What Happened
This roast was intended as a clean baseline for Santos natural espresso.
The roast progressed normally. Crack was detected but described as individual pops rather than a rolling onset. No instability or obvious anomalies were noted.
Colour at drop was medium brown with no visible oil. The beans appeared even, with possibly the odd quaker. Aroma during roast included a popcorn-like phase typical of naturals.
Weight loss landed at 15.0%, placing it squarely in the middle of the espresso-oriented band for this machine and batch size.
Position in the Santos Arc
This roast sits:
- Above Lazy Mode natural territory (~13.8–14%)
- Below aggressive espresso development (>16%)
- In the early espresso-leaning range for Santos on this system
It represents a structured starting point for espresso testing rather than a push roast.
Open Questions (Cup Required)
- Does 15.0% provide sufficient body?
- Is acidity integrated or slightly forward?
- Does the finish linger or fall away?
- Is sweetness present without pushing further development?
This roast is the baseline reference for this coffee.
