How to Brew Double Bock Beer

A doppelbockĀ  is a German style beer that is fermented and conditioned at low temperatures. It is a smooth and warming classic German lager with an intense maltiness. Its colour changes from gold to dark brown, depending upon the period of fermentation. The darker versions of this lager may have a slight roasty aroma due to the reactions between the malt, the boil, and aging. The minimum lagering time when brewing double bock beer is 3 to 8 weeks, but some bocks require longer lagering times as well. Since it requires low temperatures for fermentation, dopplebock is usually brewed in winters.
