This is one reason that bottled tea that you buy at a store is not as healthy as freshly brewed iced tea. http://www.npr.org/blogs/health/2010/08/... I keep my sweet iced tea in the refrigerator enclosed in a lidded container for at least the third day. It still has its taste and smell! Try it! Another tip that I just recently discovered is to make ice cubes with the tea instead of water.
Dissolve salt, and sugar in water add ice, then let it cool. Place the brisket in the brine and cover, leave it brine in the refrigerator overnight. When ready to cook, remove the brisket from the brine and pat it dry with a paper towel. Sprinkle evenly with Traeger Beef Rub. Start the Traeger grill on smoke with the lid open until the fire is established (4 to 5 minutes).
Absolute, bar none, best way to reheat brisket is to drop the vac sealed bags of meat into boiling water for about 30 minutes or so. This allows the meat to steam in it's own juices and is typically better than it was when I was freshly slicing. have had good luck reheating pre-sliced brisket in the microwave by laying a few slices at a time into tight fitting pyrex microwave-ware, and spraying the slices with an apple juice and bourbon spray.
