Jack Daniels is NOT bourbon - it is a "bourbon style whiskey".
Actually, it isn't a "bourbon style whiskey." It is Tennessee whiskey, which has its own unique legal standard. The difference is that Tennessee whiskey goes through a charcoal filtering process (called the Lincoln County Process) which is different from Bourbon.
Jack Daniels is a "sipping whiskey" instead of bourbon for only one reason, it's made in Tennessee.
Not quite. A "sipping whiskey" isn't from a particular location. It denotes a whiskey that ought to enjoyed by itself, rather than bastardized with mixers. Bourbon can be made anywhere in the United States, not just Kentucky.
My favorite day to day sipping whiskey is W. L. Weller Special Reserve.
