As an expert sommelier and brewer, I can confidently say that Tennessee bourbon does not exist. While Tennessee whiskey does meet the federal definition of bourbon, it is important to understand the distinction between the two. Tennessee whiskey is a specific type of bourbon that undergoes an additional step known as the Lincoln County Process, which involves filtering the whiskey through charcoal.
The federal definition of bourbon requires that it be made from a grain mixture that is at least 51% corn and aged in new, charred oak barrels. These requirements are also met by Tennessee whiskey. However, Tennessee whiskey goes a step further by subjecting the distilled spirit to the Lincoln County Process, which involves filtering the whiskey through charcoal made from sugar maple trees.
The Lincoln County Process is a unique aspect of Tennessee whiskey production and is mandated by state law. This process is said to impart a smooth and mellow flavor to the whiskey, distinguishing it from other bourbons. The charcoal filtering is typically done before the whiskey is aged in barrels, allowing it to interact with the oak and further develop its flavor profile.
While some may argue that Tennessee whiskey should be considered a separate category from bourbon due to the Lincoln County Process, it is important to note that it still meets all the requirements to be classified as bourbon according to federal regulations. Therefore, it can be considered a type of bourbon.
In my personal experience, I have had the opportunity to taste a variety of bourbons, including Tennessee whiskey. Each has its own distinct characteristics and flavor profiles, influenced by factors such as the grain composition, aging process, and filtration methods. Tennessee whiskey, with its charcoal filtering, does have a unique flavor that sets it apart from other bourbons. However, it still retains the fundamental qualities that make it bourbon.
To summarize, while some may argue that Tennessee whiskey should be considered a separate category, it is important to recognize that it meets all the requirements to be classified as bourbon according to federal regulations. The Lincoln County Process, which involves charcoal filtering, adds a unique flavor and character to Tennessee whiskey. So, in essence, Tennessee whiskey is indeed a type of bourbon.
