Bubbling “BeerBots” could boost the brewing of beer
The longer it takes to brew a batch of beer, the greater the chances of microorganisms getting in and ruining the whole thing. In order to speed up and simplify the process, scientists have developed tiny BeerBots.When making beer, brewers start by extracting sugars from grains such as barley, resulting in a solution known as wort. Yeast is then added to the wort, where it ferments the sugars and thus converts them into alcohol and flavor compounds.The fermentation process takes up to four weeks, during which time…
