How Many Charcoal Briquettes to Use for 250 Degrees?

Charcoal grills are notorious for controlling heat. Out of all grill types, charcoal grills are the most difficult in this area. Every owner of a gas or an infrared grill will tell you how easy it is to control heat: you just turn the temperature knob at the right angle.

To figure out how many charcoal briquettes to use for 250 degrees Fahrenheit in your grill is vital as it helps in utilizing your barbecue the best way it was designed to be used and results in culinary creations that are juicy and delicious.

The amount of charcoal briquettes required depends on the type of meal you are cooking, and the level of heat you need on your grill.

Since 250°F is a lower heat temperature, you need to arrange and spread ignited coals in the tinny layer across the large area of the chimney for the heat to dissipate faster. Take a look at what you need to consider.

Temperature Test

How Do I Measure the Temperature of My Grill?

Temperature is precisely measured with the thermometer. Some grills have them built-into the lid.

You can also use your hand to determine how hot your grill is if you don’t have a thermometer.

Roughly you can approximate the temperature by holding the palm of your hand at a distance of 5-6 inches above your grill grate and withdraw it after some time.

The period in which you maintain your palm above the grill determines how hot is your grill.

At a low heat temperature of 250 degrees, you can only hold your hand over the grill comfortably for around 5 seconds.

I admit, it’s not 100% accurate but it’s still better than just winging it.

Are Grill Thermometers Accurate?

Most dome thermometers are the cheapest ones the manufacturers can get their hands on (you can get them as well for around $10 on Amazon or eBay) and are inaccurate because the temperature is averaged over the length of the stem. Some are more accurate, while others are less. This is especially true for cheaper charcoal grills.

Another issue dome thermometers present is how they measure the temperature. The thermometer checks the temperature of its stem. Why is this an issue, you ask? The problem here is that the stem is located at the other end of the heat source, i.e. burning charcoal.

It’s way hotter below the grates than above them.

That’s why some grillers recommend using thermometer probes and measuring the temperature an inch or two above the grates.

How Many Charcoal Briquettes to Use for 250 Degrees?

To reach 250 degrees, you don’t actually need many briquettes as this is a very low grilling temperature.

There are many other factors that impact the temperature of a grill and not just the amount of briquettes, like the ambient temperature, the wind, how you place the charcoal, etc.

The last one (how to place the charcoal in the grill) is very important. That’s why you need to familiarize yourself with the charcoal placement methods below.

How to Arrange Charcoal Briquettes to Reach the Optimal Temperature of 250°F

How you fill and spread your briquettes will have an impact on the amount of heat your grill makes. Here are some primary ways to spread your briquettes:

Two zone fire

This is the most common configuration that involves spreading briquettes on either of the sides of your grill or both.

It’s perfect for low-temperature cooking and smoking. It results in low heat temperature, and it requires a whole chimney to start with 100 briquettes and extra coals.


It is a very slow method of cooking that uses indirect heat and smoke to cook food. Chipped wood and hardwood chunks are soaked in water to produce the smoky aroma you know and love.

You can smoke only at lower temperatures, i.e. while barbecuing. Smoking is possible while grilling too, but the smoking results are negligible.

Barbecuing and grilling are not the same, though. Take a look at this grilling guide to find out more.

The Snake

What Is the Snake Method of Grilling?

Smoke wood and unlit briquettes are spread circularly around the edges of the grill. On one end of the snake, you add a few lit briquettes to begin the process, which burns slowly for hours. It results in low heat and requires 100 unlit charcoal briquettes, 6-8 briquettes to start the snake, and additional briquettes for later.

The Minion Method

This method is the go-to choice for smokers and barbecue lovers. With this charcoal placement method, you’ll reach and easily maintain the magic 250°F without the need to add fuel.

The concept is simple: place hot lit briquettes on top of cold ones and use the vents at the bottom of the grill to regulate airflow.

You can cook low and slow for an extended period of time, up to 18 hours.

According to the creator of this method, Jim Minion, you need to light up 20-60 briquettes, depending on the weather.

Depending on how long you want to cook at 250 degrees, you can add the same number of unlit briquettes as lit to the grill or much, much more.

There are many variations of this method, and here’s the most common one:

Regardless of how you attain a temperature of 250 degrees, the number of briquettes to use will have to be adjusted for particular situations. Consider these next factors:


It causes the briquettes to burn faster and hotter since wind adds oxygen to the fire and blows away heat from the grill resulting in adding more briquettes.

Therefore, you may need a wind block or create a shield with rocks or aluminum foil around your grill when cooking in windy conditions to reduce the negative impact of the wind.

Ground Temperature and Moisture

When you are grilling near the ground, keep in mind, the moist ground absorbs heat and can extinguish your briquettes hence the need for more.

You may use a disposable aluminum pan or a cookie sheet as a barrier between the charcoal and the moist ground to provide a dry surface for your briquettes.

Altitude and Humidity

At higher altitude, the air is thinner hence the need for more briquettes while cooking. Very high humidity causes issues when you fire up the charcoal. Both factors will result in using more charcoal to reach and maintain the wanted temperature.

You may use a chimney starter to light your charcoal briquette quickly.

Air Temperature and Sunlight

Cold air temperatures and higher humidity levels rob heat from your grill, while too much direct sunlight will make a black cast iron grill heat up quickly.

Direct sunlight and warm temperatures will create conditions that require fewer briquettes for your cooking. You may need to cook under a shade to protect yourself from direct sunlight.

Aluminum and Cast Iron

The material your grill is made of makes a subtle difference in reaching and maintaining the right temperature.

Aluminum grills heat up quickly, unlike cast iron grills which heat up slowly but retain heat longer.

Now You Know How Many Charcoal Briquettes to Use for 250 Degrees

Some factors will influence the number of charcoal briquettes to burn. In windy conditions, briquettes will burn faster hence the need to add more briquettes earlier when cooking for more extended periods.

The moist and warm ground will result in more heat absorption from your grill so you will need to anticipate adding more briquettes. The same applies to a higher altitude and high humidity.

Direct sunlight is another factor that impacts the briquette requirement. Too much direct sunlight and your grill get hotter faster.

The quality of your grill is vital; aluminum grills are better heat conductors than stainless steel and cast iron ones.

How often do you grill at this temperature?
