How Many Units is a 330 ml Can of Beer?

When it comes to responsible drinking, understanding the number of alcohol units in a beverage is crucial. In this article, we will explore the number of units in a 330 ml can of beer and shed light on the implications for responsible consumption.


A 330 ml can of beer typically contains around 1.7 to 2.3 alcohol units, depending on the beer's alcohol by volume (ABV) percentage. The ABV refers to the amount of alcohol present in the beverage as a percentage of the total volume. Different beers have varying ABV percentages, which directly impact the number of units in a can.

In-Depth Review and Comparisons

To better understand the number of units in a 330 ml can of beer, let's consider a few examples:

  1. Standard Lager: A typical standard lager with an ABV of 4% will contain approximately 1.3 alcohol units in a 330 ml can. This is calculated by multiplying the ABV (4%) by the volume (330 ml) and dividing by 1,000.

  2. Craft Beer: Craft beers often have higher ABV percentages, ranging from 5% to 8% or even higher. For a craft beer with an ABV of 6%, a 330 ml can would contain around 2 alcohol units.

  3. Strong Beer: Strong beers, such as imperial stouts or barleywines, can have ABV percentages exceeding 10%. In a 330 ml can of a strong beer with an ABV of 10%, you would find approximately 3.3 alcohol units.

It's important to note that these calculations are approximate and can vary depending on the specific beer brand and brewing process. Always check the label or consult the brewery for accurate information on the ABV and units in a particular beer.


Knowing the number of units in a 330 ml can of beer allows individuals to make informed decisions about their alcohol consumption. It is essential to drink responsibly and be aware of the potential effects of alcohol on health and well-being. Understanding the units in a can of beer helps individuals track their alcohol intake and stay within recommended limits.

Q: How many units of alcohol are considered safe to consume? The recommended guidelines for safe alcohol consumption vary by country. In the UK, it is advised that both men and women should not regularly exceed 14 units per week, spread over several days, with at least a few alcohol-free days each week.

Q: Can the number of units in a beer can affect its taste? The number of units in a beer can does not directly impact its taste. The taste of a beer is influenced by factors such as the ingredients, brewing process, and beer style. However, higher ABV beers may have a stronger alcohol flavor.

Q: Are there any health risks associated with consuming too many units of alcohol? Excessive alcohol consumption can lead to various health risks, including liver damage, increased risk of certain cancers, cardiovascular problems, and impaired cognitive function. It is important to drink responsibly and within recommended limits.

Q: How can I calculate the number of units in a beer can with a different volume or ABV? To calculate the number of units in a beer can, multiply the ABV percentage by the volume in milliliters and divide by 1,000. This will give you the approximate number of alcohol units in the can.

Remember, responsible drinking involves understanding the units in your beverage, pacing yourself, and knowing your limits.
