What kind of an espresso machine do you use? Do you think that would make a difference?

Ellie, that's a good angle to approach it from. I have a LM Linea 3gr.
I was sure it was the la Marzoccoo baskets for the portafilters.... because they are kinda goofy shaped....and then we tried oversized baskets, etc. etc.
but I have also heard it is an issue for a lot of people.
Hence the evolution of an almost unwritten rule pull doubles even for a single drink.
I am sure there are Barista out there that have overcome this issue (Change the grind, adjust the tamp, different dosage)
I just have not really tried that hard, after talking with my roaster (I also bought my machine from him, so we spent a couple days together fine tuning everything) and he said I'll send you an extra few pounds a month for free....so "His" coffee does not taste bad.
I admit it....I'm not that good, I'm just a business owner....who makes better coffee than anyone else in my valley

so I just keep pouring shots down the drain....or me.
what machine do you own Ellie?
Good luck,
