Assuming you are talking about cooking a whole chicken in a beer can:
The perfect temperature for beer can chicken is 165 degrees Fahrenheit. This ensures that the chicken is cooked through and juicy, while also allowing the skin to get nice and crisp.
To achieve this temperature, start by preheating your grill (or oven) to 400 degrees Fahrenheit. Then, place the beer can chicken on the grill (or in the oven) and cook for 45 minutes. After 45 minutes, use a meat thermometer to check the internal temperature of the chicken. If it has reached 165 degrees Fahrenheit, it is done!
If your chicken isn't quite at 165 degrees yet, continue cooking it until it reaches that temperature. Once it's done, remove it from heat and let it rest for 5-10 minutes before carving and serving. Enjoy!
