What makes it Scotch?
Scotch whisky is a protected name. It must be mashed, fermented, distilled, and matured in Scotland. It is distilled below 94.8% ABV, matured in oak casks no larger than 700 litres for at least three years, and bottled at 40% ABV or more. Only water and permitted plain caramel colouring may be added to the finished whisky.
The five legal categories
| Sales description | Core requirement |
|---|---|
| Single Malt Scotch Whisky | One distillery; water and malted barley; batch-distilled in pot stills |
| Single Grain Scotch Whisky | One distillery; other cereals may be used alongside malted barley |
| Blended Malt Scotch Whisky | Single malts from two or more distilleries |
| Blended Grain Scotch Whisky | Single grains from two or more distilleries |
| Blended Scotch Whisky | One or more single malts blended with one or more single grains |
Single means one distillery, not one cask. Pure Malt is not one of the legal sales descriptions.
Regions and localities
The protected regions are Highland, Lowland, and Speyside; the protected localities are Campbeltown and Islay. Only Scotch distilled in the relevant place may use that name as its regional indication. Islands is a useful geographic shorthand, but it is not a separate protected region under the 2009 regulations.
A region tells you where a whisky was produced, not its quality or a guaranteed flavour. Malt, fermentation, stills, cut points, casks, and warehouses can create large differences within one region.
Age and vintage statements
- An age statement gives the age of the youngest whisky in the bottle.
- Only time spent maturing in an oak cask counts; whisky does not continue to mature in the bottle.
- A blend of several ages cannot claim an age older than its youngest component.
- A NAS Scotch still meets the general minimum of three years of maturation.
Start with the legal sales description, ABV, volume, origin, and any age statement. Terms such as Single Cask, Cask Strength, Natural Colour, and Non-Chill Filtered describe production or bottling choices; they are not additional legal Scotch categories.
