What is "arnbitter"

Arnbitter is a Danish bitters produced and distributed by the Copenhagen based company Just Drinks. The drink can be traced back to the 1950s and is sold under the slogan "Hverken ny, trendy eller importeret" (English: Neither new, trendy nor imported). The recipe is secret but includes ginger, cloves, safran og licorice root. Arnbitter is mixed in large 2,500 litre copper tanks where it is stored for 3 months before it is ready.
