You can run a Santa Maria grill on charcoal, hardwood, or a combination of both, and the choice changes the flavor, the cost and how much attention the fire needs — not the cooking method. The grill's crank adjusts heat by raising and lowering the grate, so your job with any fuel is to build a bed of glowing coals, not to manage vents or dials. Charcoal gives you a predictable, low-fuss fire; hardwood adds the classic live-fire flavor that Santa Maria cooking is known for but asks for more hands-on attention.
The role of fire in Santa Maria cooking
Santa Maria grilling works best over a wide, even bed of coals rather than a leaping flame. The grate sits above the firebox, and you raise or lower it to control intensity: lower for searing, higher for gentler cooking, and higher still to hold food warm. Because the grate moves instead of the air, what matters most is a consistent coal bed that you can replenish without letting it flare.
That changes how you should think about fuel. You are not lighting a fire and walking away; you are building and tending a coal bed for the length of the cook.
Cooking with charcoal
Charcoal is the easier fuel to control. Lump charcoal lights predictably, burns evenly, and produces a clean, steady coal bed with less flame management than logs. It is a good match for weeknight cooks, for cooks where you cannot watch the fire constantly, and for anyone learning the Santa Maria height system — with charcoal, heat changes come mostly from the crank rather than from the fire.
The trade-off is flavor. Charcoal adds a clean, smoky base, but it does not deliver the pronounced wood character that hardwood does. If your goal is authentic Santa Maria-style tri-tip with a noticeable oak influence, charcoal alone may taste a little neutral.
If you go the charcoal route, choose lump charcoal over briquettes when you can. Lump charcoal is made from real wood, lights faster, burns hotter and produces less ash, which suits a fire you will feed for an hour or more. Briquettes burn longer and more uniformly, which can be useful, but they add fillers and ash that a live-fire grill does not need. Light the charcoal with a chimney starter or an electric starter rather than lighter fluid — fluid can leave a flavor on food and flare when you add wood on top.
Cooking with hardwood
Hardwood — traditionally oak in Santa Maria cooking — is where the signature flavor comes from. Split logs burn into fragrant coals, and the smoke they release while they catch and settle seasons the meat in a way charcoal cannot replicate. Cooks who want that flavor accept more work: logs need to be arranged, lit, allowed to burn down to coals, and replenished through a long cook.
Not all wood is equal for this job. Seasoned, kiln-dried hardwoods burn hotter and cleaner than unseasoned wood, which smolders and coats food with harsh smoke. Big Horn sells kiln-dried oak logs for exactly this kind of fire, and oak is the traditional Santa Maria fuel. Keep the wood dry and store it off the ground so it stays that way.
Plan the wood fire in phases rather than expecting logs to behave like charcoal. Start with smaller splits or kindling to establish the bed, let the first logs burn down until they glow, then add larger pieces as the cook progresses. Wood added too late in the cook smokes more than it heats, because it has not had time to become coal; wood added too early flares under the food. Give each new piece five to ten minutes to catch and settle before you lower the grate over it.
Combining both fuels
Most experienced Santa Maria cooks do not choose one fuel — they combine them. The common pattern is to build the initial coal bed with charcoal, then add hardwood chunks or small splits as the cook goes on. Charcoal gives you a fast, reliable start; the hardwood adds flavor and extends the bed. This hybrid also makes timing easier: light the charcoal first, get the grate height dialed in, and feed wood only when you want the smoke and heat character to shift.
Start with roughly a two-to-one ratio of charcoal to wood and adjust by feel. Too much wood at once creates flare-ups and heavy smoke; too little and you lose the flavor you added the wood for. Add one or two chunks at a time near the edge of the bed rather than dumping wood into the center.
The hybrid also protects you from the classic wood-only mistake: a fire that dies mid-cook. When the charcoal base is established, the cook has a floor of heat it can always return to; the wood becomes a flavor layer on top rather than the entire system. If the wood you add flares, raise the grate, let it settle, and only lower the food back when the flames have dropped to a clean glow.
Managing fire height and heat
With a Santa Maria grill, heat control is mostly a crank question, but fuel placement still matters. Keep the coal bed wide enough to cover the cooking area — a narrow bed makes the edges of the grate useless. When the fire runs low, add fuel to the back or side of the bed so new coals ignite gradually instead of flaring directly under the food. If a flare does climb, raise the grate and let the flames settle before lowering it back.
For a long cook, plan two fuel phases: a hot phase for searing over a fresh bed, and a maintenance phase where you add fuel in small amounts to hold the temperature while thicker cuts finish.
When the fire is not behaving, read the symptoms before adding fuel. A fire that will not hold heat usually means the coal bed is too small, the fuel is damp, or too much ash has built up under the grate; fix the bed rather than cranking the grate lower. Heavy white smoke usually means fresh wood is smothering the fire or the wood is wet — let it catch at the edge of the bed and give it air. A clean, wispy blue smoke is what you want near the food; if you see thick smoke, raise the grate and wait for the fire to settle.
Fuel-handling tools make the difference between a relaxed cook and a frantic one. A long-handled shovel or scoop moves coals without leaning over the fire, a pair of heat-resistant gloves protects your hands when you adjust logs or the grate, and a metal bucket or ash can gives you somewhere safe to put spent fuel. These are simple items, but they are the ones you reach for constantly — buy them before the fancy accessories.
Choosing for your cook
| Scenario | Fuel that fits | Why |
|---|---|---|
| Quick weekday cook | Charcoal | Predictable start and steady heat with less tending |
| Authentic Santa Maria flavor | Hardwood (oak) | Wood coals and smoke deliver the classic character |
| Long cook with family around | Charcoal start + hardwood feed | Reliable base with flavor added through the cook |
| First time on the grill | Charcoal | Lets you learn the crank system without fighting the fire |
| Bigger group, longer session | Charcoal start + hardwood feed | Sustains heat and adds flavor across hours |
| Flavor-forward weekend cook | Hardwood (oak) | Classic Santa Maria character when you have time to tend it |
Big Horn's portable Santa Maria style charcoal grill is designed for exactly this adjustable-grate cooking — its official product photo shows the grate loaded with steaks, sausages and chicken over a live fire. The larger Argentine Santa Maria style grill gives you a bigger firebox for wood-fueled cooks with a crowd. The grills and griddles collection rounds out the options.
Start with the fuel that matches your time and experience level, then experiment in the direction of the flavor you want. A Santa Maria grill rewards attention, and the fuel you choose simply decides how much attention it needs.
Whichever fuel you run, end the cook the same way: let the fire burn down, spread the coals thin to cool, and remove ash once everything is cold. A clean firebox makes the next fire easier to start and keeps the grate mechanism free of buildup — the crank that looks smooth on day one stays smooth if ash does not collect around it.
