Beer is largely Ethanol (an alcohol molecule) which is produced from glucose.
Glucose --→ Ethanol + carbon dioxide (a form of anaerobic respiration)
- The microorganism that does this is Yeast which supply’s the enzymes
Ethanol is flavoured by plants such as Hops
Glucoses comes from starch
Starch ----(amylase ‘germination;)--→ Maltose ----(Maltose)---→ Glucose
The starch comes from things such as barley seeds, wheat seeds, and rice.
Yeast brings about the anaerobic respiration of glucose to ethanol and carbon dioxide
