Relative volatility can vary with composition in real mixtures, so predicting ethanol–water–congener separation requires appropriate vapor–liquid-equilibrium, activity-coefficient, and enthalpy data rather than constant-volatility assumptions alone.
Vogelpohl establishes the general requirement but does not supply whiskey-specific congener data or validate any particular American-whiskey still.
This is the methodological guardrail for translating ideal distillation diagrams into technically responsible whiskey explanations.

Atomic idea
Relative volatility can vary with composition in real mixtures, so predicting ethanol–water–congener separation requires appropriate vapor–liquid-equilibrium, activity-coefficient, and enthalpy data rather than constant-volatility assumptions alone.
Reasoning
This is a methodological guardrail for translating ideal distillation diagrams into technically responsible whiskey explanations.
Provenance
Vogelpohl’s Distillation: The Theory supplies the current technical provenance through LIT-109 and its verified excerpts. The node remains Developing until another independent technical source corroborates it.
Counterpoint and limit
Vogelpohl establishes the general requirement but does not supply whiskey-specific congener data or validate any particular American-whiskey still.
