Understanding the 'Standard Drink'
In Australia, a standard drink is defined as a beverage that contains 10 grams of pure alcohol. This definition is crucial for understanding and tracking alcohol intake. The standard drink measure helps consumers quantify their alcohol consumption accurately, regardless of the type or size of the drink, as the alcohol content itself can vary greatly. Knowing the standard drink count is essential for adhering to national health guidelines for low-risk drinking.
The Calculation for a VB Can
The number of standard drinks in a VB can is not a magical number, but a direct result of a specific calculation. To determine the number of standard drinks, you need two key pieces of information: the volume of the container and the alcohol by volume (ABV). The formula is:
- Standard Drinks = Volume of container (L) x ABV (%) x 0.789 (the specific gravity of ethanol)
Using the standard figures for a VB can (375ml volume, 4.9% ABV):
- 0.375 (L) x 4.9 (%) x 0.789 = 1.45
This calculation confirms the figures shown on product labels from major retailers. The slight differences in reported numbers (e.g., 1.4 vs 1.5) often come from rounding the final figure.
Factors Affecting Standard Drink Count
While the classic 375ml VB can has a consistent standard drink count, other variations can differ. It's important to always check the label of a specific product, as manufacturers are legally required to state the standard drink content.
Some common VB variations and other beers:
- VB Xtra: This version has a higher ABV, meaning the standard drink count per can or bottle will also be higher.
- VB Low Carb: As the name suggests, this variant is brewed differently and may have a different ABV and standard drink count than the original.
- Low-strength beer: Beers with a lower alcohol content, such as a 375ml can of mid-strength beer (3.5% ABV), contain fewer standard drinks (around 1.0).
Comparison Table: VB Can vs. Other Common Alcoholic Drinks
To put a can of VB into perspective, here's how it compares to other common alcoholic beverages. These figures are based on typical Australian serving sizes and ABV percentages.
| Drink Type | Standard Serving Size | Typical ABV | Standard Drink Equivalent | Notes |
|---|---|---|---|---|
| VB Can (Full Strength) | 375ml | 4.9% | ~1.45 | Based on the most common VB product. |
| Full-Strength Beer | 375ml stubby | 4.8% | ~1.4 | As per Australian health guidelines. |
| Mid-Strength Beer | 375ml can | 3.5% | ~1.0 | A significantly lower alcohol intake per can. |
| Glass of Red Wine | 150ml (restaurant pour) | 13.5% | ~1.6 | Can vary widely depending on the pour and wine. |
| Glass of White Wine | 150ml (restaurant pour) | 11.5% | ~1.4 | Similar to a can of VB in standard drinks. |
| Shot of Spirits | 30ml | 40% | ~1.0 | A small volume delivers one full standard drink. |
The Importance of Checking the Label
While guides can provide useful estimates, the most accurate source of information is always the product label itself. The standard drink information is legally required to be displayed on all packaged alcohol sold in Australia. This is particularly important with variations in beer strength and with different styles, like VB Xtra, which has a higher alcohol content. Relying on the label ensures you have the most up-to-date and accurate information for making informed decisions about your drinking.
Conclusion
To answer the question, a standard 375ml can of Victoria Bitter contains approximately 1.45 standard drinks, based on its 4.9% ABV. This figure is a precise measurement derived from the Australian definition of a standard drink (10g of alcohol). By understanding how this is calculated and checking product labels, consumers can confidently keep track of their alcohol intake in line with health recommendations. Always remember that responsible drinking involves more than just counting standard drinks, and individual tolerance can vary.

Responsible Drinking
Understanding the standard drink count is a fundamental part of practicing responsible drinking. It is a simple tool that provides a reliable metric for quantifying consumption, which is the first step towards moderation. For those seeking to manage or reduce their alcohol intake, being aware of the standard drink value of a single can is a valuable piece of information that can inform better choices and promote healthier drinking habits overall.
