There are two myths about the origins of fermentation. The first is that the beer was "invented" or more accurately, discovered by chance. The second, that the wine was also an accident. It is highly unlikely that, given the elegantly simple and yet so complex brewing process, the beer was no more than a coincidence. The same goes for the wine, although it is likely that our ancestors watch how fruit juices changed when they were left to rot or decompose under certain conditions.
