Cuprajake
First shot ran faster at 22s; Group 89, brew 95. The group was at 88.1 (ouch!) when I locked the lever. Nice but bitter .
Second shot lasted 29s. Group 90.5, brew 96.5. The bitterness was gone. Perhaps, it was a shade sharper. May drop the group temp to 89.5-90.0 and see. I am thinking if the shot still ran faster. It is a medium dark, though. I don’t think I will tweak much from here. It’s a nice cup.
