Direct American-whiskey evidence for comparing stills by feed, operating mode, separation levers, and target profile rather than craft prestige.
The passage follows the schematic of a bourbon beer still with attached doubler and turns from material flow to the control limits of the system.
Wright and Pilkington describe the conventional American beer column feeding a doubler: the second distillation raises proof and increases copper contact. They also explain that the simple continuous system offers limited profile adjustment through trays and reflux, whereas batch pot redistillation can alter heads and tails cuts to create a wider range of profiles from the same base spirit.

Evidence

A simple continuous arrangement offers limited adjustment through trays and reflux, while batch pot redistillation can alter heads and tails cuts to create a wider range of profiles from the same base spirit.
Location and context
Chapter 7, Distillation; printed p. 101 / PDF sheet 291. The passage follows a schematic and shifts from material flow to the control limits of the system.
Annotation
This supports comparing stills by feed, operating mode, separation levers, and target profile rather than by a craft-versus-industrial hierarchy.
