How long to smoke brisket at 275? (Explained)

How long to smoke brisket at 275

If you’re wondering how long to smoke a brisket at about 275°F, you have come to the right place. 

On average, any brisket that is smoked at around that temperature range will cook through at a rate of about 1 1/2 pounds to 2 pounds per hour of cook time. This is towards the upper end of the low and slow method, and approaching the hot and fast temperature range.


Why you should smoke a brisket at 275

One of the reasons why you should consider smoking a brisket at about 275°F, is because it will get your cooks done a lot quicker. As you start to cook brisket at a rate of about 1 1/2 to 2 pounds per hour, you are effectively cutting the overall cooking time in half compared to smoking one at low and slow temperatures. 

Not only that, the results are very similar, if not even better than the results that you would get smoking low and slow to begin with. 

In addition to very quick smoking times, you also get a really good bark at overall crispiness on your BBQ, which is something you will not get otherwise smoking low and slow at 225°F. 

The only drawback I would say to cooking hot and fast, is that you may use slightly more fuel in the process, but it is well worth it because you can always get more fuel and you can’t get your time back!

So, I always lean on the side of cooking really hot and fast for all of my barbecue and especially brisket, in order to give my time back to myself.


Amount of fuel used in the process

It really depends on what type of smoker you have to begin with. On average though, expect to take a weber chimney starter and fill it all the way up to the top with lit charcoal. Make sure to light it thoroughly and until you see orange flames shooting out the top.

That’s about maybe a quarter bag of charcoal that you heat up and then pour into your firebox for whatever smoker you have. 

Then, going forward, you’ll want to only use wood logs or chunks depending on the size and availability of your firebox itself. The wood logs or chunks will then be used to sustain your fire and also get that rich smoke flavor for your brisket. 

To get the fire started and up to the right temperature around 275°F, consider using maybe a handful of 12 inch logs to put on top of the already lit charcoal. So throughout the cook, you can expect to at least use a quarter bag of charcoal as well as about five or so 12 inch wood logs. 

It honestly really depends, but that should be a good estimate to follow.


Average cook Time per pound at 275

As mentioned earlier, there is certainly an average cook time that you can expect to experience when you smoke your brisket at around 275°F. That cooking average or ratio is about 1 1/2 pounds per hour. 

As you start to slightly cook it even past 275°F, that rate then goes up to around 2 pounds per hour of cook time. You’re effectively be cutting the overall cook time in half and is a great way to save time while making awesome barbecue.

Now that we know they average cook time per pound, let’s take a quick look at how that correlates into different weights of brisket smoked at 275°F.


How long to smoke a 10 lb brisket at 275

If you decide to smoke a 10 pound brisket at around 275°F, you can certainly expect around a 5 to 6 hour cook time in total. Don’t forget to plan ahead though, and budget another hour or 2 to that temperature range in order to properly season and prepare the smoker to get up to that temp.


How long to smoke a 6 pound brisket at 275

If you’re wondering how long to smoke your 6 pound brisket at 275°F, then you should be budgeting about 3 to 4 hours of total cook time. That is a great estimate and will certainly render down a lot of the collagen throughout the BBQ itself. 

What you want to do as you cook it, is to just let it come up to an internal temperature of around 200°F or until you can slide a toothpick inside of it with no resistance whatsoever.


How long to smoke a 13 lb brisket at 275

Smoking a 13 pound brisket at 275°F can be done very quickly, in roughly 7 to 8 hours. That’s assuming of course that you are consistently smoking it at 275°F. You’ll want to maintain these consistent temperatures, otherwise it may take a little longer if you let the ambient temperature go down somewhat. 

If it does go down, then it’s all good because all you have to do is open your vents in the firebox so you let more oxygen in and help it ignite all the wood you already have, for hotter temperatures.


How long to smoke a 14 pound brisket at 275

Smoking a 14 pound brisket at 275°F can be done by calculating 1 1/2 pounds per hour of total cook time. That means that you should expect it roughly a 7 to 8 hour total cook time for your packer brisket. 

This is an excellent compromise, considering it would more than likely take twice as long if you were to smoke it at 225°F.


How long to smoke a 15 pound brisket at 275

Likewise, smoking a 15 pound packer brisket at 275°F would render the brisket complete at around the 8 to 9 hour mark. That’s slightly longer than 2 pounds per hour, but it’s also still a great alternative to low and slow cooking.


How long to smoke a 12 lb brisket at 275

If you’re in the market for smoking a 12 pound brisket for a period of time at around 275°F, make sure to bring plenty of fuel and know that it should take roughly 6 to 7 hours or so of total cook time. 

This is a fantastic way to smoke any type of barbecue and in particular, a brisket.


Final thoughts

Smoking at hotter temperatures is a great way to get BBQ done in about half the time it would take to smoke the same barbecue at low and slow temperatures. 

Your results are very similar and in a lot of cases, even better than smoking at those low temperatures. Not only that, but for various weights of brisket, you can certainly expect about 1 1/2 to 2 pounds per hour of cook time considering you are smoking them at 275°F.
