In a stroke of marketing genius, Marmite once collaborated with another titan of taste: Guinness. The result was a limited-edition spread that used the yeast from the famous Irish stout in its recipe, creating a richer, deeper, and arguably even more divisive flavour.
Launched with the tagline "My Goodness, My Marmite!", a play on the classic Guinness slogan, the collaboration was a hit with collectors and adventurous eaters alike. The jars themselves became collector's items, featuring the iconic black and gold branding of the stout.
While it is no longer available, the memory of Guinness Marmite lives on as a testament to the brand's willingness to experiment and its unique place in the culture of the British Isles. It was a perfect marriage of two beloved, and notoriously strong-flavoured, products.
