Bourbon whiskeys can only be brewed in Bourbon county, Kentucky. I know that much at least. I didn't know about the charcoal filtering difference and I was a little fuzzy on some of the rest. Pointing out the specifics does help me figure out exactly what to get as a replacement.
My main point is, I have 7 different kinds of whiskey (Jack Daniels, Jim Beam, Wild Turkey 101, Johnnie Walker Red, Crown, Seagrams VO, Chivas Regal. I had 9, but I drank the Bookers and Military Special recently), but nothing really comparable to Jack Daniels when I run out. I guess I want another sour mash whiskey, possibly from Tennessee that is of good quality and fair price. I've had some mighty poor liquor in the past, some of which was quite expensive.
Jack Daniels went from about $22 a handle (1.75 liters) to about $65 a handle in just about 3 years.
