Frequently Asked Questions
How much charcoal for a 22-inch kettle grill?
For a standard 22-inch Weber kettle at medium heat (350–400°F) for a 2-hour cook, use approximately 4–5 pounds of briquettes (about 80–100 briquettes), or about 1.5 full chimney starters.
Lump charcoal vs briquettes — how much do I need?
Lump charcoal burns hotter and faster than briquettes. You typically need about 20% less lump charcoal by weight compared to briquettes to achieve the same heat. However, lump is less consistent in size.
How long does a full chimney of charcoal last?
A full chimney of briquettes (about 80–100 pieces) provides about 45–60 minutes of direct high heat, or 1–1.5 hours at medium heat in a kettle grill. For longer cooks, add fresh charcoal or use the snake/minion method.
What is the snake method for charcoal?
The snake method arranges unlit briquettes in a C-shape around the grill, with lit coals at one end. As the fire slowly burns along the snake, you get 6–12 hours of consistent low-and-slow heat — perfect for brisket and pork shoulder.
