It's blend of three types of whiskey: Scotch, Tennessee, and Kentucky.
Since you're blending the whiskeys, I would not use a high priced single malt Scotch whisky. Instead go for a cheaper Scotch, like Dewers, Chivas, or Johnnie Walker.
Here's my recommended "Three Wise Men" cocktail:
1 part Scotch Whisky (Chivas).
1 part Tennessee Whiskey (Jack Daniels).
1 part Kentucky Bourbon Whiskey (Jim Beam).
You can go neat or on the rocks. Whichever you like. Enjoy and be careful not to drink too many of these. Id so, you could quickly go from being a wise man to a fool.
PS: A variation is "Three Wise Men and a Baby." Same recipe as above but with a splash of milk or egg nog. This adds "holiday flavor."
