Bourbons can be pretty predictable. Sweet, caramel, and oak. I like the high rye bourbons because they add the extra complexity from the rye.
Now, The high rye ryes (they have to be 51% to be called "Ryes" as per Federal Law) They have a personality of their own. MGP makes juice for many companies and they have a 95/5 Rye that is quite delicious. 95% rue, 5% malted barley. You may get spearmint or tea flavors from that.
