What's with the constant reference to 18bar pressure in the advertising material? It's weird.
After a fairly underwhelming experience with the newly acquired Aeropress on an overseas trip recently, I came across the Nanopresso, successor to the Minipresso which was discussed briefly earlier on this forum. For $59 USD I figured it worth a shot (sorry about the pun!) and have preordered one.
Has anyone else ordered a Nanopresso? Or by some chance had their hands on a pre production sample? Backup for the original Minipresso appears to have been good and total investment is not massive so I'm giving it a go. Perhaps one day I'll spring for a Rossa HC but for now the Nanopresso looks like the next step.
What's with the constant reference to 18bar pressure in the advertising material? It's weird.
The photo where it talks about cleaning it showing the spring reminds me of the insides of the pressurised portafilter of my in laws via venezia. That and saying how pre-ground coffee works well made me wonder if the 18 bar is to do with that?

Hmm just did a search and it looks like the original Minipresso effectively has a pressurised portafilter...
OK I've arranged for a refund. The mention of the pressurised portafilter was enough.
I think I can see a Rossa HC or similar in my future though...
I've used a Minipresso and I was really impressed. It's not quite true espresso, but it's probably the closest you'll get with something portable like this. The two main problems with it are that it's difficult to pre-heat sufficiently and it's a little difficult to squeeze at times. Anyone that tried to eke a bit more out of it with a finer grind or slightly higher dose ran the risk of unseating the valve as well. It was an easy enough fix if this happened and Wacaco were quite onto it in dealing with this issue, but still not ideal. It sounds like the improvements they've made when developing the Nanopresso will make for a great little unit. It's still only officially rated as an 8g filter basket, but I reckon you'll get 9-10g in there most of the time easy enough. And if the pump and group unit is a bit more robust to allow for a higher pressure extraction then it could be a good thing. I'd be keen to give the Nanopresso a go when it comes into full production. Pressurised portafilter? Well, sort of. There's a pressure activated valve in there, but I don't really see how that's a bad thing.
Hi everyone, I'm Hugo the designer of the Minipresso and the Nanopresso. I'm new here and I register specially to reply about your concerns. I would like to confirm that Minipresso and Nanopresso come in standard with pressurized portafilter. You need to understand that most users are not expert and wish to get a nice and good espresso every time, whatever the coffee ground they are using. But this function can easily be cancelled in both of our machines by removing the small black silicon part link to the spring. However users will then have to work harder on the grinding.
@MattyRay, you should have post this question about the pressurized portafilter at the bottom of the blog post in the comment section. I will have been more than happy to answer you and avoid any disappointment.
Thanks for the comments Hugo. Can you confirm if removing the pressurising pin from the minipresso will not void the warranty? I've seen several mentions of pump seals blowing from too much pressure, but these comments have all been fairly old. Have the newer minipresso units been improved? I really don't want to test the limits of my unit it with too many choker shots!
As an endorsement, I've just finished a 3 week 4WD trip through the remote Kimberly area. The minipresso was paired with a Rhiniwares compact grinder and used every morning for 2 milk drinks. My wife and I couldn't have done without it. We had a mocca pot as backup and never used it.
It would be nice to be able to buy individual spare baskets. I would rather keep the small reservoir and use boiling water for each shot instead of the large reservoir getting cooler as you go, plus fresh ground beans on the spot negate the desire for preloading the 3 spare baskets in the reservoir kit that will just go stale.

i must admit I was a little disappointed to hear that the Nanopresso had a pressurised portafilter, but I had no idea it could be bypassed. Nice to hear it can be used unpressurised though, most of us here don't mind working on the grind as it's an integral part of what we normally do.
I haven't yet purchased another portable device, so will perhaps take this one out of the "no" basket and reconsider.
Thanks for the update.
On the Nanopresso, everything has been developed to handle the high pressure. The portafilter can be very easily open for cleaning or to cancel the pressurizing device without causing any problem for the warranty. I have already run few test without it on single and double espresso. For sure the result is incomparable. The crema is very smooth. I will try to talk about this in the bog post and show an example.
