I see pics of this root beer on online shopping sites as a tall 12 oz. dark brown glass bottle, but the bottle i got happens to be a stubby one (which i like). The label is very simple by catchy and probably hasn't changed much or at all since the 1960s. It's a solid brown background with an orange circle and the logo of the root beer pasted across the front. I also noted that the orange cap matched the orange circle on the label. The "Dang!" is very large and noticeable, while the "that's good" is almost an afterthought. It's almost like they were trying to capture a thought in a bottle.
I actually like this one quite a bit. Better than average even. It has a sold root beer flavor with a very slight hint of wintergreen, good carbonation, and it's sweetened with cane sugar. Kinda of a creamy finish and doesn't leave a bad aftertaste. Really can't complain. I don't think it's on the Mt. Rushmore of root beers, but it's a solid one. And because of that, i think i will be fairly generous to this root beer with my rating (spoiler, but not very much of one because my rating is just below this sentence).
My official review is that Dang! gets 7 (seven) IBCs. It's a good root beer, much better than average or mediocre and therefore deserves to be elevated above a 5 or even a 6. Well done city of Milwaukee. You've managed to give me something to say about you.
