1
Q
what is alcohol fermentation?
A
the process where yeast breaks glucose down into ethanol and carbon dioxide in an anaerobic environment, producing energy
C6H12O6 –> 2CO2 + 2C2H5OH + energy
2
Q
what is ABV
A
alcohol by volume
percentage of alcohol (ethanol) in the beverage
3
Q
what is OG
A
original gravity
measure of density of liquid before fermentation (how much sugar can be fermented)
4
Q
what is FG
A
final gravity
measure of density of liquid after fermentation (how much sugar has been converted to alcohol)
5
Q
calculate ABV
A
ABV (%) = (OG - FG) * 131.25
