What is the difference between alcohol and liquor?

The terms "alcohol" and "liquor" are often used interchangeably, but there's a subtle difference:

* Alcohol is a broad term referring to any beverage that contains ethanol, the intoxicating substance produced by fermentation. This includes beer, wine, spirits, and even some fermented foods like kombucha.

* Liquor is a more specific term, usually referring to strong alcoholic beverages, like spirits, which have a high alcohol content (typically over 20%). Examples include whiskey, vodka, gin, rum, and tequila.

Essentially, "liquor" is a subset of "alcohol." Think of it this way:

* Alcohol is the umbrella term.

* Liquor is a specific type of alcohol.

So, while all liquor is alcohol, not all alcohol is liquor.
