A column attached to a batch pot still receives a changing feed, and its internal inventory delays how changes appear in collected spirit.
Literature Note
Chapter 8 combines the changing batch pot with repeated contact in a column. Trays or packing, internal holdup, reflux and takeoff interact. The existence of many plates does not convert a changing batch into a steady continuous process, nor guarantee a particular purity under every condition.
The discussion of stabilization and takeoff is useful conceptually, but its temperatures and plate-count heuristics are not universal settings. Pure-component boiling points do not identify a mixture's cut points. A 20–30% charge cannot generally be treated as though the whole pot boils at pure ethanol's temperature. Flooding, entrainment and loading require the more precise engineering treatment represented elsewhere in the library.
Neutral-spirit examples are comparative. The book's US vodka definition predates the 2020 removal of the old distinctive-character wording, and its EU regulation reference is also historical. Neither should be copied into the American-whiskey classification lesson as current law. A worked example at high distillation and barrel strengths likewise does not establish bourbon compliance.
Extractive and salt-assisted examples show that solvent composition can alter relative behavior, but not that every congener becomes more volatile in the same direction. The pear-spirit salt study raises composition and corrosion tradeoffs; it is not a recommended whiskey method. The main contribution is systems thinking: a control change has a response time and affects more than one outcome. The supplied scan repeats this entire 23-page chapter; it was reviewed once as unique content and indexed once.

Additional Visual Audit — 28 September 2026
Additional visual inspection: p.225 uses 'solid-state conditions' in a discussion of stable operating inputs. Do not repeat that phrase as a physical phase description or claim the batch composition is constant. Figure8-2 p.236 repeats conditional relative-volatility trajectories rather than establishing universal settings.
