I am planning a brisket for today Georgia and Florida game. (Go Dawgs). It 12 lb and I start last night at 9 pm planning on 16 hours cook. It at 180 IT now. I cook it between 225 and 250. It look like it going to be done before we were planning to eat around 5. I am checking hourly with the toothpick. but it if is done before hand what is the best way to keep warm. I am planning on double wrap it in heavy duty foil and let rest. How long will it stay warm or what the best way to reheat it for the game?
