[Homeroast] Is it just me?

The Industry does in fact have a very precise system with a color to number
reference system for coffee roasts. I know it's been mentioned on List many
times. Implemented using either an Agtron spectrophotometer costing I don't
know how many thousands of dollars or the SCAA/Agtron Roast Color
Classification System set of 8 colored disks, petri dishes and instruction
manual costing $295/$195 SCAA non-member/member respectively.
How do you propose a home roaster (who also does NOT happen to be a chemist)
determine sugar caramelization or organic converted to carbon percentages? I
do hope you jest. If someone can't figure out how to communicate roast
levels with the tools Tom's provided there's something very cognitively

Ultimately the quest for Koffee Nirvana is a solitary path. To know I must
first not know. And in knowing know I know not. Each Personal enlightenment
found exploring the many divergent foot steps of Those who have gone before.
