Wondering what temperature brisket is done? If you’ve been told it’s 203F, that’s only part of the story. Brisket doesn’t finish at one universal temperature, and elevation plays a role.
As elevation increases, the boiling point of water decreases. That changes how moisture behaves inside the meat, which often means brisket becomes tender at a lower internal temperature when cooked at higher altitudes.

PRO TIP: For a moist brisket every time, follow all of the steps in my no-fail brisket recipe.
Water boils at 212F at sea level, but as you go higher, that number drops. And since brisket breaks down best when it reaches the boiling point internally, you need to adjust your target brisket temperature to match your location.
So what temperature is brisket done where you live? At 1,500 feet above sea level, water boils around 209F. At 5,000 feet, it’s closer to 203F. That’s why brisket cooked at altitude often finishes tender at a lower internal temperature than brisket cooked near sea level.
To help you dial in realistic temperature expectations, use my brisket done temp calculator. Enter your elevation to see how altitude affects internal temperature benchmarks.
Don’t guess when your brisket is done. Know it. And cook it like a pro, no matter your elevation.

How to measure the internal temperature of brisket
I use a couple of different reliable tools to measure the internal temperature of brisket.
If you want to monitor the brisket as it cooks to see exactly when it reaches your ideal temp, use a leave in thermometer. I recommend any of the following.
Insert the probe into the center part of the brisket to get the best reading.
Thermoworks RFX
Thermoworks Square DOT
Thermoworks Signals
Thermoworks Smoke X
In addition to that, I double check the temperature by using a Thermapen ONE. I insert the probe in various spots. I’m looking for the temperature reading, but I also use it to feel for tenderness.
The probe should go in smooth like butter.
Christie’s Pitmaster Take
I love tools like this because they set realistic expectations, especially for cooks at higher elevations. But no calculator can tell you exactly when your brisket is done.
Use elevation and temperature as guides, not rules. The real finish line is still probe tender. When the probe slides in with little to no resistance, that’s when the brisket is ready, no matter what the number says.
Think of this calculator as helping you aim smarter, then let the meat give you the final answer.

My Go-To Brisket Rub for Building Flavor and Bark
I use Girls Can Grill Brisket Rub on all of my briskets. This blend layers salt, pepper, garlic and savory spices to highlight the natural beef flavor while helping the bark develop evenly.
Great info on brisket elevation!
When cooking brisket hot and fast…..in a reverse flow off set wood burner. I have found 300° is my ideal temp to run at and yes cooking flat only takes about 5 – 5 1/2 hrs.
My issue seems to come in at my rest time. At a comp earlier this month I started my flat at 330 am and I pulled it off when it reached 203 at around 9am and vented it til it dropped down to 150 then put in cambro until 130pm to slice for 2pm turn in. Seemed moist when sliced but got comments that it was dry.
So it had a nice long rest. What am I missing? Or what should I change? I did inject it with H.R beef, worcestshire, beef stock and beef tallow.
