Whisky (sometimes referred to as whiskey if you're in the US or Ireland) is a centuries-old drink enjoyed today by millions around the world. Typically with an ABV of 40%, whisky is produced from simple ingredients like barley and rye, but it offers a rewarding experience that no other spirit can offer. Usually brought to maturity or 'aged' within oak or bourbon barrels, whisky is unlike wine in that it doesn't age once bottled. This also means that it won't expire, providing that it is stored correctly and not opened.
