Check out Yazoo in their original brewery (the old Marathon Motor Works building) before they move to their new facility in the Gulch. Go fill your growler with one of the many handcrafted brews for the weekend or take a tour of the brewery (only on Saturdays though). Check the hours before you go as they are limited.
