Not sure about the ROK in particular, but manual lever machines can be a bit tricky to dial in given the additional variables at play. Not sure if there are any ROK forums out there that you can check out for tips. Might be worth buying a bag of something not too expensive and doing a bit of playing around with grind size, dose & pressure and see what works best for you.
Had a quick look there and spotted that it comes with a scoop/tamper, and no actual dedicated tamper. Probably a good idea to pick up a dedicated tamper if you haven't already though. Found a list here but a lot of the links point to out of stock items, probably a good starting point though: https://cooklikechuck.com/2016/08/22/tampers-rok-espresso-maker/
I am looking for a 49.7mm tamper.
That is a lie, I haven't looked at all, i was hoping someone can point one at me.
I have a ROK presso that I completely fail to make good beverages with, so am looking to get "all the gear" to accentuate my "no idea"
