how many standard drinks in a bottle of wine
A standard 750ml bottle of wine typically contains about 5 standard drinks , assuming a typical alcohol by volume (ABV) of around 12%.
This figure comes from health authorities like the NIAAA, where one standard drink equals roughly 14 grams of pure alcohol—equivalent to 5 ounces (148ml) of table wine.
Calculation Breakdown
The math is straightforward: A 750ml bottle at 12% ABV holds 90ml of pure alcohol (750 × 0.12). Divide by 14 grams per standard drink (about 17.7ml of pure ethanol), and you get approximately 5 servings.
Variations occur based on ABV and bottle size, as shown here:
Wine Type| Typical ABV| Standard Drinks (750ml)
---|---|---
Light whites (e.g., Riesling)| 9–11%| 4–4.5 1
Standard reds/whites (e.g., Pinot Noir)| 12–13.5%| 5–5.5 15
Bold reds (e.g., Zinfandel)| 14–15%| 5.8–6 1
Fortified (e.g., Port)| 17–20%| 7–8+ 1
Why It Matters
Pouring by visual "glass" often leads to overserving—many wine glasses hold 6–8 ounces, pushing a single pour toward 1.5+ drinks. Guidelines recommend no more than 1–2 drinks daily for moderation.
TL;DR: Expect 5 standard drinks in most 750ml bottles, but always check the label for ABV.
