Can you americans help me understand the difference between bourbon and Tennessee whiskey?
Wikipedia says its because of some filter.
There ain't none to speak of. "Tennessee Whiskey" is an appellation label. In order to be called "Tennessee Whiskey", it must be a straight bourbon whiskey produced within the bounds of the State of Tennessee, and follow the quality and production standards set by Tennessee Law. Basically, it's righteousness in materials and use of a charcoal filtration step. That's it. It's basically the result of a quality standard imposed on bourbons, by the State of Tennessee.
It used to be a near certainty that bourbon was distilled / aged in Bourbon county, Kentucky. Over the years, that label has been applied to other locales, to the sometimes shagrin of those in Bourbon county, that envisioned a mortal lock on the namesake of the whiskey. "Jack Daniels", a popular mid-range whiskey tastes a lot like bourbon, but is a 'Tennessee Sour Mash Whiskey'. It's all about the provenance. But a rose with any other name would smell the same, no?
