Redbull

Ah yes, Redbull, the first energy drink known to man by many.  Or Coffee is the first energy drink I actually suppose.  But yes, Redbull is probably THE tastiest energy drink.  The cons of Redbull are that it's too expensive and it lacks in the vitamin department so it doesn't do too much for energy besides the caffeine content.  Redbull kind of has a citrus taste, very delicious.  Definitely try it if you haven't had it, but I am sure you have if you're reading an energy drink review blog.
