König Ludwig Weissbier Alkoholfrei is the alcohol-free counterpart to the brewery's full-strength hefeweizen, dealcoholised from the original rather than built as a separate recipe. The beer is produced at Schloss Kaltenberg, a working castle brewery outside Munich that has been in Wittelsbach royal family ownership since the 13th century. The dynasty held the Bavarian weissbier brewing monopoly from 1602, a heritage that places König Ludwig among the oldest continuous hefeweizen traditions in Germany.
