Heat your smoker to 225 degrees and add your favorite wood chips. (apple wood is a good choice if you are unsure what to use)
Place the raw bratwurst inside the smoker and let cook until the internal temperature of the brats reaches 160 degrees. This should take 1 hour and 45 minutes - 2 hours.
Serve immediately with your favorite toppings.
Notes
Store leftover brats in an airtight container in the refrigerator for up to one week.
