"After decades of pondering, scientists have found the secret to the creation of lager. An elusive species of yeast isolated in the forests of Argentina was key to the invention of the crisp-tasting German beer (http://www.latimes.com/news/science/la-sci-beer-yeast-20110823,0,5421077.story?track=rss).
