The Marmite factory in Burton-on-Trent, Staffordshire, is more than just a production facility; it is the spiritual home of the iconic spread. Established in a disused malt house in 1902, the factory's location was no accident. Burton was the epicentre of British brewing, providing a vast and ready supply of the spent brewer's yeast that is Marmite's key ingredient.

The factory has been churning out the black stuff for over 120 years, its distinctive aroma a familiar feature of the local air. While the recipe is a closely guarded secret, the process involves breaking down the yeast cells, separating the extract, and adding a secret blend of vegetable extracts and spices.

For true devotees, a trip to Burton is something of a pilgrimage, a chance to get closer to the source of their favourite food. The factory stands as a monument to British industrial history and culinary eccentricity.
