Which term describes wine produced without any added water, specifically in relation to whiskey?

The term "Cask Strength" refers to whiskey that is bottled directly from the cask without any dilution, meaning that no water has been added to the final product. This results in a whiskey that retains its full potency and flavor profile as it was intended by the distiller. The cask strength can vary significantly between bottles, depending on the age and the particulars of the maturation process. This term emphasizes the authenticity and natural characteristics of the spirit, making it a favorite among enthusiasts who appreciate that unaltered experience.

In contrast, "Barrel Proof" essentially means the same as cask strength; however, it typically refers to bourbon and may not be as commonly used across all types of whiskey. "Single Malt" pertains specifically to whiskey produced at a single distillery using only malted barley, while "High Proof" simply indicates that the whiskey has a higher alcohol content than normal, without specifically denying the addition of water.
