There are 4 basic types of whiskies based on geography: American, Canadian, Irish, and Scotch whiskies, of which bourbon is the most important. Each whiskey is completely different from the rest. Each of their distinctive styles truly shows the country they are from.
Whiskies are also produced in other countries like Australia and Japan, but they are pretty exclusive, and you would mostly only drink them if you are planning a lovely vacation over to one of those countries. The difference between whiskey and whisky is nothing really at all.
You will find both spellings on labels, and both spellings are correct. “Whisky” is used by the Canadian and Scottish companies, while “whiskey” is used by most of the American and Irish producers. Nobody really seems to know why this had transpired over the years, though it doesn’t seem to have affected the quality of the whiskies.
Canadian Whisky:
This is a type of whisky that is produced in Canada. Most Canadian whiskies are blended multi-grain liquors containing a larger percentage of corn spirits, and are typically lighter and smoother than other whisky styles.
Irish Whiskies:
This whiskey was made on the island of Ireland. Most Irish pot still whiskey is distilled thrice, while most, but not all Scotch whiskey is distilled twice. Peat is rarely used in the malting process, so that Irish whiskey has a smoother finish as opposed to the smoky, earthy overtones common to some Scotches.
Scotch Whiskies:
Often called Scotch, this is a malt whisky or grain whisky made in Scotland. Scotch whisky must be made in a manner specified by law. All Scotch whisky was originally made from malted barley. All Scotch whisky must be aged in oak barrels for at least 3 years. Most Scotch whisky drinkers will refer to a unit for drinking as a dram.
