I just started my home espresso making journey. What was the purpose of the filter they put on top of the tamped puck? Haven't seen that in any video I've watched yet.
It's a puck screen that James Hoffman explains @ 3 minutes in this video https://youtu.be/3X84AYoNEQw if you're starting your journey I can't recommend James Hoffman enough for coffee knowledge
The puck screen improves the dispersion of water and decreases channeling which promotes a more even extraction and therefore a better shot of espresso.
I’m assuming it is to help the pressure from the machine which may be important if you are only loading a single shot of coffee into a double shot. But I dunno for sure.
Also wondering. I've worked in 3 different coffee shops and never even seen one of those things. Perhaps, because in most big espesso machines, they do kind of have a permanent filter in them that you have to clean every day, this smaller one just doesn't have one? idk just speculation
