Context before verdict
“Sulfurous” is a broad sensory family, not a diagnosis. Different sulfur compounds can smell different, and some low-level sulfur expression can be process- or style-contextual.

These are evidence-backed possibilities, not deterministic troubleshooting diagnoses.
Style context
Where this descriptor can be characteristic
