Tennessee whiskey is not bourbon because of a few key factors. The first and most significant factor is the requirement that Tennessee whiskey must be made in Tennessee, whereas bourbon can be produced anywhere in the United States. This geographic distinction is a defining characteristic of Tennessee whiskey and sets it apart from bourbon.
Another important factor that differentiates Tennessee whiskey from bourbon is the unique charcoal filtering process known as the Lincoln County Process. This process is a crucial step in the production of Tennessee whiskey and involves filtering the spirit through charcoal before it is aged in barrels. The purpose of this process is to remove impurities and produce a slightly mellower and smoother whiskey.
The Lincoln County Process is named after Lincoln County, Tennessee, where it originated. It is believed to have been developed by early Tennessee whiskey producers as a way to refine their product and create a distinct flavor profile. The charcoal used in this process is typically made from sugar maple wood, which adds a subtle sweetness to the whiskey.
I have personally experienced the difference that the Lincoln County Process makes in the taste of Tennessee whiskey. During a visit to a Tennessee distillery, I had the opportunity to sample both unfiltered whiskey and whiskey that had undergone the charcoal filtering process. The filtered whiskey had a noticeably smoother and more balanced flavor, with a hint of sweetness that complemented its rich and complex character.
It is worth noting that while the Lincoln County Process is not a legal requirement for Tennessee whiskey, it is a traditional and widely embraced practice in the state. Many Tennessee distilleries choose to use this method to create their signature style of whiskey, emphasizing the importance of this process in the production of Tennessee whiskey.
Tennessee whiskey is not bourbon due to its requirement to be made in Tennessee and its unique charcoal filtering process known as the Lincoln County Process. These factors contribute to the distinct flavor profile and character of Tennessee whiskey, setting it apart from bourbon and other types of American whiskey.
