Isn't that alittle low? I find at least a 16g for a double shot taste better
Some cafes dose up till 20g too
I have problems packing in more than 15gm into the Poemia (53mm) pressurised portafilter. At 15gm it's a full dome already... people say that you are not supposed to hard tamp a pressurised, so how to fit so much grounds?
Furthermore, even at 15gm I seem to get some overextraction/bitterness. When I increase the grind size, I seem to reduce the body. For me, 13gm at the grind setting I use gives a nice balance.
I was hoping to get some advice from people who have been using the Poemia for a while on how to max out the taste. Lately I've been holding the portafilter in the "locked" position until the coffee begins to dribble out, which seems to increase the infusion time by a couple of seconds; however along with the increase in body, a bit of bitterness creeps in (which in a latte/macchiato is well controlled).
Now I'm seriously considering hacking the machine (and thus voiding the warranty) and piece together a PID controller to keep the temperature more consistent throughout the brew cycle. This involves a HUGE learning curve for me, as I have never done that serious an electronics project before.
Poemia & other single boiler pressurized gurus, please advise.
