Mr Beale said the same thing I said but with different words, it has similarities to beer, not that it tastes like beer.
The comment about disliking beer and Vegemite has more to do with the way yeast tangs in the mouth than it does the actually taste.
Years ago when the yeast used actually came out of the beer factory it was a stinking, pungent, gagging, fucking smell that permeated the suburbs on a hot day, it was borderline gross the hotter it got. It was the sort of smell that put you off beer and yeast based products.
Not that I expect anyone to take my word for it when there is so many experts on the internet but I can tell you the beer sitting in front of me right now, which is made with the same formula that saw the need to get rid of the excess yeast and opened the 1922 competition that created Vegemite, tastes nothing like the paste I spread on my toast this morning.
