The
Lincoln County Process is a step used in producing some
Tennessee whiskeys. The
whiskey is filtered through, or steeped in,
charcoal chips before going into the
casks for aging. The process is named for
Lincoln County, Tennessee, which was the location of Jack Daniel's
distillery at the time of its establishment; subsequent redrawing of
county lines means that none of the distilleries currently using the process is located in the
county for which the process is named.
