Unobtanium is a barrel-aged English-style Old Ale that ages for six months in a bourbon barrel, soaking up all sorts of amazing whiskey character as well as hints of oak and vanilla. The name was taken from an old aerospace/engineering term for a specific material or object (often imaginary, impossible or highly improbable to obtain) needed to complete any given project. And, before you ask, we did not take the name from the elusive metal in Avatar. James Cameron reportedly named the substance as an inside joke to his fellow techie/gear-heads. Our version is much tastier, though.
