Last year, one Saturday, we did a brisket test and cooked 2 16 lb briskets. After we tasted, learned, split up the briskets and everyone left my wife and I looked at a pile of sliced brisket left over. I put some in zip lock bags and I vacuum sealed some – tossed it all in the fridge. I also strained - separated the drippings and put that in plastic containers. By Tuesday we still had a bunch left over so I took it to work with a crock pot – I tossed the slices and the drippings at 7:30 and let it warm up. There are 8 people in my section and by 10:00 the brisket was gone.
For 3 day old brisket it tasted great and still had the smoke flavor. Reheating it in a crock pot with its drippings worked out well and it was very moist.
