| Back | - malting (enzymes break down starch into sugars when barley germinates, seeds killed but enzyme activity retained to form malt) - mashing (malt mixed with hot water so enzymes break down starch into wort which needs to be steralised) - fermentation (wort inoculated with yeast, which is inhibited by dec in pH, build up of ethanol and lack of O2) - maturation (beer conditioned in tanks) - finishing (beer filtered, pasterised and bottled with addition of CO2) |
