In his article “Uncharted Territory: S. Eubayanus,” Jared Spidel dives into a little known—and hard to get—yeast called Sacchormyces eubayanus. Spidel was on a mission to understand this newfound strain, so he decided to set up a homebrew competition to see how S. eubayanus works in various different styles. This brown porter recipe earned competition entrant Chris Clair the best-of-show title.
