Sunny M Lab is a coffee roasting research archive documenting roast behaviors that operate outside conventional industry assumptions.

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, with tightly grouped temperature behavior and predictable cup outcomes. These observations suggest that, while coffee varies by origin and processing, there are underlying patterns that can be explored and documented.

The goal is not simply to produce good coffee, but to identify profiles that create a clear sensory identity — cups that show distinct behavior at different temperatures, and remain memorable beyond immediate taste.

This archive exists to document these observations, define the terms we use, and create a searchable record of a roasting approach that is still being explored.
