Distillation turns a fermented base into a spirit by separating and concentrating volatile components, especially alcohol.
The simple model does not describe equilibrium, azeotropes, congeners, reflux, or cuts; additional technical sources are required.
This separates fermentation and distillation conceptually, improving retrieval for production questions and preventing the two stages from being conflated.
The 2025 CSS Study Guide supplies the technical baseline; Kosar independently corroborates the fermentation-to-distillation sequence and vapor-condensation description at printed p. 12 / PDF sheet 14. Pilot-era title normalized and node advanced to Established in Batch 025 on 2026-08-25.
Distillation begins with a fermented liquid; it does not create alcohol from unfermented grain.
Atomic idea
Distillation turns a fermented base into a spirit by separating and concentrating volatile components, especially alcohol.
Reasoning
Fermentation first creates alcohol in a grain-and-water base. Distillation then heats that liquid, routes vapor through the still, and condenses a selected portion into spirit.
Provenance
The CSS Literature Note supplies the technical baseline. The Kosar Literature Note independently corroborates the sequence and introductory vapor-capture description at printed p. 12 / PDF sheet 14.
Counterpoint and limit
The simple model does not describe equilibrium, azeotropes, congeners, reflux, still geometry, or cuts. Those mechanisms remain in separate technical nodes.
Maturity checklist
Kosar full-copy audit qualification
The correct fermentation-before-distillation sequence is retained. Kosar PDF21–23 incorrectly describes alcohol evaporating without water and confuses column plates with the final condenser. The sequence corroboration must not be extended to those mechanisms. His Coffey diagram also lacks its letter key. Full critique: Whiskey as production system, regulated category, and historical institution — Kosar. This supports using a verified vapor/liquid equilibrium diagram alongside the bounded atomic idea.
