Before examining what is Hennessy proof specifically, it’s important to understand how alcohol proof works as a measurement system. Proof represents the alcohol strength of spirits and varies depending on the measurement system used.

American vs British Proof Systems

The United States uses a proof system where proof equals twice the alcohol by volume (ABV) percentage. In contrast, the British system calculates proof differently, though it’s less commonly used today.

Why Proof Matters for Spirits

Understanding proof helps consumers gauge the strength, flavor intensity, and appropriate serving methods for different spirits. Higher proof spirits typically offer more intense flavors and require different serving considerations.
