Anyone got any observations about what i need to change when using a puck screen?
Just pulled today’s dosage and it ran ‘tighter’ and needed a good few seconds added to the overall time.
Should i just grind coarser or look to retime on the original grind setting, what’s best?
Tasted ok to me but there again i drink milky drinks so i’d guess thats masking a few (lot) of the underlying problems with the shot..
As an additional screen will introduce more resistance you could grind coarser but you would be better guided by taste.
So, adjust time?
I personally did not have to do any changes and if I removed the screen the coffee (both volume and taste) do not change.
The tightness might be linked to the size of your basket and how much you dose in.

No.
Same bean, same basket but now with puck screen, same grind, same shot settings, much slower flow, hmm?
The puck is getting compressed too much so that the water cannot flow through. The puck screen takes space and is not allowing the puck to expand.
Use a deeper basket and do the same - you’ll see the shot will flow normally again.
The puck screen doesn’t restrict the flow as such. What restricts the flow is because there’s no headspace for the puck to expand.
Put a £1 coin on top of the tamped puck, lock the PF, remove it, and then check if there’s an indentation. If there isn’t, then it’s good. Now put a 10p coin on top. If you get an indentation, then you need to lower your dose as the 10p coin is thickness of the puck screen… actually slightly thinner.
Thanks.
This is a ‘slim’ puck screen but then i’m willing to give anything a go. I was dosing 18gm into an 18gm basket so i can see the logic in what you say. I could try going to a deeper 20gm basket first as you suggest, its deeper by a good way.
skylark - ah. Ok, I did t know it was the slim one, sorry. I haven’t used one of those in a long time, nor have tested it out, so no idea. 👍
skylark What @MediumRoastSteam has suggested is an excellent way to solve your issue. Having 20 g basket will definitely help it. Please share observations.

Out of interest whats a reasonable amount of headspace? If you’re dosing the suggested dose into the correct basket then there must be room or doesnt it work that way? I’m guessing that some coffees expand more than others so unless you are ‘wise’ then there’s scope for this to happen with any coffee. Adding the puck screen will just comp und the problems.
skylark - my understanding is that a 10p coin is a good headspace.
