What RoastSource does for it

Calibrated temperature-target profiles for the CBR-101 — set-point guidance through the roast
Preheat guidance — charge into a hot drum, not a cold one
Batch-size sweet spots for even roasts (a little under max makes a big difference)
Stretch development between first and second crack for sweetness — with timing to aim at
Plain-language defect troubleshooting — sour, grassy, baked, uneven
Inventory, ratings, blends, and coffee education in the same app

Almost always underdevelopment. The profile times your window past first crack and the defect guide confirms it from your log.

Batch-size guidance and preheat discipline fix most Gene Café evenness complaints.

Timing bands anchored to your first crack — not a generic chart.

Inventory, roasting, ratings, blends, brewing, and coffee education — offline, private, and yours.
