hi coffee lovers
so nice to see a whole thread and v2 too for this
just checking in...im using a Saeco Poemia with the given pressurised portafilter
is there any upgrades i can do with the poemia? or straight get a new machine? i read that the grinder is more important though - when using nonpressurised portafilter
i thought i saw someone using poemia with nonpressurised and pid somewhere here.. @lowkl
Welcome to the forum!
IMHO the Poemia is a great starter machine, as it's cheap, very simple in design, cheap, is easy to depressurize and re-pressurize if you choose, has been modded extensively (even controlled by an Arduino, with PID, pressure and volumetric control!), cheap, decent vibe motor....
Did I mention cheap as well?
The zero cost & risk mod you can do is to depressurize. It takes just just a screwdriver and less than 5 minutes. And the process is completely reversible, as long as you take care not to break any component or lose the tiny spring inside. Honestly when I started I put it back in at least 3 times as getting a decent cup was a bit of a challenge.
The largest improvement mod in terms of consistency was definitely the PID. I got a rip-off REX C100 China PID controller for about RM 60 with the SSD and k-type thermocouple, and plunged in. Problem was, the unit was so cheapo that the auto-tuning didn't work, and it didn't come with the alarm function so I couldn't get it to control the steam. However, the temperature stability is great... I get less than 4 degree variation throughout the pull. Also, multiple shots taste the same. Also, I have temperature readout to know when the machine is ready.
Drilling off the bottom of the portafilter did not improve the quality of the shots at all but provided some espresso porn only.
In terms of spending money I fully support splurging on the grinder. The quality and consistency of the shots just jumped after getting the Mignon, and at the same time the stress level dropped tremendously. I can usually tune to within 3 seconds of the targeted time within 2 to 3 shots when using a new supply of beans.
Enjoy the journey!
