Age is confounded with production date and barrel. No samples inside the first two years establish the timing of change; no sensory maturity threshold follows. Figure 2 formula counts are not monotonically increasing at every age.
Claim captured during full page-by-page processing of the supplied source.
Across samples of different ages, production dates and barrels, the authors report their largest compositional difference between unaged spirit and two-year bourbon. This is not a controlled longitudinal age series.
