Cuprajake probably has no bearing on taste but that last 9ml into the cup is coming out of the group under no pressure
I suppose it’s an easy experiment to do taste wise for the Nurri owners. Try a coffee one with venting the group one without it and see what the difference in taste is.
I doubt it has any adverse impact on taste.
I don’t flush the grouphwad before shots.
Maybe I am less discerning but there is a boundary beyond whixh coffeemaking becomes too microscopic for me and it becomes stressful rarher than the relaxing routine that it is suoposed to be for me. If those last few dribs after i cut the shot can make such a big difference to turn a great shot into a poor shot, then I’m not noticing that and if I’m not, maybe it isn’t really having any discernible impact. If it is having some impact, then maybe I actually ike the difference that it is making. Either way is fine with me …
As i said before, I periodically use the tupperwqre technique instead of venting with the same beans. I don’t taste any difference.
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?
