Thought of the Pepto Bismol, but it would likely clog the vibe pump :)
As far as I know the only thing that has changed amongst my beans,
grinder, technique and machine is time. Just ordered an e61 pressure
gauge, and will see what I have. I have been doing everything I could
research to fix my grind/dose/distribution/tamp, but still get squirts
and not-so-heavenly shots. I will update when I see what is happening
with my brew pressure.
I was using a ThermoWorks Thermapen, which is quite accurate. You
guys are right about the falling thru air cooling; this morning I took
the group and dropped one side while running the pump, and the water
temp went from 201 to 204 as it was running for about 10 seconds.
Temp control/display is set at 94, so I am apparently running a bit
hotter than set for. I will dial down the temp to 93 and see if my
flavor improves....
I also do not make it a habit of running any water through the head
before brewing, are you guys doing this routinely, or recommend a bit
of a flush first?
Ben, what were your observations of display/thermometer differential
using the infrared thermometer?
hello, it's a good idea to run about two ozs water thru the brew head
to heat it to the set temp. that is after the machine has been sitting
idle. -Dennis
