Why do people use foil?
I would say that:
1) smoke ring stops forming after the meat has reached 140-150F internal temp;
2) smoke absorbtion will NOT stop until the end of the cook. So it could be oversmoked.
All good reasons to foil, Chris. One drawback I've found is that as the meat braises, the smoke flavor seems to be washed away somewhat. Another drawback (or benefit depending on how you look at it) is that the bark becomes softer. I foil my briskets to reduce cooking time (hot and fast method) and they come out great, but I prefer pork butts with a hard, crisp bark so I almost never foil them unless time requires it.You can use foil to control the color of the meat. If you're using a rub with lots of sugar in it and you don't want your ribs or butt or brisket to look like a meteorite, you can apply smoke for a few hours, get some nice color on the meat, and then wrap with foil and cook until tender. This is common in competition barbecue.
You can use foil to accelerate the cooking process. If you don't want to babysit a brisket overnight, you can take it to 170*F then wrap it in foil and cook it at higher temp and it will be done much sooner, e.g. Brisket - Smoked & Oven Finished.
You can use foil to add flavor. A common competition technique is to wrap ribs or pork butt in foil and add flavorful liquids, honey, agave nectar, etc. to enhance flavor toward the end of cooking, e.g. Pork Butt - SYD Injection.
