This might be a rather silly question but I remain quite perplexed as to what is going on...
I have a Sunbeam EM0480 and a Rancilio Rocky. When I grind beans on the EM0480 for a Rancilio Silvia double basket, I am usually able to get a pretty spot on dose by allowing the grinds to heap in the basket, knocking the portafilter once to allow the beans to settle, then using the flat edge of a spoon to push the excess grinds out such that the grounds sit flush with the top of the basket. After that, I apply about 30lbs of tamping pressure, and that usually packs the grinds down to the ridge line of the basket.
However, when using the same method of dosing (levelling off) and tamping (30lbs) on my newly acquired Rocky, I find that the packed grounds sit higher than the ridge line, which suggests to me that the dosing is too high. Why is this happening? What am I doing wrong? Really appreciate if someone could advise me. Sorry for being a total noob!
