Vegemite  Vegemite ( ) is a thick, dark brown Australian food spread made from leftover brewers' yeast extract with various vegetable and spice additives. It was developed by Cyril Callister in Melbourne, Victoria in 1922. The Vegemite brand was owned by Mondelez International (formerly Kraft Foods Inc.) until January 2017, when it was acquired by the Australian Bega Cheese group in a agreement for full Australian ownership after Bega would buy most of Mondelez International's Australia and New Zealand grocery and cheese business. A spread for sandwiches, toast, crumpets and cracker biscuits as well as a filling for pastries, Vegemite is similar to British Marmite, New Zealand Marmite, Australian Promite, MightyMite, AussieMite, OzEmite, German Vitam-R, and Swiss Cenovis. Vegemite is salty, slightly bitter, malty, and rich in glutamates – giving it an umami flavour similar to beef bouillon. It is vegan, kosher, and halal. In 1919, following the disruption of British Marmite imports after World War I and prior to the introduction of Vegemite, Callister's employer, the Australian company Fred Walker & Co., gave him the task of developing a spread from the used yeast being dumped by breweries. Callister had been hired by the chairman Fred Walker. Vegemite was registered as a trademark in Australia that same year. Callister used autolysis to break down the yeast cells from waste obtained from the Carlton & United brewery. Concentrating the clear liquid extract and blending with salt, celery and onion extracts formed a sticky black paste. Following a competition to find a name for the new spread, the name "Vegemite" was selected by Fred Walker's daughter, Sheilah. Vegemite first appeared on the market in 1923 with advertising emphasising the value of Vegemite to children's health but failed to sell very well. Faced with growing competition from Marmite, from 1928 to 1935 the product was renamed as "Parwill" to make use of the advertising slogan "Marmite but Parwill", a convoluted pun on the new name and that of its competitor; "If Ma [mother] might... then Pa [father] will." This attempt to expand market share was unsuccessful and the name was changed back to Vegemite, but did not recover lost market share. In 1925, Walker had established the Kraft Walker Cheese Co. as a joint venture company with J.L. Kraft & Bros to market processed cheese and, following the failure of Parwill, in 1935 he used the success of Kraft Walker Cheese to promote Vegemite.
