I've been seeing billboards like this around the Metro area for the last 2 months or so:
My wife and I were at the liquor store a few nights ago, and we saw a 6-pack, so we picked it up so I could try it.
If you're wondering, YES it's "hard" root beer. It's 5.5% alcohol.
Brand: Best Damn Root Beer.
Origin: St. Louis, MO.
Purchase Place: Marshall Liquors, St. Paul, MN.
Sweetener: Nothing? I'm unsure on this. (Beer is labeled much differently than soda, and everyone online is mentioning they can't find an ingredients list for this.)
Review: It smelled good. The first sip had GOOD (classic) root beer flavor on my tongue. But then the yeastiness of the beer took over, and it ended with not a great flavor. There was a nice amount of vanilla flavor (and on the can it mentions that it's "ale aged on vanilla beans"), but that didn't make up for much. It was an odd flavor combo of root beer and beer that I didn't care for at all. The beer added a strange "bite" to the root beer.
I'm not a big beer fan, so that may be why I was less interested in this. But even on Beer Advocate, it's not getting good reviews and is currently ranked "poor" at 68 out of 100. One reviewer said "it tasted like someone took a cheap light beer and squirted some of that artificial "rootbeer-barrel candy" flavoring into it."
My wife mentioned it could make a good root beer float, so I may have to try that with some of the remaining 5 cans. The Best Damn Root Beer website has some recipes on it, so we might have to give a few of those a try. I'll update if/when I do. But for the time being, this score is just based on the Best Damn Root Beer by itself.
Score: 2.5 out of 10.
