The broadcaster has released a Chardonnay, a red blend and a Cabernet Sauvignon via a partnership with Vintage Wine Estates.
Winemaker Bob Cabral said: “I’m a huge Game of Thrones fan, and these wines capture the complexity of the drama. But the wines also have great pedigree. We source grapes from premier vineyard sites and use the finest winemaking techniques to create wines of incredible richness and texture.”
The merchandise will carry banners and sigils from the noble houses from the show, including House Lannister’s golden lion, House Targaryen’s three-headed dragon and House Stark’s dire wolf.
The products will be available online from 20 March at a dedicated microsite.
It comes after HBO promoted the show's return live-streaming the torching of a massive ice block concealed the all-important air date.
