Free amino nitrogen

In brewing and winemaking, free amino nitrogen (FAN) is a measure of the concentration of individual amino acids and small peptides (one to three units) which can be utilized by beer and wine yeast for cell growth and proliferation. Together with ammonia, FAN makes up the measurement of yeast assimilable nitrogen that can be measured prior to the start of fermentation.
