Links a microscopic material property of Quercus alba to American cooperage economics and manufacturing practice: liquid-blocking tyloses permit sawing with higher usable-wood yield than splitting.
Work contrasts European and North American white oaks from both flavor and cooperage perspectives.
American white oak has an inner cellular structure known as the tyloses, which block the flow of liquid. This structure allows the staves to be sawn directly from the log bolts.

Qualification from complete-source audit — September 27, 2026
The quotation and locator remain verified as Work's words. This does not validate every anatomical explanation in the surrounding chapter. Retain the bounded manufacturing connection; do not teach tyloses as uniquely American or repeat the chapter's conflation of cambium, sapwood and radial transport. The full Literature Note now identifies these limitations and a USDA wood-anatomy reference. Stave yield is process-specific, not a biological constant.
