I'm about to add oak chips to my scotch ale. I was thinking about what sort of scotch to soak the chips in before hand. And then I thought, how much does it really matter?

At what point can one tell the difference between types of whiskey an ounce of oak chips were soaked in, when they've been sitting in 5 gallons for a while? For example, if I use the exact same kind of whiskey, but one is a 12 year and one is an 18, can you tell? How about Jim Beam vs. Jack Daniels? Jim vs. Johnny? What about scotch vs. bourbon?
