Google employees from around the world offered suggestions that went into the creation of the final product. The finished product contains chocolate malts and Belgian dark candi syrup, wattleseed from Australia, amaranth from South America, green rooibos from Africa and myrica gale from Europe. The beer is in "the style of a Belgian Dubbel."
Currently, the beer is only available at the brewery, but it could go into distribution. Check out this documentary on the project.
