I have problem with weak crema, got my fresh bean from my espresso lab, bean is fresh, around 2 weeks old.

i got myself with a unpressurised basket. using my hand grinder to grind to the finest(took really long time to grind it though) , tamp it and pull the shot. Surprisingly it over tamp at the first time.

Second time adjust the grind about 1/4 turn from finest to course, tamp at the same pressure. this time still under tamp, the coffee came out too fast with very weak crema.

Im expecting myself to get a nicr crema like tiger stripe, but fail to do so, but havent give up yet. My machine is Delonghi ecov 311, since the Delinghi EC 155 wit upf can do a nice crema tiger stripe, i believe my machine can do it too.

Any idea what will be the problem? is it because of my coffee not properly grind enough? feel like wanna get an electric grinder.. tiring of grinding with my arm... lol

so need to keep try and error? cause i thought unpressurised basket need very fine texture.

EC155 same specification as Eco 310/311 right?

I plan to get a electric grinder.. welhome ZD 15/16

now im trying to use unpressurised basket.
ya, if i use pressurised i also lightly tamp , cos if tamp too much will tend to over tamp thus the water cant flow thru
