Myron Mixon uses a lot of peach wood.
I use whatever is available locally.
NC uses hickory cause they have it.
TX uses post oak and mesquite...
Here in N. Central MD we have tons of
Wild black cherry, apple, maple, pear, peach
and oak. Hickory not so much.
So that's what I use.
Regional Q styles all burn what is nearby.
They didn't have Academy or Wally's World of Goodies
down the street to pick up a bag or 2.
I have to admit, haven't seen the bagged peach before.
I go to an orchard down the road and get all the prunings
I want for nada.
BTW, you can use non flowering fruit trees as well.
Bradford pear has a really nice flavor.
