THE CONTINUOUS BREWING OF BEER Beer is produced commercially by the controlled fermentation of wort‚ a liquid rich in sugars‚ nitrogenous compounds‚ sulphur compounds and trace elements extracted from malted barley. Fermentation is the process by which glucose is converted to ethanol and carbon dioxide and is expressed chemically as: C6H12O6 + 2PO43- + 2ADP → 2C2H5OH + 2CO2 + 2ATP Behind this simplified chemical reaction is a series of complex biochemical reactions. These reactions (known as the
