Marmite was conceived in 1902 and the Marmite Food Company opened a small factory in Burton-on-Trent where it still resides today. Marmite is a nutritious, black, tasty, savoury spread enjoyable on toast or bread or even as a cooking ingredient. It is made from spent brewer's yeast and comes in a distinctive black jar with a yellow lid. Each order contains one (1) 250g jar.
