Its virgin-USA-oak requirement for bourbon conflicts with 27 CFR 5.143(c), which specifies charred new oak, not American-grown oak. Three-year maturation is not a universal American rule. Section 4.4.1 first calls polymers fully soluble, then calls lignin insoluble: preserve that internal inconsistency. Model-wine evidence is not direct bourbon proof; extraction speed is not complete maturity.
The review distinguishes addition, interaction and subtraction during maturation. Wood species, prior use, seasoning and heating affect extraction of aldehydes, phenols, lactones and tannin-related compounds.
