The latest Game of Thrones beer is called Valar Morghulis, following the results of Facebook poll.
The poll, taken in December 2013, saw fans choose the name and style of the new beer.
In the world of Westeros, Valar Morghulis means 'all men must die', and the chosen style is an Abbey Dubbel, represented by the two-headed coin set to grace the labels.
Valar Morghulis, the latest result of a collaboration between HBO and Brewery Ommegang, will be available at retail in autumn of this year.
The new beer is brewed with pilsner and other specialty malts and hopped with Apollo and Hallertau Spalt Select hops. The hue is deep amber-brown with a 'persistent, creamy, off-white head'. Aromas include caramel, toffee, ripe fruit, banana and slightly burnt sugar.
"The fan response to the beers has been so incredibly positive that we thought it would be a fun reward to ask them to play an active role in selecting the fourth beer," said Bill Wetmore, director of marketing for Brewery Ommegang.
"It's not uncommon to hear 'valar brewghulis' spoken in the halls of the brewhouse, so we were secretly hoping that Valar Morghulis would be the winner. Our brewers are also excited to brew a Dubbel, a classic Belgian beer style, and have some great ideas to make this release extra special."
Valar Morghulis follows the release of Iron Throne Blonde Ale, Take the Black Stout, and Fire and Blood Red Ale in the Game of Thrones series by Brewery Ommegang.
The limited runs of Iron Throne and Take the Black sold out in a few weeks, while Fire and Blood Red Ale is selling out quickly despite being brewed at nearly double the volume of the first two beers.
"The fan base for Game of Thrones keeps growing larger as each new season debuts, and the popularity of the beers is growing right along with the show," said Josh Goodstadt, vice president of HBO Global Licensing.
"For this fourth beer, we found the perfect opportunity to give those diehard fans the power to choose what beer they wanted to drink, and we can't wait to share this special brew with them this fall."
Mike McManus, Ommegang innovation manager, added: "The Dubbel is one of the most recognised beer styles in Belgium and this is a very tasty version of that style.
"Valar Morghulis is a complex beer, much like the stories surrounding the phrase."
