What is a fifth?

A fifth is a unit of volume measurement typically used in the United States for alcoholic beverages. It is equivalent to one-fifth of a gallon, which is approximately 750 milliliters or 25.36 fluid ounces. In terms of standard liquor bottle sizes, a fifth is slightly smaller than a standard 750ml bottle of wine.

The term "fifth" originates from the fact that it represents one-fifth of a gallon. It is commonly used to measure the volume of spirits such as whiskey, rum, vodka, and other distilled beverages. A fifth is often referred to as a "handle" due to the fact that many liquor bottles of this size come with a handle for easy pouring.

Fifths are a popular size for purchasing liquor for personal consumption or for gifting. They are also commonly used by bars and restaurants for serving drinks to customers. While the term "fifth" is still widely used in the United States, many countries now use the metric system for volume measurements and may refer to this size as a 750ml bottle instead.
