1. Roasting Samples for Evaluation
“The sample should be roasted within 24 hours of cupping and allowed to rest for at least 8 hours.
Roast profile should be a light to light-medium roast, measured via the M- Basic (Gourmet) Agtron scale of approximately 58 on whole bean and 63 on ground, +/- 1 point (55-60 on the standard scale or Agtron/SCAA Roast tile #55).
The roast should be completed in no less than 8 minutes and no more than 12 minutes. Scorching or tipping should not be apparent.
Sample should be immediately air-cooled (no water quenching)”
This is a very good starting point. At Boot Coffee, our recommended roast profile for samples is hitting the first crack at around 10 minutes and have rate of rise around 5 degrees C so your roast development time is 1:30minutes-2:30 minutes to achieve Agtron 58.
You can create your own roast profile, but make that you roast all your evaluation samples the same way so you compare apples with apples.
