“Our data showed that home-brewed Vegemite beer could be easily made from sugar, Vegemite and yeast but not from just Vegemite and sugar, or sugar and yeast,” he said.

“The Vegemite added the nutrients necessary for the fermentation process, but there are also many other sorts of food apart from Vegemite — such as fruits or ginger — that could provide those additional nutrients.”

Schulz said that the brew left a distinct aftertaste and is very cheap to make and estimated that the real-world cost of Vegemite beer would be about 9 cents per 375 millilitres, compared with the retail cost of bulk commercial beer at about $1.60 for the same volume (via ABC.au).

“Vegemite beer is therefore substantially cheaper than other readily available products,” Dr Schulz added.

via Australian Vegemite can be brewed into crude moonshine beer.
