How Is Jack Daniel’s Aged?

Jack Daniel’s whiskeys age inside wooden barrels in Lynchburg, Tennessee.

Aging is correlated with flavor enhancement because as the whiskey matures in the wooden barrel, it seeps through the wood and develops different flavors. The location’s heat and humidity influence the speed of the wood seeping. [1]

Their process starts with the Lincoln County process. This is a legal requirement for all Tennessee whiskeys that involves using charcoal to remove all impurities from the spirit.

What Charcoal Filtering Does To Its Whiskey’s Age

Charcoal filtering eliminates the need for an extended aging period. 

The whiskey becomes more refined as it is filtered through charcoal, meaning it won’t need to spend so much time aging inside the barrel. But how much alcohol is in a Jack Daniel’s bottle?

Jack Daniel’s Criteria For Its Aging Process

Whether The Whiskey Tastes Ready

Taste readiness is one of Jack Daniel’s criteria for whether or not the whiskeys are ready for bottling. 

After being aged four years, expert tasters sample the whiskey barrel at intervals. They evaluate its flavors to determine if it has reached the desired quality, even with a short aging period. But what does Jack Daniel’s taste like?

A Minimum Of Four Years

Jack Daniel’s establishes a minimum aging period of four years for all its whiskeys. However, it can be aged longer (up to seven years) depending on the whiskey’s development and readiness. [2]

Jack Daniel’s whiskeys stand in stark contrast to many other whiskeys that age 5, 10, 12, 18, 21 years, or even longer because they focus more on whether or not their whiskey tastes ready, as opposed to having spent a set number of years aging. 

This is considered unconventional (even controversial) in the liquor world because age is often considered a sign of quality. 

However, one key reason this short period isn’t a concern is their target market: casual whiskey drinkers.
