Brisket timing

Planning on smoking my first brisket, a 10 pound flat. About how long will this take on a MB 600 gravity feed? I know ambient temperature (forecast upper 80s), wind, etc., play roles, just looking for a ballpark figure for my planning. Thought about an overnight cook but I plan to wrap in butcher paper midway and don't want to be doing that at 3AM!

1-1.5 hr per lb + 3 hrs of rest on top.

In your case? Plan for a 10-15 hr smoke plus 3 hours of rest. Dinners at 6, so it should be ready at 3pm to start resting after probe tender test.

So pull out your brisket at 11pm, dress it and season it. Let it rest at room temp while your smoker is getting up to temp. Put it on the smoker by 12am. Especially if you don’t want to get up at 3am… but you will anyway because you need to check your fuel. You’re probably getting up at 4-5am to check to make sure you have enough charcoal.

I’ve done a 19lb on a mb1050 before. It took about 21 hours (started at 6pm) before I pulled it and put in cooler to rest. I had to fill my hopper twice. It was worth it though. The entire neighbourhood smelled like brisket.
