Both Whisky and Whiskey are correct, however it depends where the Whisky in question is produced. It's actually quite a simple method that's used all over the World, if the country where the Whisky is produced has the letter E in the spelling, then it's spelt Whiskey (Ireland for example), but if the country spelling doesn't have an E then it's spelt Whisky (Scotland for example).
There are four different types of Whisky, Scotch, Bourbon, Tennessee and Rye. The difference between the four is a mixture of materials that's used with the mix, how they are filtered / distilled and of course the geographic difference of where they are made.
Scotch whisky is made in Scotland (hence the name), while bourbon is whiskey that’s made in the USA, most commonly in the central eastern state of Kentucky. Scotch is made mostly from malted barley, whereas Bourbon is distilled from corn. The difference between Tennessee Whiskey and Bourbon is that once the spirit has been distilled, Tennessee Whiskey is filtered through sugar-maple charcoal, giving it a sugar / sweeter taste. Bourbon can only be made in brand new oak barrels once, this legal requirements means they are a popular purchase for many distilleries in Scotland.
Whisky does not age within the bottle, it ages within the cask. For example, a 10 year old Whisky has been 'casked' for 10 years and then bottled, unlike with Wine the year that it has been bottled won't make a difference to the taste.
Every Whisky is casked for different amounts of time. T the more expensive whiskies would generally have been casked for a longer period of time and the time it's taken to mature would have then affected the price.
Adding water to whisky is a personal preference, by doing so the whisky becomes a little smoother and the nosing aromas more apparent as it reduces the alcohol strength. A dash or even just a few drops of water is often enough to make a difference to the taste, smell and look of your whisky.
Traditionally there are 5 main countries around the World that produce Whisky, Scotland, Ireland, United States of America, Canada and Japan. Many others in recent years are joining the elite few and Whisky is now also made across Europe and every other continent.
