Dan’s Märzen

Dan Gordon, co-founder of Gordon Biersch Brewing Co., attended a brewing engineering program in Weihenstephan, Germany. It was during this grueling and demanding curriculum that Dan learned the science and art of the Reinheitsgebot, the 1516 German beer purity law.

In Gordon’s article, “Lager Brewing the German Way” featured in 2011 November/December issue of Zymurgy magazine, he shares some of the takeaways from his brewing education. He also shares some recipes from Gordon Biersch’s regular lineup , including a Märzen. Check it out below and perfect your German brewing techniques. Prosit!
