In a small saucepan, bring 2 cups of the water to a boil. Add the tea bags and allow to steep for 10 minutes. Discard the tea bags. Stir in the sugar until it dissolves.
In a large container, combine the brewed tea, lemonade and orange juice concentrates, remaining water and bourbon.
Place the container in the freezer for at least 4 to 6 hours or preferably overnight until the slush is firm all the way through.
Scoop the bourbon slush into a tumbler glass, top with ginger ale and serve.
