different pre-ground coffees and they all have worked well with the Nanoresso.

6The Versatility of the Nanopresso

For those that need an even easier preparation method, Wacaco have released an NS Adapter. This will allow you to drop a Nespresso capsule inside the portafilter instead of using the filter basket. There’s also a Barista kit to give you a double shot of 16 grams and a larger water capacity of 120ml.

My Nanopresso Barista Kit YouTube Review


I have absolutely no doubt that the Nanopresso will be my portable espresso machine of choice. It’s lighter, smaller, yet more powerful than my others devices. The piston is as quiet as a mouse and a pleasure to use. The build quality is precise and all elements of the design seem spot on. The integrated espresso cup and the hard carry case make it ideal for travel or for using outdoors. Most importantly, it makes an amazing espresso coffee.

  1. Hey there, anyone getting leaks around where the adaptor ring seams against the nanopresso body and the nanopresso head? I get small droplets of coffee seeping out when I make a double shot coffee. Any advice as I currently just get coffee all over my hands whenever I make one..

    • Hi Christopher, I sometimes get the same issue, It didnt happen in the single shot setup, even when the portafilter was loosly tightened. With the double shot adapter, it’s important to tighten it up more than you would normally. Before I begin my extraction, I just give it a little extra tighten, this usually prevents any dripping. It also helps if you don’t pump it too fast, I aim for a steady flow that’s slightly thinner than the thickness of a match stick. Hope that helps.

  2. Are any of you guys having difficulty with making a second coffee on the nanopresso? I use the barista kit to make two double espressos for me and the missus. The first always works perfectly, but the second (even though the grind and tamp pressure and technique are the same between the two filter baskets) simply doesn’t pump out easily. Funny thing is, if I wait a while, then the ‘first’ coffee is always perfect, it’s only the ‘second’. So i’m assuming the valves have expanded due to the heat or something? Anyone else had this experience? I sent them an email about it, but no response yet.

    • Hi Chris,

      I’ve had a few occasions when my second espresso seemed to extract differently from the first. I assumed it was from having some residue in the portafilter from the previous basket. There is a release valve inside the system that kicks in when the pressure goes over 18 Bar, maybe this valve is opening on the second pour for some reason. I haven’t experienced this problem recently, even though I often make two consecutive quite often, this may be because I do a little flush of the pump under the tap between extractions. I do this because I had a small issue due to limescale getting into the pump. I simply take the main body and place it under a running tap, I then pump it about a dozen times to push clean water through the valves. Since I started doing that, I have had an awkward second extraction, so maybe give that a try. Have a great day.

  3. In the Barista Kit it says to remove the black silicon part inside the spring for best results. It doesn’t say why this would give the best results. Any idea what this is and why it’s best to remove it?

    • Hi Micheal, when you remove the black silicone part it makes the portafilter nozzle unpressurized. I have had it this way for the last two weeks now. In all honesty there is no difference in the taste, unless you’ve made your grind slightly finer. I’ve found that I can take my Hario Mill one click more on the grind. This will help produce a slighly less bitter espresso. If you keep the grind the same, the only difference would be the amount of air in the crema. With the part in, the crema will be bigger due to more air bubbles inside it. Without the part, the crema will be smoother in appearance and not quite as big. Hope that helps, have a great day.

      • Ah ok I’ve got you. I tried it this morning in un-pressurized mode with a finer grind but I’m pretty sure I tamped it way too hard as it required a lot of force to come out, and did so in drips. got a couple more coffees left for the day so I’ll get it fine tuned. Thanks for the help Simon!

  4. Did you check the main body of nonopresso in the water chamber side, there are 4 silicon stoppers on top of 4 screws inside the main body, you need to maker sure they are all in places

  5. Hi Simon – I’d decided on the Nanopresso based on your reviews, especially as I was also interested in getting the Barista Kit, which I did a month ago for both. First-rate espresso with excellent crema! Have used it, on average, about 3-4 times a week for a month (I like espresso, but not everyday) and have been meticulous about cleaning it of grounds between extractions and regular cleaning each week.

    Has your own Nanopresso stopped creating any pressure at all yet? After a month, mine has stopped creating pressure. Deeply disappointed. Obviously, I’m not attributing the fault with you at all as I feel I can trust your thoughts/reviews on a failing Nanopresso. If yours is still pumping well, then that’s great. If not, then I was hoping you’d comment on this or create a video if it should ever happen to yours. Hope not, though. Happy holidays!

    • Hi John,

      The timing of this question is perfect and I might be able to help you out here regarding your issue.

