Just downloaded footage from my secret webcam in the kitchen of @"DavecUK"#1 only to discover that he's been holding out on us! Cmon Dave, spill the beans (not the coffee ones) on this geourgeous looking leva. [URL=https://i.imgur.com/Y7e0uuz.jpg][IMG]https://i.imgur.com/Y7e0uuz.jpg[/IMG][/URL]

For this machine it's one of the first made, and I am doing an Engineering review on it for Antonio (the creator) as a favour, so I can't really comment at this stage. But I can post photos….and say that the Paddle levers on this are very basic beta ones….so that area is still in the design melting pot.

needs to be 50mm shorter for a uk work top haha i believe this is a commercial focsed machine?

I love the look of these sorts of lever machines, but they really need to at least try to make them a bit more compact in design. They're either lacking in that area of expertise or they don't care… A more compact design would look like a much better centre piece in a kitchen (and take less space in a commercial setting), rather than protruding till the near edge. The size distracts from the elegance of it.

Certainly a looker. I'm sure we will all look forward to your thoughts when you are able to comment.

@"Cuprajake"#p10000 no it's for the home market

@"Cuprajake"#p10000 from the nurri website https://www.nurri.coffee/portfolio-item/nurri-leva-sa-machine/ L-TYPE LEVA S.A. is a professional machine. Yes. But it is designed for those who want to enjoy quality espresso at home, making it with the same passion and competence of a professional bartender.

@"tompoland"#p10004 I like how they stuck Patent Pending on everything 🤣 a bit unprofessional.

@"Sham"#p10001 I agree when it comes to similar sized Levers that require external plumbing or flojet type arrangement. But the Nurri is dual boiler and plumbing is optional. Still, I agree that it's a lot for a normal kitchen. I like the footprint on the Decent for example.

Powder coated version. Wow. [URL=https://i.imgur.com/7uFzqtw.jpg][IMG]https://i.imgur.com/7uFzqtw.jpg[/IMG][/URL]

@"tompoland"#p10007 In that case they should have either decreased tank sizes and utilised quicker water heating technology (I'm sure there's loads of options from other industry's) or started with a more wide design but I guess that would've cost too much R&D time. One way to think of it is that they won't lose customers if its small, but they will lose customers if its too big. It does look pretty nice though.

Suppose it depends

There’s the declining pressure profile and then there’s the temp declining too, I know this can go as much as 4-5 degrees swing.

DavecUK

mathof2 I thought one of the advantages of a traditional spring lever machine was meant to be that the brew water temperature (as well as the piston pressure) decline

Where and when, did declining brew water temperature come from?

mathof2

DavecUK It comes from the fact that on large spring leavers, the big group acts as a heat sink. As a matter of taste preference, I’ve often seen it praised.

On another forum, John Buckman of Decent espresso machines, recently said: ’The “Adaptive” profile that is my daily … does this temperature drop as part of the program. It’s currently the “most popular profile” on https://visualizer.coffee/ I have it set to drop 5C on my profile, but you can set it to be whatever you like.'

Asked what he thinks is the advantage of a temperature declining profile, he replied: ’I’d say the taste is “smoother, less harshness”.'

DavecUK

mathof2 Sounds like a recentish thing then

mathof2

Obviously, the phenomenon is not recent, as it happens automatically in lever machines that don’t have something like cartridge heaters to keep the group temperature in balance with the brew water in the cylinder.

As to when it was positively credited with helping to give lever shots their characteristic flavour, I feel as though I read it first many years ago (but I couldn’t say where).

I know where Dave is coming from because big levers have been praised for their temp stability….

I like it to this new Weber portafilter that seems to channel. App visual channeling on the bottom of baskets is a good thing now

tompoland hello tompoland, have you or any of the other people on this thread who ordered the nurri l-type received their units yet? As a fan of LSM type spring levers (of which there are never enough of), I am eager to hear how your experiences have been like with this very interesting machine.

tompoland

chlorox hi there I have not received the Nurra Leva SA yet. It was scheduled to ship from Italy to Australia at the end of July but that has been pushed back to the end of September now due a part not being delivered ot the Nurri factory in time.

There are others who have received their units and one on this forum in particular offered a lot of comments and of course our illustrious Espresso Leader Extraordinairre @DavecUK has a prototype on his bench.

Early reports are undoubtedly colored via the honeymoon effect but nevertheless positive comments abound. I’ll be sure and post a pic and a comment or two here once she is on my espresso bench. I’m thinking Christmas present from santa?

DavecUK

tompoland has a prototype on his bench.

I had an early production model, but I returned that months ago, as soon as I finished the engineering review.

I don’t know how much of what I recommended will be changed, or implemented.

The same with the GTO, I returned it as soon as the engineering review was completed.

chlorox

tompoland thanks for the reply…I hope you will receive it in September and am looking forward to your report and the report of others on it!

I firmly believe that the more temperature and pressure controllable lever machines there are being sold out there, the better the scene for lever lovers - especially when they use the LSM grouphead. I say this as a long time user of an Izzo Pompei and I would not want to use a modern lever with any other grouphead.

The better the nurri is, the more that will spur the Vesuvius Evo to greater heights and the more I hope this will cause espresso enthusiasts to consider the lever rather than boring pump machines, even those as powerful as synessos and gs3, which will in turn cause more machine manufacturers to introduce more advanced lever machines like the nurri and the vesuvius evo - all to our ultimate benefit!

Cuprajake

That’s a shame on the delay, it’s happening alot atm,

tompoland

Cuprajake

Cuprajake Sure is. I had an eleven month wait for the Malwani Livi. At least with the Nurri, it was a deposit only required of around 15% with the balance due once it’s on the ship. Many others direct-to-consumer manufacturers require full payment upfront with wait times of many months.

Knluk

DavecUK hi Dave, did you share your review somewhere? Can’t seem to be able to find it. Thanks.

tompoland

Got it. Thanks for the update. In that case I hope to be able to report in and confirm that Antoni adopted your recommendations.

Cuprajake

Yeah I know a guy with a p64 that got pushed back and another with a Weber eg1 who paid in full and got pushed back like 5 months

chlorox

Knluk what i read was that Dave was asked by Nurri to give his engineering feedback for the purposes of product improvement and so it is confidential.

Knluk

chlorox thanks. Sorry for the misunderstanding. Thanks Dave for improving the machine for the potential owners!

DavecUK

Knluk Assuming any of my recommendations are acted upon.

Paolo5

Hi Dave….do you know if the Nurri uses a vibratory or rotary pump for pre-infusion?

DavecUK

Paolo5 Hi Dave….do you know if the Nurri uses a vibratory or rotary pump for pre-infusion?

It uses a rotary pump, in the early machine I tested. You adjust the pump balanced bypass for the preinfusion pressure you want, via a hole in the case. Mine was a very early model, so I could give Antonio some engineering feedback…not for a public review.

It might be that in current models it’s different, but I am sure they wouldn’t use a vibration pump?
