Useful takeaways from this story.

Scotch categories are legally defined: single malt, single grain, blended malt, blended grain and blended Scotch — each has clear production and origin rules.

Terms like first-fill and refill describe how much influence a barrel’s wood still has on the whisky’s flavour and colour.

The useful part

From different whisky styles to cryptic label wording and production nuances, it is easy to get lost. Thankfully, you do not need a shelf full of rare Scotch or a working knowledge of Speyside distilleries to make sense of it all. Learn a few basics and you will better understand what you are drinking, what you are buying and, crucially, what all those impressive-sounding words on the bottle actually mean.

How it works

  • Whichever category it falls into, Scotch must follow a strict set of rules.
  • Bourbon An American whiskey with strong historical roots in Kentucky, bourbon can actually be produced anywhere in the United States, provided it follows some strict rules.
  • To be labelled straight bourbon, however, it must spend at least two years in new charred oak.
  • Non-Chill Filtered Whisky contains naturally occurring compounds, including fatty acids and esters, that can cause it to become slightly cloudy when chilled or diluted with water.
  • If a bottle is marked non-chill filtered, the producer has skipped this step.

What to take from it

Single Malt Scotch Whisky, Single Grain Scotch Whisky, Blended Malt Scotch Whisky, Blended Grain Scotch Whisky and Blended Scotch Whisky. It has to be distilled and matured in Scotland, made using cereals, water and yeast, and aged in oak casks for a minimum of three years. Single Malt Single malt Scotch is produced at one distillery using water and 100% malted barley, with no other cereals added.

Example or evidence

  • It can include malted barley alongside other cereals, most commonly wheat or maize, and is typically produced using continuous column stills rather than pot stills.
  • Much of Scotland's grain whisky goes into blends, although standalone examples are available too.
  • It is a growing category that gives blenders the freedom to combine the characteristics of several distilleries in one bottle.
  • Blended Scotch A traditional blended Scotch combines one or more single malt whiskies with one or more single grain whiskies.

Details worth keeping

It must also be bottled at a minimum strength of 40% ABV. Single Malt Scotch Whisky must be bottled in Scotland. It is also batch distilled in copper pot stills.
