What You'll Learn

A fifth is 750ml
A fifth of alcohol is a unit of volume that was formerly used for wine and distilled beverages in the United States. It is equal to one-fifth of a US liquid gallon, or 757 milliliters. Today, the metric bottle size of 750 mL, sometimes called a metric fifth, is the standard capacity of wine bottles worldwide. This size is also the standard for spirits in the US.
The term 'fifth' comes from a time when bottles were four-fifths of a quart, which is the same as one-fifth of a gallon. In the late 19th century, one-fifth of a gallon was the legal threshold for individual commercial alcohol sales. Anything larger than that was considered wholesale. For this reason, fifths were also called commercial quarts.
A fifth of alcohol, or 750 mL, contains about 17 shots of liquor, 12.5 "whiskey neats" or "whiskey on the rocks", and enough alcohol for approximately 12 to 25 cocktails. This amount is also equivalent to about 25.4 ounces, or 25.36 ounces to be more exact.
A fifth is also the standard bottle size for whiskey, rum, vodka, tequila, and other liquors. It is the most popular bottle size for liquor, and you will often hear it referred to by manufacturers, bar owners, and bar patrons.

It's also 25.4 ounces
A "fifth" of alcohol is a unit of volume that was formerly used for wine and distilled beverages in the United States. It is equal to one-fifth of a US liquid gallon or about 25.4 fluid ounces (757 milliliters). The term "fifth" is derived from the past when liquor was measured in gallons, and a fifth was one-fifth of a gallon.
Today, the metric system is the standard for liquor measurements, but the term "fifth" is still commonly used, especially in the US. The standard size for liquor bottles is now 750 milliliters, which is also referred to as a fifth. This size bottle contains approximately 17 regular-sized shots, as a standard shot in the US is generally considered to be 1.5 ounces. Therefore, dividing the total number of ounces in a fifth (25.4 ounces) by the size of a standard shot yields approximately 17 shots.
The number of shots in a fifth can vary depending on the size of the shot glass. While the US standard shot is 1.5 ounces, shot glasses come in different sizes, and larger shot glasses will yield fewer shots from a fifth. It's important to know the size of your shot glass when calculating the number of shots in a fifth. Additionally, the difference between a single shot and a double shot should be considered. In the US, a single shot is typically 1.5 ounces, while a double shot is usually 3 ounces. Therefore, a fifth would provide approximately 17 single shots or 8.5 double shots.
Shot sizes can also vary significantly across the world. For example, in the United Kingdom, a standard shot is 25ml, while in Japan, it's 30ml. These differences will, of course, affect the number of shots that can be poured from a fifth.

It's a fifth of a gallon
A fifth of alcohol is a unit of volume that was formerly used for wine and distilled beverages in the United States. It is equivalent to one-fifth of a US liquid gallon or 25 and 3/5 US fluid ounces (750 milliliters). In simpler terms, a fifth of alcohol is 750 milliliters or 25.4 ounces. This is considered the standard size for most spirits like vodka, gin, and whiskey.
The term "fifth" is derived from a time when bottles were 4/5 of a quart, which is equal to 1/5 of a gallon. In the late 19th century, one-fifth of a gallon was the legal threshold for individual commercial alcohol sales. Anything larger than that was considered wholesale. For this reason, fifths were also referred to as commercial quarts.
A fifth of alcohol typically contains about 17 shots, 12.5 "whiskey neats" or "whiskey on the rocks", and enough alcohol to make approximately 12 to 25 cocktails. It's important to note that the number of drinks in a fifth depends on the type of drink being served.
Today, the metric bottle size of 750 mL, sometimes called a metric fifth, is the standard capacity for wine bottles worldwide. It is approximately 1% smaller than the traditional fifth. While the term "fifth" may be considered archaic, it is still commonly used by manufacturers, bar owners, and patrons.

It contains 17 shots
A fifth of alcohol is a unit of volume that was formerly used for wine and distilled beverages in the United States. It is equivalent to one-fifth of a US liquid gallon, or approximately 750 ml. This amount is the same as a standard wine bottle and is also known as a "metric fifth".
A fifth of alcohol contains approximately 17 shots of liquor. This is based on the assumption that a standard shot of alcohol is 1.5 ounces. With this measurement, a fifth of alcohol would provide about 17 shots.
However, it is important to note that the number of shots in a fifth can vary depending on the type of alcohol and the size of the shots. For example, a fifth of whiskey contains about 12.5 "whiskey neats" or "whiskey on the rocks", which are typically served in 2-ounce portions.
In addition to shots, a fifth of alcohol can also be used to make cocktails. A standard cocktail typically contains 1 to 2 ounces of liquor, so a fifth of alcohol can make approximately 12 to 25 cocktails.
While the term "fifth" may be considered archaic, it is still commonly used by manufacturers, bar owners, and patrons when referring to the standard 750 ml bottle size for spirits.

It's no longer the standard bottle size
A "fifth" of alcohol is a unit of measurement that was once commonly used to describe a bottle of liquor that contained one-fifth of a US liquid gallon, equivalent to 757 ml or 25.4 ounces. This measurement originated in the 19th century when the US government introduced a standardized system of weights and measures. However, the "fifth" is no longer the standard bottle size for liquor in the United States.
The transition away from the "fifth" as the standard bottle size began in the 1970s when the metric system started to influence packaging in the United States. Liquor producers began to realize that a 750-milliliter bottle, which is close to a metric quart and is also a common bottle size in wine, offered a more convenient and cost-effective option. This size also aligned better with international markets, making it easier for producers to export their products.
By the 1980s, the 750-milliliter bottle had become the new standard for liquor in the United States. This change was driven in part by consumer preference for the smaller size, as well as the growing influence of the metric system in global trade. The 750-milliliter bottle offered a more manageable and portable option for consumers, and it also allowed liquor producers to streamline their production and distribution processes.
Today, the 750-milliliter bottle is the most common size for liquor sold in the United States, although other sizes, such as 1-liter or 1.75-liter bottles, are also available. The "fifth" is now considered a legacy size, and while some liquor brands may still offer bottles in this size, it is no longer the predominant option on store shelves. The change in bottle size reflects the evolving preferences and needs of consumers, as well as the increasing globalization of the liquor industry.
While the "fifth" may no longer be the standard, it has certainly left its mark on the liquor industry and even popular culture. References to a "fifth" of liquor can still be found in literature, film, and music, reflecting its once-prominent place in American culture. Additionally, some collectors and enthusiasts may still seek out vintage bottles in this size, adding a touch of nostalgia to their liquor collections.
Although no longer the standard, the "fifth" of alcohol remains a reminder of the dynamic nature of measurement systems and the influence of cultural and economic factors on the goods we consume. The story of the "fifth" also highlights how even small changes in packaging size can have a significant impact on industries and consumers alike.
