Useful conceptual taxonomy, not mutually exclusive mechanisms. At PDF pp. 70–71, reducing unwanted character must not be confused with chemical reduction: acrolein to acrylic acid is oxidation. Fresh all-247-sheet audit completed; source attribution does not validate every mechanism.
The chapter uses the four-part classification to connect extraction from wood with ester formation, sulfur removal, oxidation, and loss through evaporation.
Strickland organizes cask maturation into additive extraction, productive formation, subtractive removal, and reductive transformation. Oxygen, wood extractives, char, evaporation, and spirit precursors participate across these interacting classes.
