Refining technique, getting closer to that "money shot" with the bottomless / naked portafilter. I've pulled perhaps 100 shots of coffee at this point.
This was roughly 19 grams of Roastco coffee, temperature set at 200° and a shot running approximately 30 seconds. I couldn't find details of optimal settings, so I guessed. Worked out nicely.
Note a little section I missed near the right, perhaps due to slightly uneven distribution of grounds.