      I’ve been using the Nanopresso for over 5 months now, I’d say I’ve made close to 500 espressos in that time and never experienced any issue with loss of pressure. That was until last week (over the Christmas period) I was making family members drinks and during that time I noticed that the initial pumps required to begin the extraction were increasing.

      Eventually, it got to a point where I could pump and pump and it just would no longer extract. I toyed with the unit and discovered that if I loosened the portafilter after I’d pumped for a while, then tightened it back up, it would begin building pressure and extracting as it always did. This additional step was not ideal but did allow me to continue using the Nanopresso as I had before.

      Just yesterday I contacted the guys at Wacaco to ask them if they could suggest a reason for this and together we went through a fault diagnosis. During that time I was asked to take just the main body and place it under the tap and start pumping. I was then asked to look at a small orange cross-shaped pin and see if there was movement. There was, (about 1mm of travel) The water was also making its way through the device. While I was pumping cold water directly through the unit, I could see a noticeable improvement in its efficiency.

      When I put the portafilter, basket and tank back on and pumped it as a complete unit, it worked flawlessly once again without any need to release the pressure from the portafilter.

      I am pretty sure that what had happened was no more than a partial block in one of the pump valves most likely caused by small amounts of limescale from my kettle. The process of pumping water directly from the tap has flushed whatever was there through and it’s now back to 100%.

      So, my advice is to take a look at the small orange cross on the underside (while it’s under the tap) and make sure that it’s moving during pumping, if it is, just keep pumping the water through and hopefully your unit will flush whatever is in there though.

      If that doesn’t work, I highly recommend you contact Wacaco, they are a great bunch of guys and I’m sure if there is a mechanical fault, they will definitely replace the unit.

      Hope that helps.


      ps. Please let me know if this worked for you.

      • Many thanks, Simon. For whatever reason, checking that the orange cross-thingy got “pushed out” by about 1 mm while pumping water (without the portafilter or tank) did the trick. If a bit of limescale is the issue, I wonder if a periodic deep cleaning using a non-toxic de-scaler is needed. And here’s to perfect timing on your response… we can enjoy espressos on New Year’s Eve. To you and yours!

        • I’m so pleased it worked for you! I’ve been pumping fresh water directly from the tap when I clean out the unit, I think that extra process might be enough on its own to keep the system healthy. If not, I’ll look into a non-toxic descaler. Have a great new year and thank you for taking the time to respond.

  6. Great review of the Nanopresso. Which portable espresso machine would you recommend for performance and portability?

    • Definitely the Nanopresso, it’s the smallest and the lightest if all the espresso machines I’ve tested. If you don’t mind not having a Crema and want an even lighter option, take a look at the Aeropress. It’s not an espresso machine but it does make insanely good coffee. If I’m doing a big hike and want the absolute minimum weight, I’ll take the Aeropress.

  7. Hi Simon,

    Thanks for your review! How would you say the nanopresso compares to handpresso and staresso in terms of the results?

    • Hi Michal,

      So sorry for the late reply, I can get a great quality coffee from both the Staresso and the Handpresso. You don’t have much control over the Handpresso regarding the pressure, you press the button and it just releases the pressure on its own. So the consistency is there, however, I’ve never been able to improve the crema, also the water capacity is also on the small side.

      You have more control over the results with the Staresso, once you’ve used it for a while, you’ll learn the perfect amount of pressure and speed to get a great espresso out, it’s like muscle memory. The same goes for the Nanopresso, which in my opinion is a far better product, the pressure and the pump mechanism is way better than the staresso. I know it’s a little more expensive than the Staresso, but I think it’s well worth it.

  8. Thank you for the review, I subbed to your YouTube channel, the video was great. Looking forward to seeing a demo of the Barista kit!

    • Thanks Sara, I cannot wait for the Nanopresso Barista Kit, I check the Wacaco site almost on a daily basis in hope that it’s been released. I might email the company for an update on the ETA – Thanks for the sub by the way 🙂

      • Hi, Thanks to Simon for all these reviews of portable coffee makers. Desperately trying to choose a replacement for our my pressi twist* and you seem to be the only person systematically trying them all – so thanks!
        I had an email from wacaco yesterday that the accessories should be available from their website in the next week or so, so fingers crossed to be able to order them for delivery before Xmas!

        * The my pressi twist makes amazing coffee, but you can’t fly with the gas canisters so we can’t take it on holiday, and ours is starting to leak gas pressure after many years of good service and I don’t have the patience to disassemble it and replace all the o-rings. But it does match our Gaggia kitchen machine for quality of espresso and makes a double shot fine. If you can find one its worth trying!
