Earl Grey tea, iced, lightly sweetened....actually gives you a hint of a bourbon mouth feel.
I also like a club soda with a bit of FRESH lemon, it cleans the palate between puffs a bit.
Espresso anytime.
And it is hard to beat a nice, slightly fruity red wine, like a Malbec or Sangiovese.
But yeah, Bourbon or Scotch is still the way to go!
