fusel oil Normally a minor product of alcoholic fermentation, derived from amino acids but produced in larger amounts if nitrogenous nutrients, e.g. ammonium salts, are in poor supply. It is a minor normal component of the taste and smell of wine and beer, but is prominent in spirits such as whisky and brandy, and in excess can lead to hangovers. It is a mixture of higher alcohols, e.g. isoamyl alcohol.
