This may be shown to contain up to 50 different components, where the chief constituents are isobutanol (2-methyl-1-propanol), propanol, and above all, the pair of isoamylalkohols: 2-methyl-1-butanol and 3-methyl-1-butanol. The latter two form from the amino acids isoleucine and leucine by protein degradation during fermentation (fig.
