How Many Standard Drinks in a Bottle of Wine? A Complete Guide

If you enjoy wine at home, during dinner or at social gatherings, understanding how many standard drinks are in a bottle of wine can help you make informed decisions about alcohol consumption.

The number of standard drinks in a bottle depends on its size and alcohol by volume (ABV). A standard bottle of wine typically contains 750ml, but the number of standard drinks can vary depending on whether the wine contains 11%, 12.5%, 13.5% or 15% alcohol.

In Australia, a standard drink contains 10 grams of pure alcohol. This measurement helps people understand how much alcohol they are consuming, regardless of the type of alcoholic beverage.

In this guide, we explain how to calculate standard drinks in a bottle of wine, compare different bottle sizes and understand alcohol content.

1. What Is a Standard Drink?

A standard drink is a measurement of the amount of pure alcohol in an alcoholic beverage. It does not refer to the size of the glass or bottle.

In Australia, one standard drink contains exactly 10 grams of pure alcohol.

Different alcoholic beverages contain different amounts of alcohol. For example, a glass of wine, a bottle of beer and a serving of spirits can all contain approximately one standard drink depending on their serving size and alcohol concentration.

Understanding standard drinks is useful because wine glasses and serving sizes can vary considerably.

2. How Many Standard Drinks Are in a Bottle of Wine?

A standard 750ml bottle of wine generally contains around 7 to 8 standard drinks, depending on its alcohol percentage.

Here is an approximate comparison:

Wine Alcohol Content	Standard Drinks in 750ml
11% ABV	6.5
12% ABV	7.1
12.5% ABV	7.4
13% ABV	7.7
13.5% ABV	8.0
14% ABV	8.3
15% ABV	8.9

These figures are rounded estimates based on the Australian standard drink definition.

For example, a 750ml bottle containing 13.5% alcohol has approximately 8 standard drinks.

This means that even a single bottle of wine can contain several standard drinks, making it important to check the alcohol percentage before pouring.

3. How to Calculate Standard Drinks in a Bottle of Wine

You can calculate the number of standard drinks in wine using a simple formula.

Australian standard drink formula:

\[ \text{Standard Drinks} = \frac{\text{Volume (ml)} \times \text{ABV (\%)} \times 0.789}{1000} \]

Here:

Volume refers to the total wine quantity in millilitres.
ABV refers to alcohol by volume.
0.789 represents the approximate density of pure alcohol in grams per millilitre.
1000 converts the alcohol quantity into 10-gram standard drinks.

Example calculation:

Suppose you have a 750ml bottle of wine containing 13% alcohol.

\[ \frac{750 \times 13 \times 0.789}{1000} = 7.69 \]

Therefore, the bottle contains approximately 7.7 Australian standard drinks.

You can use the same formula for red wine, white wine, rosé and sparkling wine.

4. How Many Standard Drinks Are in Different Wine Bottle Sizes?

Not all wine bottles have the same capacity. While 750ml is the most common size, wine is also available in smaller and larger bottles.

The following table shows approximate standard drinks for wine containing 13% alcohol.

Wine Bottle Size	Standard Drinks
187ml Mini Bottle	1.9
375ml Half Bottle	3.8
500ml Bottle	5.1
750ml Standard Bottle	7.7
1 Litre Bottle	10.2
1.5 Litre Magnum	15.4
3 Litre Bottle	30.7

These figures are calculated using the Australian standard drink formula. Actual quantities depend on the wine's alcohol percentage.

5. How Many Standard Drinks Are in a Glass of Wine?

The number of standard drinks in a glass depends on the serving size and alcohol concentration.

For example, a 150ml glass of wine can contain:

Wine Type	Alcohol Content	Standard Drinks
White Wine	11.5%	1.1
Red Wine	13.5%	1.6
Sparkling Wine	12%	1.1
Rosé Wine	12.5%	1.2

A 150ml restaurant serving is not necessarily one standard drink. A smaller 100ml serving of 13.5% red wine contains approximately one Australian standard drink.

This is why checking the serving size and alcohol percentage is important when calculating consumption.

6. Does Red Wine Have More Standard Drinks Than White Wine?

Red and white wines can contain different amounts of alcohol, which affects their standard drink count.

Red wines commonly have alcohol concentrations around 12.5% to 15%, while many white wines range between 11% and 13.5%.

For example:

A 750ml bottle of red wine at 13.5% contains approximately 8 standard drinks.
A 750ml bottle of white wine at 11.5% contains approximately 6.8 standard drinks.

However, these are examples rather than fixed rules. Some white wines have higher alcohol content than certain red wines.

The best way to calculate the standard drinks is to check the alcohol percentage printed on the bottle label.

7. How to Check Standard Drinks on a Wine Bottle Label

In Australia, packaged alcoholic beverages must display the approximate number of standard drinks they contain.

You can usually find this information on the back label near the alcohol percentage and product details.

Look for:

Alcohol by volume (ABV).
Bottle volume in millilitres.
Number of standard drinks per bottle.

For example, a 750ml bottle of wine containing 13.5% alcohol may display approximately 8 standard drinks.

Checking the label is generally the easiest way to determine the alcohol content without performing manual calculations.

8. Australian Alcohol Consumption Guidelines

Understanding standard drinks can help people make informed decisions about alcohol consumption.

According to Australia's National Health and Medical Research Council (NHMRC), healthy adults should consume no more than:

10 standard drinks per week.
4 standard drinks on any one day.

These are upper limits intended to reduce health risks, not recommended drinking targets. Drinking less reduces the risk of alcohol-related harm, and not drinking is the safest option in some circumstances.

Other practical considerations include:

Avoid drinking alcohol before driving.
Do not assume that one glass equals one standard drink.
Alternate alcoholic drinks with water or non-alcoholic beverages.
Avoid alcohol during pregnancy.
Do not provide alcohol to people under 18.
