Whisky has two legitimate spellings: “Whisky” and “Whiskey”. The Scots spell it without the "e" because they believe more vowels waste good drinking time.
If the bottle is written «whisky» it is precisely manufactured in Scotland, if «whiskey», then where else, but not in Scotland.
A bottle of whiskey can be kept 100 years, without losing the taste of the drink. After opening the whiskey can be kept for 5 years
Experts advise to drink Single Malt Whisky pure or with a tiny bit of water on room temperature. This is because of the maturing process that has taken place in oak casks for 10 – 15 years. If you drink it with ice or mix it with another drink this whole process was useless.
