Alcohol units are a way to measure the amount of pure alcohol in a drink, helping people to keep track of their drinking and make informed decisions about their drinking habits. The number of units in a drink is based on its size and alcohol strength, or alcohol by volume (ABV). Spirits, such as vodka, are typically served in single (25ml) or double (50ml) measures. A single measure of vodka contains one unit of alcohol, while a double measure contains about two units. However, the ABV of vodka can vary, typically ranging from 35% to 40%, and different pubs and bars may use different measurements for their pours.
| Characteristics | Values |
|---|---|
| Single measure of vodka | 25ml |
| Double measure of vodka | 50ml |
| Number of units in a single measure | 1 |
| Number of units in a double measure | 2 |
| ABV of vodka | 37.5% or more |
| ABV definition | Alcohol by volume |
| Definition of one unit of alcohol | 10ml or 8g of pure alcohol |
| Time taken to process one unit of alcohol | 1 hour |
| UK Chief Medical Officers' (CMO) low-risk drinking guidelines | No more than 14 units of alcohol a week |

What You'll Learn
A double vodka measure is 50ml
A double vodka measure of 50ml at 40% ABV contains about two units of alcohol. This is because a single 25ml measure is about one unit of alcohol. To calculate the number of units in a spirit, you can use the following formula: ABV x volume in ml divided by 1000. For example, 40 x 50ml divided by 1000 equals two units.
It's important to keep track of how many units of alcohol you're consuming, as drinking above the recommended guidelines can increase your risk of developing long-term health problems. The UK Chief Medical Officers' (CMO) low-risk drinking guidelines recommend that it's safest for both men and women to drink no more than 14 units of alcohol per week, spread over three or more days with several drink-free days. This is equivalent to about seven double vodka measures.
To help monitor your alcohol intake, you can use resources such as the MyDrinkaware app, which allows you to track your alcohol units and calories. Additionally, when drinking at home, it's a good idea to use a measuring cup to ensure accurate measurements. Alternating alcoholic drinks with soft drinks can also help slow the absorption of alcohol into your bloodstream.

A double vodka has two units of alcohol
The number of units in a drink is based on the size of the drink and its alcohol strength. Units were introduced in the UK in 1987 as a way of measuring the amount of pure alcohol in a beverage. One unit equals 10ml or 8g of pure alcohol, which is the amount of alcohol the average adult can process in an hour, though this varies from person to person.
It's important to understand how many units of alcohol you're drinking to drink alcohol safely. Units are a simple way of determining the quantity of pure alcohol in an alcoholic drink. The higher the number of units in the drink, the more pure alcohol it contains. This can help you to gauge your alcohol intake and make informed decisions about your drinking habits.
The UK Chief Medical Officers' (CMO) low-risk drinking guidelines recommend that it's safest for men and women to drink no more than 14 units of alcohol per week, spread over three or more days with several drink-free days. Drinking more than seven double vodkas in a week would exceed these guidelines and increase the risk of developing long-term health problems.

A single vodka measure is 25ml
In the UK, a single vodka measure is typically 25ml, which is considered one unit of alcohol. This is a standard measure for spirits, including gin, whisky, rum, and vodka. A "double" measure, on the other hand, is 50ml or two units of alcohol. It's important to understand these measures to monitor your alcohol intake and drink responsibly.
The concept of counting alcohol units was introduced in the UK in 1987 to help people keep track of their drinking. A unit is a simple way to express the quantity of pure alcohol in a drink. One unit equals 10ml or 8g of pure alcohol, which is roughly the amount metabolised by the average adult in an hour. This varies based on factors like body weight, metabolism, liver function, and food intake.
The number of units in a drink depends on its size and alcohol strength, represented as alcohol by volume (ABV). A pint of strong lager, for instance, has three units, while the same volume of lower-strength lager has about two units. ABV values commonly range from less than 0.1% in fruit juices to up to 98% in rare cases of spirits.
While there are no specified quantities for vodka servings, a single serving is typically 25ml or 35ml, as per the Weights and Measures Act (1985). However, some bars and pubs may serve spirits in 35ml measures, which is considered a "large" single and contains 1.4 units of alcohol.
Understanding alcohol units is essential for drinking responsibly and maintaining control over your alcohol consumption. It's a useful tool to ensure you stay within the recommended limits and minimise health risks associated with excessive drinking.

A single vodka has one unit of alcohol
It's important to understand how many units of alcohol are in your drink to monitor your alcohol intake and drink responsibly. Units are a simple way of expressing the quantity of pure alcohol in a drink. One unit of alcohol equals 10ml or 8g of pure alcohol, which is approximately the amount of alcohol the average adult can metabolise in an hour. This varies from person to person, depending on factors such as body weight, metabolism, and how much food has been consumed.
The alcohol content of vodka is typically expressed as Alcohol by Volume (ABV). In the UK, vodka must have a minimum of 37.5% ABV to be sold as vodka, and many bottles have an ABV of 37-40%. This means that a 25ml single measure of 40% ABV vodka contains one unit of alcohol.
It's important to remember that drinking too much alcohol can have negative health consequences. The UK Chief Medical Officers' (CMO) low-risk drinking guidelines recommend that men and women drink no more than 14 units of alcohol per week, spread over several days with drink-free days in between. Exceeding this limit increases the risk of developing long-term health problems, including heart and liver damage, higher risk of certain cancers, and adverse effects on appearance, fertility, and mental health.

ABV is a measure of alcohol content
To understand how many units of alcohol are in a double vodka, it is important to know what ABV is and how it is measured. ABV stands for Alcohol By Volume and is a metric used to determine the alcohol content in an alcoholic beverage. It is a measure of how much alcohol is contained in a volume of drink, expressed as a percentage of the entire drink. For instance, a bottle of beer with 4.5% ABV contains 4.5% alcohol.
ABV is calculated by measuring the volume of pure alcohol in a drink and dividing it by the total volume of the beverage. This ratio is then multiplied by 100 to obtain a percentage. For example, if a wine bottle contains 30 ml of pure alcohol in an 850 ml bottle, the ABV calculation would be:
> ABV = 30ml/850ml x 100 = 3.5%
The ABV of a drink is important as it helps determine the number of units of alcohol in the drink. Units of alcohol are a way of expressing the quantity of pure alcohol in an alcoholic drink. One unit equals 10ml or 8g of pure alcohol, which is roughly the amount of alcohol the average adult can process in an hour. So, a drink with a higher ABV will have more units of alcohol.
Spirits like vodka typically have a higher ABV, often between 35% and 50%. A double vodka measure is 50ml, and a 50ml measure of 40% ABV vodka would contain two units of alcohol.

Frequently asked questions
A double vodka typically contains two units of alcohol. This is based on a 50ml serving, which is considered a standard double measure.
ABV stands for Alcohol By Volume and is a measure of the amount of pure alcohol in a drink. The higher the ABV, the more units of alcohol in the drink. Vodka typically has an ABV of 37.5-40%, which means a 50ml double measure will contain two units of alcohol.
On average, it takes about one hour for an adult to process one unit of alcohol. However, this can vary depending on individual factors such as body weight, metabolism, and how much food you've eaten.
There are several tools available to help you monitor your alcohol intake, such as the MyDrinkaware app, Alcohol Change UK's unit calculator, and unit measure cups that you can purchase to accurately measure your drinks.
