Fusel alcohol

Fusel Alcohol

Fusel alcohol, also known as fusel oil, is a mixture of several alcohols (chiefly amyl alcohol) produced as a by-product of alcoholic fermentation. The term 'fusel' is German for 'bad liquor'.

Production

Fusel alcohols are produced as a by-product of fermentation by good yeast. The concentration of fusel alcohols — it's higher in distilled beverages — is an indicator of the quality of the beverage's production.

Characteristics

Fusel alcohols are a mixture of several alcohols (chiefly amyl alcohol) produced as a by-product of alcoholic fermentation. They are found in small quantities in most distilled alcoholic beverages, although they are often removed in the production of more refined drinks.

Health Effects

Fusel alcohols have been associated with the 'hangover' effects of excessive alcohol consumption, and can be mildly toxic. They are also thought to contribute to the flavor and aroma of certain types of alcoholic beverages.
