Which of the following spirits typically has the highest proof?

Vodka is known for typically having the highest proof among the listed spirits. The proof of a spirit is a measure of its alcohol content, and vodka is usually distilled to a higher alcohol level than most other spirits, often reaching around 40% to 50% alcohol by volume (ABV) or even higher in some cases. This high level of alcohol contributes to its strong character and makes it a versatile base for many cocktails.

Whiskey generally has a lower proof, typically around 40% ABV, though some cask-strength whiskies can go higher. Rum varies widely in proof, depending on its style and production method, but standard rums often hover around similar alcohol levels to whiskey. Brandy usually also has an alcohol content within the range of 35% to 60% ABV, depending on the specific type and production techniques employed.

Thus, while all these spirits can be strong, vodka has the highest proof on average among them, making it the standout choice.
