If you like to cook meat at a low temperature between 225°F and 250°F (107°C and 121°C) if you do not have a pellet grill, you have to learn how to keep a charcoal grill at 225 and maintain this temperature.
When I started smoking at low temperatures I had a lot of problems keeping my temperature under control.
This caused several times that my meat was not that tasty and either dry or even burned on the outside. I wrote a post on how to use the air vents on a charcoal grill and this is basically what I also do to keep my grill at 225°F (107°C).
There are a few steps that you have to take to keep your temperature consistent.
- Use the same amount of charcoal
- Use a 2-temperature zone setup.
- control the airflow.
By using the same amount of charcoal you start with you know basically what your start temperature will be. After that, you can use the Minion or Snake method I described here to keep your grill at 225°F (107°C).
The use of the 2-zone setup is not always possible if you have a really small grill, but in most cases, you can use a Weber charcoal basket and achieve this setup.
These two things are the first important step to keep your temperature between 225°F and 250°F (107°C and 121°C). The most important step is to use your air vents the right way and this might take some testing.
Many sites tell you to leave your top vent open and regulate the temperature with your bottom vent. This will work well in many cases and on many grills, but not on my grill.
I had to close the top vent to about 50% to even be able to lower the temperature and keep it consistent. With the top vent open, I lost all my temperature and was burning charcoal like crazy.
All together there is no possible answer to this question that will work for every grill and every situation.
One other thing I always use is my Weber Charcoal starter to make sure my charcoal is lit all the way. By using the same amount of charcoal and this chimney starter I am almost certain that I start with the right temperature.
One difference is that you do not burn the coals all the way till they are grey like suggested for grilling.
You lose too many coals at the bottom. I pour my coals into the grill when the flames are licking at the top briquettes.

The best charcoal to use for cooking on low and slow around 225°G (107°C) is briquettes. The reason is that they are uniform in shape and this makes them all burn the same way compared to lump charcoal.
I like to cook low and slow for the simple reason that it makes the meat very tender. Besides that, it offers another way of using your grill and in this way expands the options you have to use it.
This is a great tip on how to use a charcoal smoker grill and if you use it this way your temperature will stay steady.
