 Jess says the key to managing heat on a charcoal grill is to create temperature zones. Based on how you arrange the charcoal in the bottom of your grill, you can create a super high hot zone of temperature if you kind of like stack all of the charcoal on top of each other off to the side. And then whatever area of the grill grate isn't over that or is further away from that stack of charcoal then becomes a cooler temperature zone.
