Alcohols

Alcohol is the popular designation for ethanol, which is formed from the grape sugar during fermentation of the rape Juice.

Along with ethanol, there are other, higher alcohols present in wine, which function as creators of aroma and taste (e.g. glycerol). If simple Rieslings are fermented at too high a temperature, they often exhibit a dull, piercing character, which can be attributed to excessive levels of there higher alcohols.
