Excellent question and the root our dilema discussing coffee roasts. I've
developed my descriptions primarily from two sources, both I consider Coffee
Professionals and Experts in the field: our Tom & Kenneth Davids.
Unfortunately they don't agree!!! Or rather their descriptions don't seem to
completely agree. Seehttp://www.sweetmarias.com/roasted.pict-guide.html&
"Home Coffee Roasting Romance & Revival" page 68. Tom's 'Full City on the
ligher side' ranges from 415-425°f and 430-445° 'Full City on the dark side'
and states 2nd around 446°f . This sounds like FC can be before 2nd crack to
me. KD has City 415-435°, Full City 435-445°f and shows 2nd crack between
City & Full City - 435°f dividing point. Method of temp' measuring
difference maybe? By Tom's definition yes pre-2nd crack, just before 2nd
crack, fully developed 1st crack, is Full City on the light side. I call my
435° light full city (when using long 1st crack development, 7-8min) 440°f
full city. While the same bean roasted in the same Caffe' Rosto under
constant 120v would have come to 435° around 7min total time, instead of
11-12min profiled total time, and appreared about the same external color,
but ground lighter, more likely city in my understanding of the definitions.
I'm getting bored and confused and frustrated trying to explain myself so
everyone else must have stopped reading this by now...:-)
Communication via email sucks sometimes. How about a huge conference call to
really discuss it!
