Understanding Alcohol Units and the 14-Unit Guideline
An alcohol unit is a measure of pure alcohol content, and in the UK, one unit is defined as 10ml of pure ethanol. The UK weekly guideline for both men and women is to not regularly exceed 14 units of alcohol. This guideline is in place to help minimise health risks associated with excessive alcohol consumption. To put this into perspective, you can use a simple formula to calculate the units in any alcoholic drink.
The formula for calculating alcohol units is:
- (Volume in ml x ABV%) ÷ 1000 = Units
This simple equation allows you to accurately determine the unit count of any cider, regardless of its packaging or strength. For instance, a 500ml can of 5% ABV cider contains (500 x 5) ÷ 1000 = 2.5 units. Stronger ciders, with a higher ABV, will contain a greater number of units per volume, meaning fewer drinks are needed to reach the 14-unit weekly limit.
Calculating 14 Units in Cider by Strength
Since cider's alcoholic strength can vary widely, from around 3% to over 8% ABV, the number of drinks required to reach 14 units changes considerably. Below is a breakdown of how many ciders it takes to reach 14 units, based on common strengths and serving sizes found in the UK.
Examples of How Many Ciders Make 14 Units
- Low-Strength Cider (~4% ABV): A standard pint (568ml) of 4% cider contains approximately 2.3 units. To reach 14 units, you would need to consume around 6 pints.
- Standard-Strength Cider (~5% ABV): A pint of 5% ABV cider contains about 2.8 units. This means you would need approximately 5 pints to hit the 14-unit mark over the course of a week.
- High-Strength Cider (~7.5% ABV): A 500ml can of strong 7.5% cider has 3.75 units. To reach 14 units, you would need to consume just over 3.5 cans.
- Super-Strength Cider (~8% ABV): A pint of super-strength cider around 8% ABV contains 4.5 units. The total needed to reach 14 units would be approximately 3 pints. A large 2-litre bottle of 8% cider actually contains 16 units, exceeding the weekly guideline in a single container.
Comparative Table: Cider Volume for 14 Units
| Cider Strength (ABV) | Serving Size & Volume | Units per Serving | Servings for 14 Units |
|---|---|---|---|
| 4.0% | Pint (568ml) | 2.3 units | ~6 pints |
| 5.0% | Pint (568ml) | 2.8 units | ~5 pints |
| 5.5% | Can (500ml) | 2.8 units | 5 cans |
| 7.5% | Can (500ml) | 3.75 units | ~3.7 cans |
| 8.2% | Bottle (500ml) | 4.1 units | ~3.4 bottles |
| 8.4% | Can (330ml) | 2.8 units | 5 cans |
Health Implications of Exceeding Guidelines
Regularly consuming more than 14 units a week can increase your risk of developing long-term health issues. These include certain types of cancer (like breast, bowel, and mouth cancer), heart problems, and high blood pressure. It is crucial to remember that the 14-unit guideline should be spread over at least three or more days, with several alcohol-free days, rather than consumed in a single session. Binge drinking, defined by the NHS as more than 8 units for men and 6 for women in one session, carries its own set of significant health consequences.
For more detailed information on units and health risks, refer to authoritative sources like the NHS. Knowing your limits is an important part of a healthy lifestyle. Factors such as age, size, gender, and overall health also influence how alcohol affects you, so it's always best to stay mindful of your consumption.

Conclusion
There is no single answer to how many ciders are 14 units, as the volume depends entirely on the cider's ABV. As a rule of thumb, it can take anywhere from just over three pints of a super-strength cider to six pints of a lower-strength version to reach the 14-unit weekly guideline. The key is to check the ABV on the label of your chosen beverage and either use the simple calculation or consult a unit guide. Spreading your alcohol intake over several days is also essential for minimising health risks, and the most important thing is to stay aware of what you are consuming to maintain healthy habits.
