Research Notes
Observations from the roasting room, case studies, and quarterly summaries. What is documented here is not conclusions, but the research process itself. Notes are currently being organized and will be published soon.
-
Finding the Window Without Crack
A No Crack Roast and Cup-Driven Maturity case showing how Day 4 cup behavior can confirm maturity without relying on crack, color, or appearance.
-
When the Peach Disappeared
A crop-year sensitivity case showing how white peach identity can disappear when a coffee falls below its confirmed cup reference window.
-
Negative RoR Has Two Kinds
A falling or negative Rate of Rise is often treated as a roasting problem to be avoided. In our system, it is sometimes the intended outcome. The question is not whether RoR is negative. It is why.

What Alive Cup Is Not
Alive Cup can be misunderstood as complexity, intensity, or a long finish. This note clarifies the boundary between true structural state transitions and surface-level variation.
-
Why Caramelization Divergence Matters
Some cups speak through one kind of sweetness when hot and preserve a different kind of sweetness after cooling. CDV proposes that this is not coincidental , it is a function of where caramelization energy was distributed during the roast.

Why First Crack Is Not Always the Maturity Boundary
First crack is one of the most useful reference events in roasting, but it is not always the same as cup maturity. Some roast paths show meaningful cup maturity before conventional first-crack confirmation. Others pass first crack while still lacking structural maturity in the cup.
