I've noticed from several posters that there seems to be a small (but accepted) practice of mixing several different bourbons together. I believe the last one I read mixed wheated bourbons with ryes or maybe it was a Van Winkle. Regardless, this is not something I ever really considered. Of course I wouldn't put anyone down for their method of enjoying our favorite libation. I just wanted to see what others thought of this practice. Would it be something you would try, or are you adamantly against it, and why? Also from those who do, what some of the best/most interesting combinations you have come up with. Or even some of the worst to avoid.
