What exactly is a golden stout? I just saw a golden stout, I thought that stouts had to be dark and use roasted malts. What does a golden stout taste like? The same as a stout minus the color?
Sort of.

These stouts my also be known as "Blonde" or "White" in additional "Golden". Supposedly the idea first came about in 2007, when it was joked that Stone should brew a Golden Stout, it being a sort of oxymoron. However, it appears that now it exists. Stone Brewmaster Mitch Steele decided to create it, a light colored beer which had the flavors of a stout,


  “To achieve the qualities of a stout, we relied on our prior experience brewing with coffee to pull flavors from the beans without affecting the hue of the beer,” explains Steele. “As the beer warms and opens up, the chocolate adds another level of complexity and helps build the traditional flavors typically associated with dark beers. It’s been really fun to see a prank with questionable viability become a reality.”


While this isn't the only example, it's one of the more notorious ones that serves well to explain the idea as well as how the flavoring is achieved.
