Roast feedback
Real feedback on every roast.
You've wanted feedback — you've posted on Reddit asking for it. Now you get it on every roast, instantly, and sharper the more you roast. Not AI guesswork: assessment on the axes roasters already trust. Works on imported Artisan logs, no hardware required.
Rate of rise dived to 6°F/min around 9:15 — 11°F/min below where it sat at first crack.
Ease the heat before first crack so the rise glides down through development.
From one roast
Instant defect read
The moment a roast lands, imported or logged live, First Crack flags what it sees. A crash after first crack, a stalled bake: named, located on the curve, with the consequence and the fix. On roast number one, no setup.
From many
Consistency you can measure
Roast the same bean again and a score tells you how tightly your repeats land, which roast broke pattern, and on which axis. The feedback sharpens the more of the same bean you roast.
Side by side
See it, overlaid
Stack up to four roasts on one chart. A tight bundle or spaghetti — consistency reads instantly, no numbers required. Share the comparison with a link.
Known axes, not a black box
The things roasters already argue about.
Every read traces back to a number you can see on the curve. We surface what we find most meaningful, then let you examine the axes yourself: widen the comparison, tighten it, slice by roast level. Deterministic and explainable.
RoR crash / flick
A sharp dive in rate of rise after first crack — the canonical baked, hollow defect.
Stall / bake
Rate of rise flatlining through development — flat, papery cups.
Charge temp
How consistently you start, batch to batch.
First-crack timing
Where FC lands as a share of the roast.
Drop temp
Where you pull — the biggest lever on roast level.
Development ratio
Time in development versus the whole roast.
