One of the most common questions we get: "How much charcoal do I actually need?" It's a fair question. Use too little and you're fighting for heat all cook. Use too much and you're wasting fuel. Here's the definitive breakdown for every type of cook.
The Quick Reference
| Cook Type | Firebull Amount | Cook Time | Target Temp |
|---|---|---|---|
| Quick burgers/hot dogs | 1/2 chimney (~3 lbs) | 20–30 min | 400–500°F |
| Steaks (sear) | 1 full chimney (~5 lbs) | 15–20 min | 600–700°F+ |
| Chicken pieces | 3/4 chimney (~4 lbs) | 45–60 min | 375–425°F |
| Whole chicken | 1 full chimney + indirect | 1.5–2 hrs | 325–375°F |
| Ribs (3-2-1 method) | 1 full chimney + 1 lb/hr | 5–6 hrs | 225–250°F |
| Pork shoulder | 1 full chimney + 1 lb/hr | 8–12 hrs | 225–250°F |
| Brisket (full packer) | 1 full chimney + 1 lb/hr | 12–16 hrs | 225–250°F |
The Chimney Method
The chimney starter is your best friend for consistent, measured charcoal use. A standard chimney starter holds about 5–6 lbs of Firebull lump charcoal when full. This is your baseline unit of measurement. For most cooks, you'll start with a full chimney of lit charcoal and add unlit pieces as needed to maintain temperature.
Pitmaster Tip
Pro Tip: For long cooks, use the "minion method" — start with a full bed of unlit Firebull in your smoker, then pour a half chimney of lit coals on top. The lit coals slowly ignite the unlit ones, giving you 6–8 hours of steady heat without adding more charcoal.
For Short, Hot Cooks
Steaks, burgers, chops — anything under 30 minutes. Use a full chimney of Firebull, concentrate the coals in the center or on one side, and cook hot and fast. You'll have plenty of heat for 4–6 steaks or 8–10 burgers. The coals will still be going strong after you're done.
For Medium Cooks
Chicken, fish, vegetables — 45 minutes to 2 hours. Start with 3/4 to 1 full chimney and set up a two-zone fire. You'll have enough heat for the entire cook without adding more charcoal. Firebull's long burn time means you won't be scrambling to add fuel mid-cook.
For Long Smokes
Ribs, pork shoulder, brisket — anything over 4 hours. This is where Firebull really shines. Start with a full chimney of lit coals on top of a bed of unlit lump. Plan on adding about 1 lb of unlit Firebull every hour to maintain your target temperature. For a 12-hour brisket, you'll use roughly 12–15 lbs total — most of a 20 LB bag.
Storing Leftover Charcoal
After your cook, close all vents completely to extinguish the remaining charcoal. Once cool, the unburned pieces can be reused for your next cook. Firebull lump charcoal relights easily — just add it to your next chimney load. Store unused charcoal in a dry place, ideally in the original bag sealed with a clip.
- Close all vents after cooking to save unburned charcoal
- Relight leftover pieces in your next chimney load
- Keep charcoal dry — moisture ruins it
- A 20 LB bag of Firebull = 3–4 standard cooks or 1 full brisket smoke
