Bierlikör, or beer liqueur, is a beer-flavored liqueur, traditionally produced in the German state of Bavaria. As the term is not legally protected, individual products vary. Bierlikör can be made at home, but is also available commercially.
Bierlikör has long existed as a niche, side product for breweries. Old or unsold beer was frequently made into Bierbrand or Bierlikör, both of which have a longer shelf life. A reference book from 1900 mentions a "Bier-Essenz", which is combined with neutral grain alcohol and sugar to produce a Bier-Likör.[1] The rising popularity of craft beer in the 2010s in Germany has seen a revival of Bierlikör.[2]

Additional herbs and spices may be added as well, such as vanilla (or vanillin), cinnamon, and cloves.
A number of producers sell Bierlikör commercially:
There are a number of recipes for homemade Bierlikör, mostly using a strong beer as a base (such as Schwarzbier or Bock), which is heated up with sugar and spices, cooled, and fortified with a distilled spirit.[7]
