What is the primary source of grape brandy?

The primary source of grape brandy is wine. Brandy is produced through the distillation of wine, which means that grapes are first fermented to create wine, and then that wine is heated in a still to produce brandy. During the distillation process, the alcohol content is increased, and unwanted elements are removed, resulting in a spirit that retains the flavors derived from the grape variety used in the wine.

Grape brandy specifically relies on the characteristics of the grapes, including their inherent sugars and flavors, which are converted into alcohol as the grapes are fermented into wine. This important connection helps differentiate grape brandy from other types of brandy, which may be made from different fruits or grains.
