Food Recipes, Smoking, etc...

Bbq brethren forum. I started with a UDS ( ugly drum smoker) and graduated to a big green egg. I still use and love the drum for pork butts. I do one for pulled pork sammies and do a second butt that after pulling, I put in small portions and freeze. Then I can pull a package out and add it to some beans for lunch, make a sandwich for work etc.
I am planning on building a UDS some time down the road. Just wondering...guessing you vacuum seal the frozen portions? If so how do you reheat? Have been told that placing the still sealed package in a pot of heated water, after it has thawed, will result in the same flavors that you had right after it was smoked.
Sorry if the above is hard to understand.
