Parabola is a beer of darkness and immensity, a barrel-­aged beast that is routinely ranked as one of the top beers in the world.  This Russian imperial oatmeal stout is aged for a full year in  Heaven Hill barrels, developing flavors of rich, chewy roasted malts, charred oak and bourbony vanilla. Parabola bares its teeth with its impenetrable black hue and soaring alcohol, yet its bite remains refined with a silky, balanced finish.
