Book(s)Core summary
Bouchard Cooperages links American white oak’s vessel-sealing tyloses to lower permeability, the ability to saw staves without leakage, and more than double the stated stave-wood yield per log.
Author argument
Because tyloses seal American white oak’s pores and vessels, the wood can be sawn rather than split along the grain. Bouchard presents the resulting yield advantage as a major reason American oak barrels cost less than French oak barrels.

Bouchard links American white oak tyloses to sawn watertight staves
Researcher synthesis
The source independently validates ZET-6’s anatomy-to-cutting-to-yield chain. It also clarifies the boundary: tyloses support manufacturing suitability and liquid tightness, but do not by themselves establish flavor superiority, a legal requirement, or universal barrel economics.
Assessment
Strength: exact practitioner corroboration of the causal sequence from anatomy through stave conversion to log yield.
Boundary: commercial, wine-focused, undated FAQ with no log geometry, grading rules, sample size, calculation method, raw data, or uncertainty. The “over twice” magnitude remains attributed.