Thanks for the feedback. Looks like I might upgrade!
Hi Hugo. Can you please tell me if the kit+ with the 3 minipresso filter baskets will fit the nanopresso? This would be great for traveling as would the larger water tank. Also, when will the Barista kit and NS adaptor be available in Australia?
I'm keen to get one to try. Will probably also get the Barrista kit to produce bigger shots.
I'm very keen to get one of these. Definitely getting the nespresso pod adapter. What I'd like to know is, with the barista extension, will the nespresso pods be over extracted?
Hey guys where can I pick up the nanopresso, the ns capsule adaptor and the barista kit? I did up the cost from the wacaco website. $170aud or so. Seems a bit steep for what it is.
Anyone found it cheaper elsewhere?
Site sponsor Coffee Parts has them. You can throw yourself to the wolves on evil bay where you can be warned about fakes, especially by one vendor whose price is so "to good to be true" that it can be reasonably deduced that they are in fact selling fakes!
I ordered mine from Alternative Brewing. $90 I think + post. They don't have the Barrista kit available at the moment
Hope I am not breaking any site rules to let people know I have just ordered a Barista kit directly from Wacaco Hong Kong for US 29.90 with free postage
Im quite shocked at the price of the adaptor kits. Especially for the nespresso pod adaptors!
Anyone had pump issues with theirs? Mine wont build pressure anymore, and from the support line there is a small seal that often gets unseated, allowing blowback from the pump into the water reservoir. Quite disappointing given it was 4 days old when this happened.
Very very glad i slung the Aeropress in as well on a whim. (and i was in New England where you can get decent cortados)
After deciding I couldn't risk the Bellman not working on my cooktop I decided to go with one of these and go back to using a french press to froth milk when I want a milky drink.
This is after about 4-5 days playing with various settings.
Both shots tasted pretty good. The cold brew was not quite as nice as the 'nitro shot' cold brews that are sold in my area. But not too bad.
The beans were roasted about a week ago.
I took out the spring from inside the portafilter to unpressurise it.
Espresso Shot with Sunbeam EM0480 grinder. Setting 11. Tamped very hard. Unpressurised portafilter
It started coming out in a solid stream at the 7th pump
Cold Brew Shot with Sunbeam EM0480 grinder. Setting 11. Not tamped as hard. Unpressurised portafilter
It started coming out in a solid stream at the 5th pump
re the "espresso" shot, How many grams in HD? and what volume/grams out? thanks.
I am afraid I am not yet in the habit of measuring as of yet. I tamped to within 2 mm or so from the top.
My understanding too. 10g of ground in equates to about 20g out at the standard 2:1 ratio?. I don't know what size the shot glasses pictured are but I am assuming they are not 450ml behemoths and are more likely 60-80ml? that espresso pull looks like a lot of extraction from a humble 10g. Also not sure about the cold brew:
HappyDaisy did you force cold water through ground beans as per a normal espresso pull or did you use some sort of longer time based drip arrangement using the nanopress?
I wouldnt be using the nanopress for cold brew thattaway HappyD - I use the slow steep method of immersing 200gish of fresh coarse ground in 1l of cold water in the fridge for 12 hours - yummo. Forcing cold water thru fresh ground in a portafilter will not achieve anywhere near the same taste results - but if that is what you like - heh - although I can see an option for using the nanopress in a cold drip set up - again cold dripping over a reasonable time period.
Yep, I've done cold brew in a French press like that previously. Left it overnight in the fridge. Was curious to see how the nanopresso would handle it. My wife still prefers her 'Nitro' cold brew from the specialty shops around Canberra so I haven't tried to improve my process lately.
I'm wanting to 'depressurise' the nanopresso as described by Hugo, but am a little unclear on where in the apparatus the pin I need to remove is.
Does anyone have pictures, or a guide for doing so?
