Whisky is a strictly regulated spirit worldwide with many classes and types. The typical unifying characteristics of the different classes and types are the fermentation of grains, distillation, and aging in wooden barrels.
Much is made of the word’s two spellings: whisky and whiskey. There are two schools of thought on the issue. One is that the spelling difference is simply a matter of regional language convention for the spelling of a word, indicating that the spelling varies depending on the intended audience or the background or personal preferences of the writer (like the difference between colour and colour; tire and tyre; or recognize and recognise), and the other is that the spelling should depend on the style or origin of the spirit being described. There is general agreement that when quoting the proper name printed on a label, the spelling on the label should not be altered. Some writers refer to “whisk(e)y” or “whisky/whiskey” to acknowledge the variation.
The spelling whiskey is common in Ireland and the United States while whisky is used in all other whisky producing countries. In the US, the usage has not always been consistent. From the late eighteenth century to the mid twentieth century, American writers used both spellings interchangeably until the introduction of newspaper style guides. Since the 1960s, American writers have increasingly used whiskey as the accepted spelling for aged grain spirits made in the US and whisky for aged grain spirits made outside the US. However, some prominent American brands, such as George Dickel, Maker’s Mark, and Old Forester (all made by different companies), use the ‘whisky’ spelling on their labels, and the Standards of Identity for Distilled Spirits, the legal regulations for spirit in the US, also use the ‘whisky’ spelling throughout.
“Scotch” is the internationally recognized term for “Scotch whisky”.
The art of distillation spread to Ireland and Scotland no later than the 15th century, as did the common European practice of distilling ‘Aqua Vitae’ or spirit alcohol primarily for medicinal purposes. The practice of medicinal distillation eventually passed from a monastic setting to the secular via professional medical practitioners of the time, The Guild of Surgeon Barbers. The first confirmed written record of whisky in Ireland comes from 1405, in the Irish Annals of Clonmacnoise, which attributes the death of a chieftain to “taking a surfeit of aqua vitae” at Christmas. In Scotland, the first evidence of whisky production comes from an entry in the Exchequer Rolls for 1494 where malt is sent “To Friar John Cor, by order of the king, to make aquavitae”, enough to make about 500 bottles.
James IV of Scotland (r. 1488â€“1513) reportedly had a great liking for Scotch whisky, and in 1506 the town of Dundee purchased a large amount of whisky from the Guild of Surgeon Barbers, which held the monopoly on production at the time. Between 1536 and 1541, King Henry VIII of England dissolved the monasteries, sending their monks out into the general public. Whisky production moved out of a monastic setting and into personal homes and farms as newly independent monks needed to find a way to earn money for themselves.
The distillation process was still in its infancy; whisky itself was not allowed to age, and as a result tasted very raw and brutal compared to today’s versions. Renaissance-era whisky was also very potent and not diluted. Over time whisky evolved into a much smoother drink.
With a licence to distil Irish whiskey from 1608, the Old Bushmills Distillery in Northern Ireland is the oldest licensed whiskey distillery in the world.
In 1707, the Acts of Union merged England and Scotland, and thereafter taxes on it rose dramatically.
After the English Malt Tax of 1725, most of Scotland’s distillation was either shut down or forced underground. Scotch whisky was hidden under altars, in coffins, and in any available space to avoid the governmental excisemen or revenuers. Scottish distillers, operating out of homemade stills, took to distilling whisky at night when the darkness hid the smoke from the stills. For this reason, the drink became known as moonshine. At one point, it was estimated that over half of Scotland’s whisky output was illegal.
In America, whisky was used as currency during the American Revolution; George Washington operated a large distillery at Mount Vernon. Given the distances and primitive transportation network of colonial America, farmers often found it easier and more profitable to convert corn to whisky and transport it to market in that form. It also was a highly coveted sundry and when an additional excise tax was levied against it, the Whiskey Rebellion erupted in 1791.
The drinking of Scotch whisky was introduced to India in the nineteenth century. The first distillery in India was built by Edward Dyer at Kasauli in the late 1820s. The operation was soon shifted to nearby Solan (close to the British summer capital Shimla), as there was an abundant supply of fresh spring water there.
In 1823, the UK passed the Excise Act, legalizing the distillation (for a fee), and this put a practical end to the large-scale production of Scottish moonshine.
In 1831, Aeneas Coffey patented the Coffey still, allowing for cheaper and more efficient distillation of whisky. In 1850, Andrew Usher began producing a blended whisky that mixed traditional pot still whisky with that from the new Coffey still. The new distillation method was scoffed at by some Irish distillers, who clung to their traditional pot stills. Many Irish contended that the new product was, in fact, not whisky at all.
By the 1880s, the French brandy industry was devastated by the phylloxera pest that ruined much of the grape crop; as a result, whisky became the primary liquor in many markets.
During the Prohibition era in the United States lasting from 1920 to 1933, all alcohol sales were banned in the country. The federal government made an exemption for whisky prescribed by a doctor and sold through licensed pharmacies. During this time, the Walgreens pharmacy chain grew from 20 retail stores to almost 400.
A still for making whisky is usually made of copper, since it removes sulfur-based compounds from the alcohol that would make it unpleasant to drink. Modern stills are made of stainless steel with copper innards (piping, for example, will be lined with copper along with copper plate inlays along still walls). The simplest standard distillation apparatus is commonly known as a pot still, consisting of a single heated chamber and a vessel to collect purified alcohol.
Column stills are frequently used in the production of grain whisky and are the most commonly used type of still in the production of Bourbon and other American whiskeys. Column stills behave like a series of single pot stills, formed in a long vertical tube. Whereas a single pot still charged with wine might yield a vapour enriched to 40â€“50% alcohol, a column still can achieve a vapour alcohol content of 95.6%; an azeotropic mixture of alcohol and water.
Whiskies do not mature in the bottle, only in the cask, so the “age” of a whisky is only the time between distillation and bottling. This reflects how much the cask has interacted with the whisky, changing its chemical makeup and taste. Whiskies that have been bottled for many years may have a rarity value, but are not “older” and not necessarily “better” than a more recent whisky that matured in wood for a similar time. After a decade or two, additional aging in a barrel does not necessarily improve a whisky.
While aging in wooden casks, especially American oak and French oak casks, whisky undergoes six processes that contribute to its final flavour: extraction, evaporation, oxidation, concentration, filtration, and colouration.
Extraction in particular results in whisky acquiring a number of compounds, including aldehydes and acids such as vanillin, vanillic acid, and syringaldehyde.
Most whiskies are sold at or near an alcoholic strength of 40% abv, which is the statutory minimum in some countries â€“ although the strength can vary, and cask-strength whisky may have as much as twice that alcohol percentage.
Whisky is probably the best known of Scotland‘s manufactured products. Exports have increased by 87% in the past decade and it contributes over Â£4.25 billion to the UK economy, making up a quarter of all its food and drink revenues. In 2012, the US was the largest market for Scotch whisky (Â£655 million), followed by France (Â£535 million). It is also one of the UK’s overall top five manufacturing export earners and it supports around 35,000 jobs. Principal whisky producing areas include Speyside and the Islay, where there are nine distilleries providing a major source of employment. In many places, the industry is closely linked to tourism, with many distilleries also functioning as attractions worth Â£30 million GVA each year.
In 2011, 70 per cent of Canadian whisky was exported, with about 60 per cent going to the US, and the rest mostly to Europe and Asia. 15 million cases of Canadian whisky were sold in the US in 2011.
