How Many Drinks Are In A Fifth? The Numbers

A standard fifth of liquor contains exactly 25.6 fluid ounces. That is the simple answer. But when people ask “how many drinks are in a fifth” they usually want to know how many cocktails or servings they can pour. For a 1.5-ounce shot — which is the standard US drink size — a fifth holds about 17 drinks. For a 2-ounce pour the number drops to roughly 12 to 13 drinks. The real answer depends on how you pour and what you are making. Let us break down the numbers so you know exactly what you are working with.

What Exactly Is a Fifth of Liquor?

A fifth is an old name that stuck. It comes from the fact that these bottles used to hold one-fifth of a gallon. That equals 25.6 fluid ounces. Today most liquor bottles are metric. A standard fifth is 750 milliliters. That converts to 25.36 fluid ounces. The difference is tiny — about a quarter of an ounce — so most people round it to 25.6 ounces for practical use.

The US government defines a standard drink as 0.6 fluid ounces of pure alcohol. For 80-proof liquor — which is 40% alcohol by volume — a standard drink is 1.5 ounces. So a 750 ml bottle of 80-proof whiskey, vodka, or gin gives you about 17 standard drinks. That is the number most people are looking for.

But not all liquor is 80 proof. Higher proof bottles contain more alcohol per ounce. A 100-proof bottle — 50% alcohol — has roughly 21 standard drinks per fifth because each 1.5-ounce pour contains more alcohol. The math changes with the proof.

How Many Drinks Are In a Fifth Based on Pour Size?

The number of drinks you get from a fifth depends entirely on how much you pour. Most home bartenders pour heavier than a standard 1.5-ounce shot. If you pour 2 ounces per drink — which is common for cocktails like an old fashioned or a martini — a fifth gives you about 12 to 13 drinks. If you pour 3 ounces — typical for a wine glass of liquor over ice — you get roughly 8 to 9 drinks.

Here is a quick reference table for a 750 ml bottle of 80-proof liquor:

These numbers assume no spillage and that you fill each pour exactly. In real life people tend to pour a little extra. If you are planning a party expect to get slightly fewer drinks than these numbers suggest.

Does the Type of Liquor Change the Count?

The alcohol content matters more than the type of liquor. A fifth of 80-proof vodka and a fifth of 80-proof whiskey both contain the same amount of alcohol. They both yield 17 standard drinks at 1.5 ounces each. The difference is in how people drink them. Vodka is often mixed into tall drinks with larger pours. Whiskey is often sipped neat or on the rocks in smaller amounts.

Liqueurs and cordials are different. They are usually lower proof — around 30 to 60 proof — so a standard drink is a larger volume. For a 60-proof liqueur a standard drink is about 2 ounces. That means a fifth of lower-proof liqueur gives you roughly 12 to 13 standard drinks. Always check the proof on the bottle label before calculating.

Cream liqueurs like Baileys are even lower proof — around 34 proof. A standard drink for Baileys is about 3.5 ounces. So a fifth of cream liqueur gives you roughly 7 standard drinks. The bottle size is the same but the alcohol content is much lower.

How Many Mixed Drinks Can You Make From a Fifth?

Mixed drinks are where the math gets fuzzy. A cocktail like a margarita uses 2 ounces of tequila. A gin and tonic typically uses 1.5 to 2 ounces of gin. A highball like a rum and coke often uses 1.5 ounces. So for most standard cocktails you get between 12 and 17 drinks per fifth.

But many cocktail recipes call for multiple types of liquor. A Long Island Iced Tea uses four different spirits. That changes the math entirely. You cannot just count ounces of one bottle. You have to account for the total alcohol across all ingredients.

Here is a practical breakdown for common cocktails using a single 750 ml bottle:

• Simple mixers (vodka soda, gin and tonic): 12 to 17 drinks
• Standard cocktails (margarita, old fashioned, martini): 10 to 13 drinks
• Strong cocktails (Manhattan, negroni): 8 to 10 drinks
• Shots or straight pours: 17 to 25 drinks depending on pour size

The takeaway is simple. If you are making cocktails expect fewer drinks than the standard shot count. Cocktails use more liquor per serving and often include additional ingredients that dilute or change the alcohol concentration.

What About Wine and Beer Comparisons?

A standard drink of wine is 5 ounces. A standard drink of beer is 12 ounces. A fifth of liquor contains the same amount of alcohol as roughly 17 beers or 17 glasses of wine at standard serving sizes. That is because one 1.5-ounce shot of 80-proof liquor equals one 12-ounce beer at 5% alcohol or one 5-ounce glass of wine at 12% alcohol.

This comparison only works at standard alcohol percentages. A craft beer at 8% alcohol is not equal to a standard shot. A high-alcohol wine at 15% is not equal either. The US standard drink definitions assume typical alcohol content for each category. If your drink is stronger than average the math changes.

The CDC uses these standard drink definitions for public health guidelines. They state that moderate drinking means up to one drink per day for women and up to two drinks per day for men. A fifth of liquor contains roughly 17 of those standard drinks. That is more than a week’s worth of moderate drinking for one person.

Common Misconceptions About Fifths and Drink Counts

One common myth is that a fifth holds exactly 20 drinks. That number comes from an old marketing trick. Some bars used to advertise that a fifth of cheap liquor would make 20 shots. They poured 1.25-ounce shots instead of the standard 1.5 ounces. That is not a real standard drink. It is a way to make the bottle seem more economical.

Another misconception is that a fifth equals a liter. It does not. A liter is 33.8 ounces. A fifth is 25.6 ounces. A liter bottle gives you roughly 22 standard drinks. That is about 5 more drinks than a fifth. If you are comparing prices always check whether the bottle is 750 ml or 1 liter. The difference matters.

Some people also think that a “handle” — which is 1.75 liters — is the same as a fifth. It is not. A handle holds roughly 2.3 times as much as a fifth. A handle gives you about 39 standard drinks. That is more than double the drinks from a fifth. The names are confusing so always look at the volume on the label.
