175ml Wine Glass: Grams of Alcohol at Every ABV
A 175ml 13% wine has 18.0g — that's 1.3 US standard drinks, not 1. Enter your wine details for a precise BAC estimate.
Calculate Your Wine BAC →The 175ml wine glass is the standard medium serve in UK pubs and restaurants. It is the most common unit people refer to when they say "a glass of wine." But at 13% ABV — the average for popular red and white wines — this glass contains 18.0g of ethanol: more than one US standard drink and significantly more than the 14g most people assume.
How to Calculate Grams in a 175ml Wine Glass
Formula: 175 ml × ABV (decimal) × 0.789 = grams. For 13% wine: 175 × 0.13 × 0.789 = 18.0g. For the lightest wines at 11%: 175 × 0.11 × 0.789 = 15.2g. For 15% (a heavy Zinfandel or Shiraz): 175 × 0.15 × 0.789 = 20.7g. The full table below covers every common wine ABV.

Grams = 175 × ABV × 0.789. US standard drink = 14g, UK unit = 8g. BAC estimates at peak, empty stomach, Widmark formula.

In the UK, one unit = 10ml (8g) of pure ethanol. A 175ml glass at 13% ABV = 18.0g / 8g = 2.25 UK units. UK chief medical officers recommend no more than 14 units per week. That means just 6 glasses of 13% wine per week (13.5 units) approaches the weekly guideline.
A common misconception is that one glass equals one unit. This was true when wine was 8–9% ABV in the 1990s. Modern wines average 12–14% ABV, making the "one glass = one unit" rule dangerously outdated. A 175ml glass of today's wine is closer to 2–2.5 units.
Comparing Wine Glass Sizes (125ml vs 175ml vs 250ml)
| Glass Size | 13% ABV Grams | US Std Drinks | UK Units |
|---|---|---|---|
| 125ml (small) | 12.8g | 0.91 | 1.60 |
| 175ml (medium) | 18.0g | 1.28 | 2.25 |
| 250ml (large) | 25.6g | 1.83 | 3.20 |

How a 175ml Glass Affects BAC
For a 60kg woman (r=0.55), one 175ml glass of 13% wine produces a peak BAC of approximately 0.055% — already in the range of measurable impairment and approaching the European driving limit of 0.05%. Two glasses brings her to 0.109% — over the UK/US 0.08% limit. Food can reduce these numbers by 20–40%.
For a 70kg man (r=0.68), one 175ml glass at 13% produces approximately 0.038% peak BAC. Two glasses: 0.076% — just under the US limit but over the EU 0.05% limit. Three glasses: 0.114% — clearly over all limits.

Why does my "one glass of wine" count as more than one drink?
Because wine ABV has risen dramatically over the past 30 years, driven by consumer preference for richer, fuller-bodied styles, global warming, and winemaking practices. A 175ml glass at 13% ABV contains 18g of ethanol — 28% more than a US standard drink (14g) and 125% of a UK unit (8g). The "one drink" perception is based on outdated wine strengths.
How many 175ml glasses in a 750ml bottle?
750ml / 175ml = 4.3 glasses. A full bottle pours approximately 4 medium glasses, not 5 as often assumed (which would be 150ml per glass). At 13% ABV, a 750ml bottle contains 76.9g of ethanol = 5.5 US standard drinks or 9.6 UK units. See 750ml wine bottle grams table.
What is the lightest commercially available wine at 175ml?
Some German Rieslings and Italian Proseccos are as low as 8–9% ABV. A 175ml glass at 9% ABV would contain just 12.4g — under a US standard drink. However, most table wines and the vast majority of wine sold in restaurants and supermarkets are 12–14% ABV.
