[ 3 ] [ 4 ] Alcohols range from the simple, like methanol and ethanol , to complex, like sugar alcohols and cholesterol .
A general formula for calculating the resulting alcohol concentration by volume can be written: A B V = S B V f e r m e n t e d × G E C F {\displaystyle ABV=SBVfermented\times GECF} where SBV fermented is sugar by volume (g/dL) converted to alcohol during fermentation and GECF is the glucose-ethanol conversion factor:
The 3S,4S isomer, commonly known as whisky lactone or quercus lactone is an important ingredient in the aroma of whiskey (where it was first identified by Suomalainen and Nykänen in 1970) and other alcoholic beverages that have been aged in oak barrels.
