The difference between Whisky and Whiskey is that the first is made on the UK mainland – generally in Scotland – and the second is imported, mainly from Ireland or America. Although, the general principle of production is the same, the two types are distinctly different, from the type of grain used, to the number of times the spirit is distilled. The main ingredients of Whisk(e)y are grain, water and yeast. The grain is fermented and then distilled before being put into casks for the maturation period. Blended whisky is made using a mixture of grain and malted barley, whereas Malt whisky is made using only malted Barley, giving it a more complex flavour.
