Pretty much Root Beer.  Nothing really stands out about it, it tastes like root beer should.  That said, it's good, not bad at all.  No weird after-taste, no "shutter" moments while drinking it.  I actually put the whole 2 ltr. bottle down in a couple days.  I, uhhh, didn't want it to go flat.  Pretty much the 1990 Ford Taurus of root beers. Not the best, but it'll fill the void.
