How Beer is Made. by Sara Doersam. Beer making dates back to 5,000 BC when yeast was discovered fermenting in a sugar-water mixture. The yeast consumes the sugar for its own energy and growth, and the primary byproducts are ethyl alcohol and carbon dioxide.ine is made when yeast consumes the natural sugars in fruit such as grapes, and beer is made when yeast consumes the sugar derived from grain. The naturally occurring starch found in grain must be converted into sugar before yeast can consume it.
