Nurri Leva S.A.

tompoland Thank you very much! So far I most been using a pump machine but I have decided I will buy a lever machine very soon, just so difficult to choose one.

Tjyven Ah, we have all been there! Make a list of the features you want. For example if you think that it is important to be able to steam milk, but not all the time, then look for a dual boiler. If you think it is important to have PID control of the dual boilers then look for that. If you want a machine that heats up in 15 minutes using heat cartridges, look for that. The ACS Vesuvius Evo Leva ticks all those boxes

dfk41 The ACS Vesuvius Evo Leva and Nurri both look really good to me except I probably want something cheaper. I do like machines that are rather simple but still can manage temperatures rather well. I drink about 95% espresso so steaming is not a must. The Strietman looks really good I think and lately I been looking a lot at the “chinese Strietman” if you heard about that.

tompoland I totally agree with you, having right temperature is essential. Also been using La Pavoni and even though I really like those machines getting right temperature is not easy.. However, I do think this “Chinese Strietman” is better than you probably think, even though there arent much information about it I know it is not some mass produced copy, it is actually one person who builds these machines by hand and it has a PID and I do think it is very temperature stable. As I said it is difficult to get information but Brian Quan has made a video:

I did not mean to hijack this Nurri thread and maybe this should be moved to a new thread.

Tjyven Is that really a surprise though!

dfk41 I guess not!

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 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”.'

mathof2 Sounds like a recentish thing then

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.
