Viernes The Nurri also responds well to keep stable the desired temperature. At least in my experience
If you mean stable throughout the shot (as opposed to between shots), 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) declined throughout the shot.
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.

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

Probably on CFUK back in 2012/13
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.
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?
That’s a shame on the delay, it’s happening alot atm,

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

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!
