1. Harvesting - cool climate favors the cultivation of barley
2. Cleaning - the barley is first carefully selected to contain 60% starch. It is then washed to separate it from the husk (dry covering of seeds) and is finally dried
3. Malting - the dried barley is soaked in warm water for two or three days. The barley is spread on the floor to germinate for 8 to 12 days till it sprouts a "shoot"-a thumbnail long. The sprouting barley is constantly turned by hand or by "Saladin" machine to aerate it
4. Drying and Grinding - germination is stopped at a certain time and the barley is subjected to heat over fires of smokeless coal and peat. The peat gives smoke, which flavors the malt during the process. The malt is then ground to form what is called grist
5. Mashing - the grist is mixed with warm water in a tank called the mash tun (a vat or tub). The sweetish liquid produced (wort) is drawn off and the remaining husky liquid, called draff is removed
6. Fermentation - the wort is cooled and then passed into vessels where it is fermented for 40 hours. Yeast is added to convert the maltose into glucose, which produces crude alcohol and carbon dioxide. The result is a sort of beer called the "wash", with an alcoholic strength of about 10%
7. Distillation - the wash is distilled twice in pot stills, the wash is heated with a lower boiling point than water becomes vapour, which is then cooled and condensed back into liquid. The distillates are combined with new wort for distillation
8. Maturation - the new whisky is poured into oak wood casks where it is matured into a pleasant mellow spirit for as long as 15 years, though not less than three years. Scotch matures during aging process, developing smoothness and improved character. Aging also gives colour of the barrel. Finer whiskies are matured in actual sherry or port casks or wine treated-treated casks. Most regular scotch is aged for 5 or 6 years while premium scotch undergoes this process for a minimum of 8 years. Premium Scotch takes the woody flavor of the barrel as it is aged for a longer period
9. Blending (optional) - after the whisky are matured, they are "married" to achieve consistent quality and bouquet. Blended with grain whisky that provides lightness; malt gives body and character; grain gives lightness
10. Filtering and Bottling - the Scotch whisky is finally filtered and bottled.
