The Global Variation in Shot Sizes
The most confusing aspect of measuring alcohol is that a "shot" is not a standardized unit of measurement worldwide. Its volume is determined by local laws, customs, and the establishment serving the drink. This means that 50ml can represent different things in different countries, causing understandable confusion for both drinkers and bartenders.
50ml as a US "Nip" or Oversized Single
In the United States, the commonly accepted standard for a single shot is 1.5 fluid ounces, which equates to approximately 44 milliliters. A 50ml bottle, often called a "nip" or "miniature," is a common retail size that is just slightly larger than this standard pour. For most practical purposes in the US, a 50ml serving of whiskey would be considered a single, if slightly generous, shot. A US double shot would typically be 3 ounces, or around 89ml.
50ml as a UK "Double" Shot
The United Kingdom has specific legal requirements for serving spirits in licensed establishments. Here, a standard single measure is either 25ml or 35ml, with 50ml being the standard measure for a double shot. Therefore, in the UK, 50ml of whiskey is consistently a double shot, representing a significantly larger portion than a single pour.
50ml as a Russian "Single" Shot
In contrast to the US and UK, 50ml is the widely accepted standard size for a single shot in Russia. This cultural norm is often associated with the tradition of drinking vodka, but it applies to other spirits like whiskey as well. This highlights how a single volume measurement can carry different cultural weight and meaning around the world.
Using a Jigger for Precise Measurement
For home bartenders and cocktail enthusiasts, relying on shot glass markings can be unreliable due to the global variations in size. The best way to ensure accuracy is to use a jigger, which is a standardized bar tool for measuring spirits. Jiggers are available in a variety of sizes and markings (e.g., 1 oz, 1.5 oz, 2 oz), allowing for precise pours regardless of location or recipe. This tool is essential for creating balanced cocktails and controlling alcohol consumption.
Here are some common measurements for home bartending:
- Miniature (50ml): Considered one US shot or a UK double.
- Quarter Pint (100ml): Approximately two 1.5 oz shots in the US.
- Standard Bottle (750ml): Typically yields about 17 standard US shots.
- Liter (1000ml): Contains roughly 22 standard US shots.
50ml and Standard Drink Guidelines
It is crucial to distinguish between a volumetric "shot" and a "standard drink." Many countries, including Australia and Ireland, use the concept of a standard drink to communicate alcohol content based on grams of pure alcohol, not just volume. A standard drink may not correspond perfectly to a shot glass pour. For instance, in Australia, a 30ml nip of 40% ABV spirits is considered one standard drink. A 50ml pour of whiskey, depending on its alcohol by volume (ABV), will almost always contain more than one standard drink. Always check the bottle label and local health guidelines to accurately track alcohol intake.

| Feature | United States | United Kingdom | Russia |
|---|---|---|---|
| Single Shot | 1.5 oz (~44ml) | 25ml or 35ml | 50ml |
| 50ml Whiskey | Generous single "nip" | Standard double shot | Standard single shot |
| Measurement Standard | Varies by state; 1.5 oz is common bar practice | Legally defined 25ml or 35ml single; 50ml double | 50ml is customary |
Conclusion
The simple question of how many shots is 50ml of whiskey has no single, universal answer. It serves as a prime example of the differences in international drinking customs and legal regulations. What is a standard single shot in one country may be a double in another, or even just a "miniature" bottle. For consistent pouring, especially when mixing drinks at home, a jigger is the most reliable tool. For responsible drinking, understanding the local definition of a "standard drink" is more important than the shot size itself.
