Straight Bourbon vs. Tennessee Whiskey – What’s the Real Difference?
Straight bourbon and Tennessee whiskey are two iconic expressions of American whiskey — and while they may seem similar at first glance, key differences in production, geography, and flavor set them apart. Whether you're a whiskey enthusiast, new to brown spirits, or simply curious, Elevated Spirit Shop is here to guide you through what straight bourbon and Tennessee whiskey are, how they’re made, how they taste, and which brands to try next.
What Is Straight Bourbon?
Straight bourbon whiskey is a subcategory of bourbon that adheres to stricter aging standards. It must meet all federal regulations that define bourbon, plus a few additional requirements related to aging and additives.
Key Requirements for Straight Bourbon:
- Made in the United States
- Minimum 51% corn in the mash bill
- Distilled to no more than 160 proof (80% ABV)
- Aged in new, charred oak barrels
- Must be aged at least 2 years
- No additives or coloring allowed
Flavor Profile: Typically sweet and full-bodied, with strong notes of vanilla, caramel, oak, and baking spice. Aged straight bourbons (4–12 years) develop added depth and complexity.
What Is Tennessee Whiskey?
Tennessee whiskey is a type of whiskey made in the state of Tennessee that meets all the legal requirements of bourbon, with one crucial addition: the Lincoln County Process — a charcoal filtration method that softens the whiskey before aging.
Key Requirements for Tennessee Whiskey:
- Must be made in Tennessee
- Must meet all legal criteria of bourbon
- Must undergo the Lincoln County Process: filtered through sugar maple charcoal before aging
- Must be aged in new, charred oak barrels
Flavor Profile: Similar to bourbon but often smoother and slightly lighter, with mellow oak and sweet caramel characteristics. The charcoal mellowing adds a distinctive smoothness.
Straight Bourbon vs. Tennessee Whiskey: Side-by-Side Comparison
| Feature | Straight Bourbon | Tennessee Whiskey |
|---|---|---|
| Geographic Requirement | Anywhere in the United States | Must be made in Tennessee |
| Main Grain | Minimum 51% corn | Minimum 51% corn |
| Aging Requirement | Minimum 2 years | No specific minimum, but follows bourbon rules |
| Charcoal Filtering | Not required | Required (Lincoln County Process) |
| Barrel Type | New, charred oak barrels | New, charred oak barrels |
| Additives | None allowed | None allowed |
| Typical Flavor | Bold, sweet, spicy, full-bodied | Smooth, mellow, slightly sweeter with less bite |
What Is the Lincoln County Process?
The Lincoln County Process is a filtration step unique to Tennessee whiskey. After distillation, the spirit is slowly filtered through thick layers of sugar maple charcoal before it enters the barrel for aging. This extra step removes impurities and softens the spirit, contributing to the smooth, mellow taste Tennessee whiskey is known for.
It’s this process that sets Tennessee whiskey apart from standard bourbon — even though both share nearly identical ingredients and aging techniques.
