Kentucky's limestone geology supported whiskey production through low-iron water, reliable springs, cooling, and site suitability; it did not simply impart an undefined 'limestone flavor.'
Water chemistry varies by source and treatment, and modern plants may alter or replace historical dependencies.
The strongest historical explanation connects geology to fermentation water quality, condensation, plant location, and pre-refrigeration operations. These mechanisms are specific and testable.
Prefer named mechanisms and measured water conditions over regional mythology.
