Use Work 2014, printed p. 126 / PDF p. 128 for the anatomy-to-sawing relationship and printed p. 136 / PDF p. 138 for yield and mechanization.
Liquid-blocking tyloses in American white oak help sawn staves remain watertight, allowing coopers to cut staves directly from log bolts.
Both Work passages were visually verified on 2026-08-24. The first identifies liquid-blocking tyloses and sawn staves; the second specifies the yield and mechanization consequence.
The claim is about stave suitability and production method, not flavor superiority or the legal requirement for bourbon barrels. Bouchard’s “over twice” yield magnitude is commercial testimony without disclosed calculations and should be attributed or omitted.
Work supplies the causal chain from tyloses to leak resistance, sawn stave production, higher usable-wood yield, and mechanization. Bouchard Cooperages independently corroborates the tyloses-to-sawing link and attributes a per-log yield advantage to sawing.
Retained at Ready for Drafting / Strong / High after EXT-315–EXT-316 independently corroborated the anatomy-to-sawing mechanism and added an attributed practitioner yield comparison.
Evidence judgment
Two visually verified passages from Work establish the source-bounded causal chain from liquid-blocking tyloses to sawn staves, higher usable-wood yield, and mechanization. 
Drafting guardrail
Use the bounded statement that tyloses help make sawn American white-oak staves viable. Do not convert manufacturing suitability into flavor superiority or a legal statement. Attribute or omit Bouchard’s “over twice” yield magnitude because the FAQ discloses no calculation method.
