Strong process synthesis, but particular chemical pathways and magnitudes need primary technical corroboration. Treat the 20-minute reproduction interval, genetic-memory metaphor, and starch-to-flavor arithmetic as simplifications requiring correction.
The chapter uses producer examples, especially Four Roses and sour-mash fermentations, to show that fermentation is a flavor-design stage.
Bryson explains that yeast strain, pitching rate, temperature, fermentation duration, and bacterial activity alter alcohol production and the precursors, acids, esters, phenols, and other compounds carried forward into distillation.

2026-09-29 fresh full-source text and visual review: supplied 2025 PDF, 368 sheets. Body and properties reconciled to the checked PDF range; these are not print page numbers. Verified means source fidelity, not independent validation of the source's claims. Prior locator history: 2026-09-16: Reader locator verified by chapter/section; internal retrieval starts at PDF sheet 113, relevant chapter/section coverage through sheet 127. Page is an internal PDF coordinate, not a printed page. Previous locator PDF p. 93–PDF p. 103 is superseded. This verifies the location, not independent accuracy of all source claims. Earlier notes: The stated page range was checked against the full extracted text; representative pages were also visually checked against the rendered PDF on 2026-08-26. This record paraphrases the source and preserves its scope.
