Brooklyn Oktoberfest is always an American example of the style that I look forward too every season. It poured a dark copper that had caramel and roasted malts on the nose. The taste was heavier on the roasted malts rather than the sweet caramel malts that are more common in the German versions. As it warmed the sweeter caramel flavors came through, but the roasted malts were dominant. Brooklyn makes great beers and their Oktoberfest is a good American version of the style.
