TL;DR the short pour
I built a spreadsheet to optimize my coffee, learned the optimum was “pay attention,” and had a great time anyway.
Not everything needs a return on investment. Some weekends are just for tinkering.
The setup
Scale, timer, a notebook, and far too many variables: dose, ratio, grind size, water temperature, pour pattern. I logged every cup for a week like it was a science fair project.
The finding
The single biggest factor was simply paying attention — being consistent and present beat any clever tweak. Which is, annoyingly, the lesson of most optimization.
A reminder that the personal stream here is exactly that: low-stakes, curiosity-driven, and cleanly separated from the work writing.
