A durable systems statement: distillation is selective transformation, not simple purification. The book’s later azeotrope explanation is misleading and should not be reused without correction. The automatic-removal-of-toxins wording is not a safety guarantee. Page 137 conflates azeotropic composition with vapor from any ethanol-water mixture; concentration basis must be specified.
The discussion introduces boiling behavior, copper, automation, and the sensory goals that determine how a still is operated.
Bryson frames distillation as three simultaneous jobs: raise alcohol concentration, remove undesirable or unsafe compounds, and retain desirable congeners created during malting, mashing, and fermentation.
