The night before cooking, unwrap the leg of goat and season it generously on all sides.
Place the goat leg on a wire rack over a cookie sheet and return it to the fridge, uncovered, overnight.
Preheat your Traeger grill to 225* with the super smoke feature enabled.
Remove the goat from the fridge and place a Meater probe in the thickest part.
Pair the probe to the app and set for a target temperature of 203*. Use the app to guide your temperature selection based on the meat you're using (the Meater app has a goat leg option).
Place the meat in the grill and close the lid.
Allow the goat to smoke at 225* until the internal temperature reaches about 165*. This took about 5 hours.
In a large foil pan, combine the onion, white wine, beef broth and more of the rub.
Submerge the goat leg in the braising liquid and cover the pan tightly with foil.
Return the pan to the grill and continue cooking at 275* until it reaches an internal temperature of 203*.
This could take about 3 more hours.
When the meat reaches 203* as identified by the Meater app, remove the pan from the grill and allow the steam to release from the pan.
Recover the pan and allow the meat to rest for about 20 minutes.
Using gloved hands, shred the meat off the bone, discarding any fatty or sinewy pieces.
Serve your Traeger Smoked Pulled Goat Leg like you would other pulled smoked meats-- on a sandwich bun, as a taco filling, or on a pita for a Mediterranean-inspired meal.
