Bottling proof alone cannot establish how much a whiskey was diluted after maturation.
The book provides case accounts, not measurements for every batch. Normalizing trial proof remains useful but cannot reconstruct production history.
Jennings’s Master’s Keep 17 and Diamond Anniversary discussions distinguish relatively low bottle proofs from substantial added water. Warehouse conditions and mature-barrel proof matter. Our comparison sheets should keep entry, mature-barrel and bottling proof distinct and mark unavailable data unknown.
