The words whisky and scotland have been tied together since the beginning and it could most likely be true that whisky originated from Scotland. What is definite is that the majority of the production of whisky worldwide comes from the numerous distilleries all across Scotland. In the recent years however, there are more countries that produce whiskies and account for a considerable percentage of the overall whisky production in the world.
Similar to wine, the characteristics, flavour profiles of whiskies are tied to their location. There are approximately more than 120 licensed distillers and they can be broken up into 6 regions, Highlands, Lowlands, Speyside, Islay, Islands & Campbeltown. Some of the flavour profiles overlap betwen different regions, however the locations are still important in understanding why it turns out the way it does.
