How Many Standard Drinks in a Bottle of Wine?

Understanding how many standard drinks are in a bottle of wine is essential for responsible enjoyment, whether you’re savouring a Barossa Shiraz, a Clare Valley Riesling, or a Margaret River Chardonnay. In Australia, one standard drink contains exactly 10 grams of pure alcohol. This uniform measure allows you to compare different wines and track your intake against national health guidelines.

The Standard Drink Formula

To calculate standard drinks in any wine bottle, use the formula:

Standard Drinks = (Volume in mL × Alcohol % × 0.789) ÷ 10

– Volume in mL is your bottle size (typically 750 mL).
– Alcohol % is the alcohol-by-volume (ABV) stamped on the label.
– 0.789 is the density of ethanol (g/mL).

For a 750 mL bottle at 13% ABV:
(750 × 13% × 0.789) ÷ 10 ≈ 7.7 standard drinks.

Standard Drinks by Wine Style

Australian wines vary widely in strength. Here’s a breakdown of common styles:

• Light-bodied whites (e.g., Riesling, Moscato): 8–10% ABV = 6.3–7.4 standard drinks per bottle

• Medium whites (e.g., Sauvignon Blanc, Pinot Gris): 11–13% ABV = 8.6–10 standard drinks

• Full-bodied whites (e.g., Chardonnay): 13–14.5% ABV = 10–11.5 standard drinks

• Light reds (e.g., Pinot Noir): 12–13.5% ABV = 7.1–8.3 standard drinks

• Medium reds (e.g., Grenache, Merlot): 13–14.5% ABV = 8.3–10.4 standard drinks

• Full-bodied reds (e.g., Shiraz, Cabernet): 14–15.5% ABV = 10.4–11.6 standard drinks

What This Means for Your Health

The Australian Guidelines recommend no more than 10 standard drinks per week, and no more than 4 per day, to reduce long-term health risks. A single 750 mL bottle of 13% wine (7.7 standard drinks) fits within weekly limits but exceeds the daily maximum if consumed by one person in a single sitting.

Sharing a bottle between two people yields about 3.85 standard drinks each—comfortably under the four-drink daily limit. Even splitting among three still keeps each serve around 2.6 standard drinks.

Pour Sizes vs. Standard Drinks

A 150 mL glass of 13% wine contains 1.6 standard drinks, not one. Restaurant pours (120 mL) are about 1.3 standard drinks. Home pours often exceed 150 mL, so measuring is key to maintaining accurate intake.

Tips for Australian Wine Lovers

1. Check the label for ABV and standard drink count.

2. Measure your pour with a jigger to stay within guidelines.

3. Alternate with water to pace consumption.

4. Track your intake with a diary or smartphone app.

5. Mind the bottle size—magnums (1.5 L) hold double the standard drinks of a 750 mL bottle.

By knowing exactly how many standard drinks are in a bottle of wine, you can enjoy Australia’s finest vintages responsibly—whether you’re savouring a crisp Clare Valley Riesling or indulging in a rich Barossa Shiraz—ensuring both pleasure and safety.
