Understanding the Fifth of Whiskey
The term "fifth" is a historic unit of measurement that originated in the United States, where it referred to one-fifth of a U.S. liquid gallon. Today, this measurement has been largely superseded by the metric system, and a fifth is now standardized as a 750-milliliter bottle. For those more familiar with imperial units, 750ml is equivalent to approximately 25.4 fluid ounces. This bottle size is the most common for most types of spirits, including whiskey, and is a staple in both retail stores and bars. Knowing that a fifth is a 750ml bottle is the first step toward accurately calculating the number of drinks it contains.
Calculating the Number of Standard Drinks
To determine the number of drinks in a fifth, we must first establish a standard pour size. In the United States, a standard shot of liquor is officially recognized as 1.5 fluid ounces. The calculation is straightforward:
- Total ounces in a fifth: 25.4 fl oz
- Standard shot size: 1.5 fl oz
- Calculation: 25.4 ÷ 1.5 ≈ 16.93
This means that a fifth of whiskey contains, on average, about 17 standard 1.5-ounce shots. It's a useful number for party planning or for tracking consumption. However, it is important to remember that this number is an estimate based on a precise pour. In reality, factors like free-pouring versus using a jigger, or slight variations in shot glass size, can cause the number to vary slightly.
Factors Affecting Your Pour Count
While 17 is the general rule of thumb, several variables can influence the actual number of servings you get from a bottle. Being aware of these factors helps ensure accuracy when mixing cocktails or hosting an event.
- Pouring Technique: The way you pour has a significant impact. Free-pouring, where a bartender estimates the amount, is less precise than using a measuring tool like a jigger. A heavy hand can easily result in larger-than-standard pours, yielding fewer drinks from the bottle.
- Drink Type: The number of servings changes depending on whether you're serving straight shots, cocktails, or drinks on the rocks. A whiskey sour might call for a 2-ounce pour, while a whiskey neat might be a 1.5-ounce standard pour.
- Measurement Tool: Using a proper jigger is the most reliable way to achieve consistent pours. Bartender jiggers often have different measurements on each side, such as 1 ounce and 1.5 ounces, allowing for precise control.
- Drinker Preference: Some hosts or individuals may prefer a smaller or larger shot size. If you serve 1-ounce pours, you could get up to 25 drinks, whereas 2-ounce pours would drop the total to about 12.5 drinks.
Comparison of Whiskey Bottle Sizes
To provide a broader context, here is a comparison of how many standard 1.5 oz shots you can expect from other common liquor bottle sizes:
| Bottle Size | Volume (ml) | Volume (fl oz) | Approx. 1.5 oz Shots |
|---|---|---|---|
| Miniature / Nip | 50 ml | 1.7 oz | 1 |
| Half Pint | 200 ml | 6.8 oz | 4 |
| Pint | 375 ml | 12.7 oz | 8 |
| Fifth / Standard | 750 ml | 25.4 oz | 17 |
| Liter | 1000 ml | 33.8 oz | 22 |
| Handle / Half Gallon | 1750 ml | 59.2 oz | 39 |
The Difference Between a Shot and a Standard Drink
While a shot is a term often used interchangeably with a standard drink, there are some important distinctions to be aware of. A "standard drink" in the United States contains about 0.6 fluid ounces of pure alcohol. For 80-proof (40% ABV) spirits like most whiskeys, this equates to a 1.5-ounce pour. This is why a standard shot glass size of 1.5 ounces was established. However, whiskeys can come in higher proofs, which would mean a smaller serving size is necessary to equal one standard drink in terms of pure alcohol content. For example, a higher proof whiskey like 100-proof would require only a 1.2-ounce pour to be considered one standard drink. Most casual drinkers, however, simply stick to the 1.5-ounce serving regardless of the whiskey's proof, which is fine for mixing cocktails or for personal consumption but important to note for accurate alcohol intake tracking.
Pouring for Your Cocktails
When preparing cocktails, the number of drinks from a fifth will change. Many cocktail recipes use different volumes of whiskey, such as a 2 oz pour for an Old Fashioned or Manhattan. If you're mixing drinks, it's best to calculate the total number of servings by dividing the total ounces in the fifth (25.4) by the specific pour size for your recipe. Using a jigger is highly recommended for consistent and professional-tasting results. The more precise you are with your measurements, the more accurate your drink count will be.

Conclusion
In summary, a fifth of whiskey contains approximately 17 standard 1.5-ounce drinks. This widely used bottle size (750ml or 25.4 oz) is perfect for parties and home bartending. The final count can vary based on your pouring method, the size of your shot, and whether you are serving straight pours or mixed drinks. For best results and consistent cocktail quality, always measure your pours. By understanding these simple calculations, you can confidently prepare for any event and serve drinks with precision.
How many drinks are in a fifth of whiskey? - A Quick Guide
Standard Fifth Size: A "fifth" is a 750ml bottle, equivalent to 25.4 fluid ounces. Standard Shot Size: In the U.S., a standard shot is 1.5 fluid ounces. Calculation: A fifth contains about 17 standard 1.5-ounce shots (25.4 / 1.5 ≈ 17). Factors Affecting Count: The total number of drinks can vary based on your pouring technique and the specific pour size you use. Measurement Tools: For the most accurate count, use a jigger to measure your pours precisely. Responsible Drinking: Always be aware of your consumption, as the total alcohol intake from a fifth can be significant. Global Variations: Shot sizes differ internationally; for instance, a UK shot is smaller, so a fifth yields more servings there.
