It’s just impossible to know with pre-ground coffee for espresso, if you think that with a grinder next to your machine you’ll have to adjust about 3-4 shots before it does what you want it to. Even if the pre-ground is perfect when you get it home, it can be totally different within half an hour, let alone hours or days, as it’s exposed to the elements. But it’s unlikely the grind size will be anywhere near what you need straight off the bat.
Also I just looked at that pic again and it’s much too coarse for espresso.
Agree with all of that. I was/am just a bit surprised that the roaster sent out coffee that is quite so coarse! But yes, take o board your points, which leads me to think that pre-ground espresso grind is for pressurised baskets...
