750ml Wine Bottle: Total Grams of Alcohol at Every ABV
A 750ml bottle at 13% = 76.9g = 5.5 US standard drinks. Track how many glasses you pour and get your running BAC estimate.
Calculate Wine Bottle BAC →A full 750ml bottle of wine is the most common unit for home wine consumption worldwide. At 13% ABV, it contains 76.9g of ethanol — 5.5 US standard drinks. Sharing a bottle between two people means each person consumes 2.75 standard drinks. Drinking it alone means consuming more than 5 standard drinks in one sitting, which exceeds the NIAAA's definition of binge drinking for women (4+ drinks) and equals the binge threshold for men (5+ drinks).
How to Calculate Grams in a 750ml Bottle
Formula: 750 ml × ABV (decimal) × 0.789 = total grams in bottle. At 13% ABV: 750 × 0.13 × 0.789 = 76.9g of ethanol. This is 5.49 US standard drinks (14g each) or 9.6 UK units (8g each). The full table across all common wine ABVs:
Complete Grams Table: 750ml Bottle at Every Wine ABV
| ABV | Grams Ethanol | US Std Drinks | UK Units | BAC 70kg Male | BAC 60kg Female |
|---|---|---|---|---|---|
| 11% | 65.1g | 4.65 | 8.14 | 0.137% | 0.197% |
| 11.5% | 68.1g | 4.86 | 8.51 | 0.143% | 0.206% |
| 12% | 71.0g | 5.07 | 8.88 | 0.149% | 0.215% |
| 12.5% | 74.0g | 5.29 | 9.25 | 0.155% | 0.224% |
| 13% | 76.9g | 5.49 | 9.61 | 0.162% | 0.233% |
| 13.5% | 79.9g | 5.71 | 9.99 | 0.168% | 0.242% |
| 14% | 82.8g | 5.91 | 10.35 | 0.174% | 0.251% |
| 14.5% | 85.8g | 6.13 | 10.72 | 0.180% | 0.260% |
| 15% | 88.8g | 6.34 | 11.1 | 0.187% | 0.269% |
Grams = 750 × ABV × 0.789. These are total grams per bottle. US standard drink = 14g, UK unit = 8g. BAC figures are for consuming the entire bottle.

Track Your Wine Bottle BAC →How Many Standard Glasses in a 750ml Bottle?
| Glass Size | Glasses per 750ml Bottle | 13% ABV Grams per Glass | UK Units per Glass |
|---|---|---|---|
| 125ml (small) | 6 glasses | 12.8g | 1.60 |
| 150ml (restaurant standard) | 5 glasses | 15.4g | 1.92 |
| 175ml (UK medium pub) | 4.3 glasses | 18.0g | 2.25 |
| 250ml (UK large pub) | 3 glasses | 25.6g | 3.20 |
A standard restaurant pour is typically 150ml (5 glasses per bottle), while UK pub medium serves are 175ml (4.3 per bottle). If you consume half a bottle at 175ml pours, that is 2.1 glasses = 37.8g of ethanol at 13% ABV = 2.7 US standard drinks.
UK Units Per Bottle — The Weekly Guideline Context
The UK weekly guideline is 14 units maximum. A 750ml bottle at common ABVs:
- 11% ABV: 750 × 11 / 1000 = 8.25 units (59% of weekly guideline)
- 12.5% ABV: 750 × 12.5 / 1000 = 9.4 units (67% of weekly guideline)
- 13% ABV: 750 × 13 / 1000 = 9.75 units (70% of weekly guideline)
- 14.5% ABV: 750 × 14.5 / 1000 = 10.9 units (78% of weekly guideline)
A bottle of wine consumed on a Friday evening uses up 70–78% of the entire weekly recommended unit allowance. Drinking one bottle of wine on Friday and one on Saturday already exceeds the weekly guideline for most wine ABVs.
BAC Impact of Half and Full Bottle
| Amount | 13% ABV Grams | BAC 70kg Male (peak) | BAC 60kg Female (peak) |
|---|---|---|---|
| Half bottle (375ml) | 38.5g | 0.081% | 0.116% |
| Two-thirds (500ml) | 51.3g | 0.108% | 0.155% |
| Full bottle (750ml) | 76.9g | 0.162% | 0.233% |

Calculate Wine Bottle BAC →Frequently Asked Questions
How many calories in a 750ml bottle of wine?
Approximately 600–650 calories for a dry 13% red or white wine. At 7 kcal/g of alcohol, the ethanol alone accounts for 76.9g × 7 = 538 kcal. Add residual sugars (dry wine has ~2–4g/L, meaning ~1.5–3g per bottle) and you reach approximately 545–550 kcal total. Sweet wines can be 750+ kcal per bottle.
Is it safe to drink a full bottle of wine?
A full 750ml bottle of 13% wine (76.9g ethanol) consumed by a 60kg woman in one evening produces a peak BAC of over 0.20% — severe intoxication with serious health and safety risks. Spreading it over 4–5 hours with food significantly reduces peak BAC but still results in a BAC of approximately 0.08–0.10% by the end. The answer is that there is no "safe" amount, but the risks increase dramatically beyond 2–3 glasses.
Does the wine bottle size affect alcohol strength?
No — ABV is ABV regardless of bottle size. A magnum (1.5L) at 13% contains 153.8g of ethanol (double a 750ml bottle). A half bottle (375ml) at 13% contains 38.5g. Use the formula Volume (ml) × ABV × 0.789 for any bottle size. See our grams formula guide for the complete calculation method.