I've left the spring out. It doesn't seem to do much without the silicone pressurizing widget. I suspect it will collect oil though if left in.
Yes take the spring out to depressurise.
So I just used this for the first time. I ground up 8 grams of coffee but it didn’t all fit in the portafilter. Silly i forgot to measure how much I actually put in, i will have to do next time. I pre heated and then pulled an unpressurised shot. I used the same grind setting and beans that I’m currently using on my E61 espresso machine.
I started pumping - coffee started coming out at around pump 5. It took me about 30 seconds to extract 16 grams of coffee in the cup.
I had it as an espresso. Taste was like a weaker espresso. It wasn’t as thick as the coffee out of my espresso machine. However that may be due to the smaller basket size as I suspect pushing the water through double the amount of coffee would make the flavour more intense.
nor bad for a first go and I will play around more next weekend
i has another go this morning. This time I managed to get all 8 grams of coffee in by filling the little cup a couple times. I also paused 1 sec between pumps. The result was probably too much pressure as extraction time for 16g was around 45sec.
I did pre heat the unit and I noticed that the first bit to come out of the unit was some left over water so I might extract th first pump into a cup next time to avoid it watering down the coffee.
Result was was a big improvement on last night. I’d like to try it again with the grind right and no early water in the cup. Pausing between pumps really helps as a pre infusion. A side by side comparison to my espresso machine showed that it’s not as rich or complex, but it’s not bad. Again that may b due to 8g basket as opposed to 18g basket. Im also drinking it as espresso which is going to show it up.
The 16g basket that comes with the "Barista Kit" is a lot more forgiving than the stock 8g - and I am getting pretty darn close to a "true" espresso shot with the 16g - not as tasty but that is probably more related to my newbie nanopress technique (still in development stage or grind rather than anything to do with the device. Hoping that a bit of slack time over the break will give me a chance to achieve some more nanopressive shots. Warming, I fill the res with hot water from the hot water tap of my espresso machine and let it sit whilst I prep. I then purge the nanopress, refill with hot water and purge again (now it is bluddy hot). First drop of extraction I waste.
Yes 2 hot purges, the first is a preheat really, the second hot purge, just prior to pulling, gets it snuggly hot. Not sure if the second purge is completely necessary but after doing some temp readings, the cup difference between one and two hot purges is quite substantial.
I did read online about someone using the nanopresso to do new espresso drinks - ie filling it with whisky and brewing the shot with it. Could be fun
This happened to me a few days ago. Have not been able to get anything out of it since... Did the support line tell you how to resolve it? Or was it a case of return to sender...
I found a youtube video with this comment on it, didn't help me though. Even without any beans in it and the spring back in place nothing comes through.
Hi there! Have you got your solution already? Even if you got a new replacement, it will appear again. And eventually, this might not a problem at all. The solution is simple enough. At the side of the pump where we put water tank, you will see 4 rubbers to cover up the screw, then pay attention to the “+” sign orange colour rubber. I believe it was not pushed down. Push it down with your finger or screw driver or toothpick to close the valve. Trust me, you ll be able to pump it again. The biggest problem of this product is it has possibility to have water leaking at the piston and the side between the body of pump to portafilter. No wonder, high pressure portable device. A bit troublesome.
It took more like 20 minutes of pumping (At the end I was at a slight angle with the pump facing upwards).
But after that there was a pop, hiss and suddenly I was getting water.
Half way through (10 minutes in) I opened the water chamber and pushed the orange cross in, not sure if it did anything but it did hiss at me.
Tomorrow morning's coffee fix will tell me if this actually worked or not though!
Edit... Didn't work. Didn't feel like pumping for another 20 minutes on the hope of getting lucky
2nd Edit: Tried again this afternoon. It worked perfectly this time around. I didn't bother tamping very hard and had the pin in so the coffee did not taste nearly as nice as the ones I made earlier in the week. Maybe it is fixed, maybe not. I'll keep trying.
