Kaiser Ur-Trunk is a dry quaffer with a hint of milk chocolate and just might be the best Dunkles in the Bamberg area.
Becher-Bräu/Mann's Bräu Dunkel is a chestnut beauty with hops up front and chocolate malt in the balance. The finish is semi-dry and bittersweet.
Ebensfelder Adam Riese Urtrunk is a gorgeous dark brew with a great balanced palate and some hops in the nose.
The Klosterbrauerei Bonifatius Dunkel is an excellent example of the style with hints of chocolate in the malty mix.
