TN whiskey is not that good.
If burrbinzz wasn't king then the Irish and Scotts wouldn't need their leftover barrels to get some of the bourbon in their product to make it drinkable.
That sounds like a nice marketing catch phase for Bourbon makers. Too bad that ain't why they buy them.
They do buy and use the barrells from Kentucky for Scotch and Irish Whiskey but its only to meet demand in those countries. Their whiskey is typically aged longer on average. Realtive to the size of those 2 countries, the amount of whiskey made there is astronomical. Bourbon, by law has to be aged in NEW American White Oak barrels. Since it typically doesn't age nearly as long as the other 2 styles, turnover is a lot higher. The reality is, America has a shit ton more wood and barrels at their disposal than does Ireland or Scotland as well. It makes perfect sense really.
International Whiskeys:
JAMESON = 30 million bottles sold yearly.
Johnnie Walker = 130 million bottles sold yearly. (biggest selling spirit in the world, period)
Chivas Regal = 55 million bottles sold yearly.
Thats a LOT of demand coming out of 2 countries that have less than 10 million people combined. And those are just the Big 3.
Other notables from a 300 million people populated country (US) for comparison sake:
Jim Beam = 72 million bottles sold yearly (biggest selling Bourbon in the world)
Jack Daniel's = 120 million bottles sold yearly (biggest selling United States whisky)
Some rarer ones:
Knob Creek = 2.5 million bottles sold yearly.
Woodford Reserve = 1.9 million bottles sold yearly.
