Single Malt Scotch Whisky

Single Malt whisky is Scotland's original whisky. It was traditionally made in the Highlands in the 18th and 19th century only from malted barley. In contrast, Lowland whisky was often made from other grains including oats, wheat, and later maize (corn). Until the Excise Act of 1823, a lot of Single Malt Whisky was produced and sold illegally. The passing of this act paved the way for the commercialisation of the industry when famed illicit distilleries like George Smith's Glenlivet went legal. This led to a boom in distillery building that continued until the 1890s.

How Single Malt was invented
Since a court ruling of 1909, Scotch whisky, both malt and grain, has to be aged for a minimum for three years. Now to be labelled as a 'Single Malt Scotch' whisky, the spirit has to be made only from malted barley, batch-distilled in copper pot stills (usually twice though there are some triple-distilled single malt Scotch whiskies), aged for a minimum of three years in oak casks in Scotland, and bottled at no less than 40% ABV. The industry is governed by the Scotch Whisky Association (SWA). Within these strict parameters, however, each distillery produces a unique style through differences in fermentation techniques, distillation, wood ageing etc. On the whole, the regional styles like Islay or Speyside owe more to tradition than anything intrinsic to where they are made.

Recent history of Single Malt
While for much of the 20th century, Scotch whisky drinkers would have drunk blends, often mixed with soda water, single malts were highly prized by aficionados, though usually only seen as independent bottling from merchants like Gordon & MacPhail of Elgin. In the 1960s, however, Glenfiddich in Speyside began bottling and marketing its single malt Scotch whisky internationally. Its success led to others making this leap such as Glenfarclas, Macallan and Glenlivet. Single malt Scotch whisky as we know it had arrived. Many of the distilleries built during the boom years of the 19th century have since closed down but in the 21st century Scotch whisky grew rapidly once more and there are now more than 130 malt distilleries in operation. These range from tiny farm operations to vast factories of whisky. Despite the global fame of single malt Scotch whisky, however, the majority of production is still used for blends which make up around 85% of global sales.

Scotch goes global
The success of single malt Scotch whisky has inspired distillers all over the world with countries such as Taiwan, Japan, Australia and America all making single malts that, while distinctive, owe much to the original. In the 19th century, characterful malt whiskies would have often been drunk mixed with hot water, honey and spices in the form of toddies. Nowadays, most are drunk neat or with a little water but we're starting to see a return to mixing with certain malt whisky cocktails like the Smokey Cokey, a blend of Lagavulin and Coca-Cola, gaining a cult following.
