Wine is an undistilled product, produced due to the traditional alcoholic fermentation of fruit juices by yeast. Thus the concentratation of alcohol is less in wine. The other three drinks are formed only after distillation as follows.

Whisky: Fermentation of grain mill (barley, corn, rye and wheat)$\to$Distillation

Rum: Direct distillation of the byproducts of sugarcane or sugarcane juice.

Brandy: Distillation of fermented wine.
