The poster campaign, which kicks off on 7 March, features photos of partially unwrapped Green and Black's chocolate accompanied by witty headlines.
Each poster also carries tasting notes and a new "Inspiring Taste" strapline. It continues a theme of "taste" for the brand, which launched a search for a new taste assistant and second cook book last year.
"This marks a very exciting stage in the Green & Black's journey to pique the interest of foodies," said MD Guillaume Brochen.
Green & Black's has proclaimed itself the world's largest organic and Fairtrade chocolate brand, following it gaining Fairtrade certification for all its block bars and beverages, effective from January in the UK and globally by the end of this year.
