chlorox I imagine that in order to achieve that sort of control a new lever grouphead would need to be designed that can immediately control by demand the exact volume of water that is allowed to enter the grouphead on every pull
Well… if you do that, then there will be air in the group. Anyone who uses or used a la Pavoni before know about the “spongy” pull effect.
I imagine that would be a danger of that. Personally I don’t really require such a capability in a lever though it would be nice to be able to change the spring pressure on demand without dismantling the grouphead as per how the idrocompresso is supposed to be able to do
The bit I do not understand, and please can a Nurri owner explain to me…..you can vent a single group machine which technically speeds up the operation by a few seconds……so what? The research Dave s doing is to assist multi group machines where saving a few seconds per shot really does count. So, unless you have a queue at your door, and we assume that the venting idea does not actually have an effect on the taste of the shot, then I simply do not get it (yet!).
In addition, I accept that the vent removes the water on top of the puck but what about the ater within the puck?
tompoland if I could do it without wasting that water, that would certainly be better.
I suspect that’s impossible, as the amount of water into the brewing chamber is determined by the volume left by the piston; so much ends in the cup, so much is soaked up by the puck. What’s left is wasted - in the sense that even if it would be possible to re-route it to the tank, it would have been in contact with quite a lot of stuff for a bit, and I personally would not want it ‘back in the circuit’.
chlorox this is the exact reason i dont own and wont own a refractometer, and i also think companies prey on this, pushing boundries etc
theres a massive study showing how groups of experts couldnt taste the difference lol

Its just an additional way to terminate the shot and avoid the poorertasting flow at the end of the shot from getting into the cup. So if u have the nurri and you want to cut the shot, either you use the left paddle or you use the tupperware technique or you remove the cup altogether and let it drip into the driptray. If you have a conventional lever, you can use the last two options. It’s just about havingoptions and as a matter of practice, for me, using the left paddle is a nicer and easier option than doing the other two.l ways.
chlorox Ah right……sounds like the marketing men have been in the building again! Sorry, but we are splitting the atom again! Exactly the same thing is achieved whether you vent or pull the cup away and capture the excess. Of course, which method you prefer is totally personal choice but I thought the important thing with making coffee was the taste!
Let me try one more time again. It is not just marketing - it does improve the taste precisely by terminating the shot. Cutting the shot at the right time improves it. As I said, the left paddle gives you an additional way to terminate the shot. Do u absolutely need it? No, because u have the other two ways if u have a conventional lever. But it gives u a third option and for me, that third option is a nicer, more convenient, easier and more leisurely way of cutting the shot than the other two.
At some point you will either have to take my word for it or you need to try a nurri for yourself. Those paddles may grow on you…:)
personally ive found my work flow to be fine interms of taking the pf out when the next shot is ready but i have 3 no 4 pf, by the time ive ground, prep and tamp the next shot the lever has done its thing,
i think its a great idea for when you choke a lever, as that can get dangerous/messy if you dont know what to do

Sounds a bit sarcastic David (no doubt unintended) but as you know there is workflow too.
We’ve got multiple people here who actually have a Nurri who all report that they like the feature and find it a useful addition.
Then we have the pople who haven’t used a Nurri and say they cant see the point. That’s fine.
Me, I really don’t care if anyone thinks it’s a great thing to have or not.
Its been done to death. Can we move on?
All this focus on.the left paddle and we haven’t even talked much about the right paddle which is a cool hands-on way of controlling the preinfusion pump. And the user can do so at any time - even using the pump entirely independently of the lever. I suppose one could design a button to be usedinstead but where’s the fun in that?!
To me, one quality that I enjoy about the nurri is how its design is integrated and everything works together to enhance the enjoyment of simply using the machine. The paddles are part of the design in a unified and aesthetically pleasing way.
agree we need more discussion on the other features, theres not much on youtube etc yet

chlorox . If it can also be possible to easily change the spring pressure on demand as well, the possibilities would be mouthwatering…
I believe, from what I’ve read, that you can change both the pre-infusion spring pressure and the maximum spring pressure on the La Marzocco Leva as and when you like.
