Wow. I seriously have recently realized the same thing (especially with the minion method). That is, that the blue bag Kingsford (I get this from Lowes usually) just imparts too much a charcoal taste to my liking and produces a gross smelling/tasting overpowering smoke. I though it was just me. My girlfriend even said: "Why do you keep buying Kingsford, you always complain about it."
When I grill and get the coals white-hot, I don't have any problem, but on my WSM, I don't plan on using the blue bag, or charcoal, again anytime soon.
I just switched to Roal Oak lump (not a preference, just what was available close by) and made a very tasty mess of ribs. No charcoal taste, no terrible smelling smoke--just good, clean tasting meat. But I will admit that since I was tired of the off-taste imparted by charcoal, I did let the lump get white-hot before closing up my smoker, having given up on the minion method after my bad experience with minion and Kingsford.
