B.S. as usual from you!
Marmite originated in England in 1902, stemming from the discovery that yeast extract, a by-product of beer brewing, could be concentrated and eaten. The Marmite Food Company was established in Burton-upon-Trent, taking advantage of the town's many breweries. The name "Marmite" itself is derived from the French word for a large earthenware cooking pot, reflecting the original packaging.
