re: Smoking a brisket in electric smoker.

Never did one of a electric smoker but last one I did I smoked unwrapped for 12 at 225

You want to pull it off when you get the internal temp to the right temperature. I think brisket is like 180 but a simple google search will tell you. If you get it above that temp for to long it will start to dry out

ETA: I should have read Tigerpaw's response first. He pretty much covered it
