Whether the meat does or does not have a smoke ring is not part of the judging criteria in BBQ comps.I find it hard to believe, running at 375 for the entire cook.........It just don't add up to me. And I'm not one of those ultra low heat cooks either, 275-300* is usually where you will see my smokers running, higher on chicken, and when finishing the ribs.....but doing a Butt at 375, its hard to imagine it having much of a smoke ring, and not getting too crispy on the outside.anything much more than 300* starts to create a barrier crust that will not allow any more smoke penetration.......
I think its a regional thing, before joining this forum I was limited in my exposure to the BBQ culture with what I grew up with, and what we here judge as the quality of true Q. What we may turn our nose's up at , others may consider to be the "bomb". The same is true with just about all cuisine, right? Whats true pizza, Ny or Chicago? BBQ is even more regional, Texas style, Memphis style, Carolina style, and on and on.Whether the meat does or does not have a smoke ring is not part of the judging criteria in BBQ comps.
I do not know where you came up with your statement on a crust forming at high temps that does not allow smoke penetration, I always get plenty of smoke flavor on my turkey burgers and they are liberally coated with rub and seared over very hot lump and grilled indirect at 450°-500° and the maple I use for smoke flavor always does its job.
Myron Mixon's butts do not get too crispy because his smokers have a large capacity water pan, the steam creates a moist environment.
If you have a Netflix account I believe they still have the first season of BBQ Pitmasters on there, you can watch it for yourself, Episode 1 believe
Keep your wood dry....Does soaking the wood (in water or apple juice, etc) for any period of time prior to your cook have any effect...
