So here has been my limited experience with my new (used) 14.5 WSM. For multiple sessions I used KBB and using the minion method starting with about 12 pieces of charcoal with boiling water in the pan. Every time my pit set in at 250 with all vents open. I have done some full chickens, chicken pieces, and a London Broil. I also have done ribs twice and part of the reason for doing those was to learn how the WSM behaviors as the time progressed. What I learned from those test runs was my WSM stays very stable at 250 using KBB for 6 hours then in the sixth hour the temps started to drop both times I took it that far. If I wanted to keep the temps up I would have had to add fuel toward the end of that firth hour mark. After reading a good bit of research I decided I wanted to try Weber charcoal for my first pork shoulder, the longest cook to this point. I order three bags online, and last Saturday night I went for it. The Weber charcoal is much larger, so I started the minion with like 8 pieces of charcoal. Boiling water in the water pan, and it quickly climbed into the 200's and I shut all three dampers down most the way. I left all the dampers mostly closed the whole cook. I added about 20 unlit pieces of charcoal about 5 hours into the cook (1 am when I went to bed, as a pre-measure to help with the goal of getting some sleep) then as the cook progressed the temps climbed and settled between 275 and 285. I have not been able to do that yet with KBB. The shoulder was done at 9 hours and I closed all the dampers. Later when I went to clean up the smoker I still had charcoal left. I think I could have made it the 9 hours on my original fuel, but it would have been close. The ash was not that bad. Now I could not find the Weber Charcoal local and had to order it online from ABT and it was pricey, but in my mind worth it. So like I said originally, for anything 5 hours or less, I will use the KBB and for my longer cooks I will use the Weber.
