From the brewery:

Following our Weiherer Zwickerla Hell, the dark version is now also available – amber-colored, unfiltered, with a firm, creamy head. Roland Kundmüller brewed it exclusively with select ingredients from 100% organic farming. The Weiherer Zwickerla Dunkel is a beer for everyone who likes it naturally cloudy, malty, and easy to drink – a characterful Franconian dark beer.
