Scotch Whisky Quiz: Test Your Knowledge

Under the Scotch Whisky Regulations 2009, the five statutory protected geographical regions are Speyside, Islay, Highlands, Lowlands, and Campbeltown. While the "Islands" (Skye, Orkney, Jura, etc.) are culturally celebrated, legally they are classified under the Highlands region.

To legally carry the title Single Malt Scotch Whisky, the spirit must be batch distilled in copper pot stills at a single distillery using 100% malted barley, water, and yeast, with no other grains permitted.

First established by the Immature Spirits (Restriction) Act of 1915 and reiterated in modern law, Scotch spirit must mature in oak casks in Scotland for at least three full years before it can be legally sold as Scotch whisky.

Under both UK and EU law, Scotch whisky must have a minimum alcoholic strength by volume of 40.0% (80 proof). Spirits bottled below 40% cannot legally bear the label Scotch Whisky.

The Scotch Whisky Regulations explicitly stipulate that oak casks must not exceed 700 litres (185 US gallons) in capacity. This ensures a sufficient ratio of wood surface area to liquid during maturation.

A Blended Malt (such as Monkey Shoulder or Johnnie Walker Green Label) is produced by marrying single malts from two or more distinct Scottish distilleries. If column-distilled grain whisky is introduced, it becomes a "Blended Scotch Whisky".

Bruichladdich produces three distinct single malt profiles under one roof: unpeated Bruichladdich, heavily peated Port Charlotte (40 PPM), and super-heavily peated Octomore, whose single-field expressions have reached over 300 PPM of phenols.

Copper is a sacrificial chemical filter. During boiling and reflux, alcohol vapours react with copper to precipitate out smelly, harsh sulfur compounds (dimethyl trisulfide, hydrogen sulfide). Without copper contact, the new-make spirit would smell like rotten vegetables and boiled cabbage.

PPM is almost always measured on the dry malted barley after kiln smoking. During mashing, fermentation, distillation (where heavy phenols are held back in the pot), and cask aging, roughly 60% to 75% of those phenols are lost, meaning a 50 PPM malt yields roughly 15 to 20 PPM in the final glass.

Speyside is home to over 50 malt distilleries (including Macallan, Glenfiddich, Glenlivet, and Balvenie). Its abundance of pure granite-filtered snowmelt, proximity to fertile barley fields, and 19th-century railway links made it the beating heart of Scotch production.

Independent bottlers purchase mature or new-make casks from distilleries and curate them under their own independent label. They are venerated by enthusiasts because they frequently bottle at natural cask strength, without chill filtration, and without added E150a colouring, offering unique single-cask variations.

Batch pot stills distill spirit to roughly 68% to 72% ABV, carrying over rich esters, higher alcohols, and malt congeners that give single malts their deep character. Column stills distill continuously to nearly 94.5% ABV, producing a cleaner, lighter grain spirit designed to carry and balance heavy malts in blended Scotch.
