Found this in a four pack on vacation and decided "why not". I love butterscotch, I love glass sodas, and I love cool bottle caps (this one has a nice purple twist-off).
It very much lives up to it's name, it's a butterscotch beer through and through. I really think it does a good job of giving you the butterscotch flavor without making it overly sweet. With butterscotch it's too easy to sweeten the flavor so much it starts to burn on the way down, but this doesn't do that.
It's refreshing and light, though I do think it could use a little more fizz. You know it's a good bottled soda if you see mist seeping from the neck of the bottle after you open it. The Flying Cauldron didn't have any of that.
I'd recommend going into it with homemade root beer in mind, it's very reminiscent of that.
Also, I must say, it hit even better drinking it at the beach.
