In many ways Düsseldorf altbier is the essence of a hybrid beer. The term “alt” refers to an old German style of brewing using ale yeasts, before bottom fermenting yeasts were widely available. Fermentation temperatures are kept on the cooler end of the ale spectrum, creating many of the smooth characteristics found in lagers but with an ale yeast.
The medium bodied ale showcases the richness of specialty malts while allowing for noticeable bitterness to make an appearance. Altbier is a great style to session for both malt and hop heads alike.
This recipe comes from the July/August 2009 issue of Zymurgy magazine.
