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).
Place the brisket on the Traeger, fat cap up and Smoke for 3 hours. After 3 hours double wrap the brisket on foil and turn the temperature up to 275 for 4 more hours. After 4 hours, unwrap the brisket and place it unwrapped on the grill for 30 more minutes.
