Roasting Research Archive

SUNNY M Lab documents roast behaviors that operate outside conventional industry assumptions — cup phenomena, roast conditions, and the terminology we use to describe them.

This work does not rely on first crack as a primary development marker, nor does it depend on color as a fixed indicator of roast level. Instead, it focuses on how different roast conditions translate into distinct cup structures.

Across repeated trials, certain roast profiles show a high degree of consistency — predictable cup structures, recognizable temperature behavior, stable sensory arcs. These observations suggest that, while coffee varies by origin and processing, there are underlying patterns that can be explored and documented.

This archive exists to document those observations, define the terms we use, and build a searchable record of phenomena that, to our knowledge, have not been formally described elsewhere.
