Treat the result as conditional on new charred American oak, spirit composition, warehouse, climate, and study design. Fresh audit: Conditional trend retained. PDF323 prose says four years while Figure8.52 caption says six years; verify the primary study before reusing an exact duration. More extraction is not necessarily greater quality.
Review of barrel-entry-proof experiments and their analytical outcomes.
Across cited multi-year American whiskey studies, higher barrel entry proof generally produced lower color, dissolved solids, acids, esters, tannins, and total extract when samples were compared at a common proof.
