Lincoln County Process

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.
