How many kilos / pounds charcoal for a 20 hour burn?

Brisket provides ample time to stare at your drum and drink rum with your friends

I cooked a 12.5 lb. brisket last week-end in 6 hours on the UDS then 2 hours wrapped in a ice chest. Ambient temperatures were 42-46, cooking temperatures were 300-320, used 8 lbs. of Kingsford Blue.

Hope this helps.....

Don't forget...your neighbors apple trees make good cooking wood

Shoes - noted, my neighbours apple tree hangs over part of my garden....YOINK

ive got a left handed bandera with no mods and it take about 3 full bags of Kingsford for a 12 hour smoke... need to do those mods bad but its too damn cold outside

Sorry I missed a chunk of the thread UDS, but yes approx 11 hours at 275 (again might be a little quicker if you spike up or a little longer if you let the temps drop occasionally). Glad you got it worked out.

Lots of good suggestions here.

Don't forget the cardinal rule -- it's done when it's done. Suggested cooking times should be treated as "estimates." Go for "probe tender," not a particular time or internal temperature.

My Select briskets in. 12-15 lb range take 6-8 hrs at 300* but the Choice Brisket I've done of same size took 10.5 hrs because of the higher fat content....... So If running at 275* I'd wrap at 5 hrs and start probing every 45 minutes at 6 hrs.

I just did an overnight butt on Christmas Eve. Got 15 hours on a kettle at 225 with a snake burn of 10# of Stubb's. No ATC, alarms, or thermometers; just set and forget! The crazy part is that it was 8 degrees outside with a 10-15mph wind! I built a plywood shack around the cooker and woke up every 3 hours just to check. I ended up not touching anything on it all night and could have slept straight thru. Honestly, I was shocked and fully expected to use over 20# in those conditions. It's the first time I've fully enclosed my cooker, but with efficiency and consistency like that, it won't be the last!

It's amazing how much more time choice can take.
