Terminology
ABV, angel's share, pot still, grain whisky: the vocabulary of whiskey
Whiskey is one of the most regulated and regionally diverse spirits in the world. From the strict legal definitions of Bourbon (51% corn, new charred oak, United States) and Scotch (malted barley, Scotland, minimum three years) to the meticulous craft of Japanese whisky distillers who modelled their production on Scottish methods, each tradition has a distinct technical identity worth understanding in depth.
The subject rewards close study: pot still versus column still, single malt versus blended, cask influence, peat levels, and the chemistry of long maturation all intersect in ways that have real sensory consequences. Regular practice with structured questions builds the kind of fluent recall needed to discuss whiskey confidently in professional, educational, or enthusiast contexts.
Frequently asked questions
- What legally makes a whiskey a Bourbon?
- US law requires Bourbon to be made from a mash of at least 51% corn, distilled to no more than 160 proof, and aged in new charred oak containers. It need not come from Kentucky, though most does.
- Whiskey or whisky — what's the difference?
- Mostly spelling by country. Scotland, Japan, and Canada use 'whisky'; Ireland and the United States generally use 'whiskey'. The product category is the same.
- What is the angel's share?
- The share of maturing spirit that evaporates from the cask each year — commonly around 2% annually in Scotland, and more in hotter climates. Over a long maturation it noticeably reduces volume and concentrates character.
