The alcohol proof system feels like an arcane ritual designed to confuse, but the conversion is surprisingly straightforward, almost disappointingly so. If you’re holding a bottle that states 40% alcohol by volume (ABV), then it is always 80 proof. There’s no trick, no regional variation in this specific calculation; it’s a direct, fixed mathematical relationship. […]
Despite what outdated information or international variations might suggest, 40 percent alcohol by volume (ABV) is exactly 80 proof in the most commonly accepted system used today for spirits.

This is the truth about whiskey ABV for the […]
