The brewery sells refillable 1/2 gallon glass jugs with a twisty cap. It has the Moab Brewery logo printed across the front, a cross between tradional Native American rock art that can be found around Moab and local, touristy type stuff that draws people to come to Moab in the first place. We borrowed a jug and filled it up for $5, which wasn't bad an plenty enough to serve to my wife and me and about six of my friends.
The taste consensus was pretty universal... this stuff isn't very impressive. It reminded me a lot of Shasta Root Beer. There wasn't much flavor, moderate carbonation, and it didn't really taste like anything. Big Bryon aka Papa Walston, a Moab resident for several decades, informed us that the root beer from Moab Brewery has it's highs and lows. Some batches are really good and some aren't very impressive. Well unfortunately, we caught the root beer on a bad weekend.
My official review is that Moab Brewery Root Beer gets 3 (three) IBCs. On the recommendation of Big Bryon, i would be willing to give this root beer another shot (also because i have a fondness for Moab and it kinda pains me a little to rank the root beer brewed there so low). But as of right now, i would say for sure go eat at the Moab Brewery, but try something other than the root beer. It just wasn't cutting it this time.
