How Many Servings in a Standard Wine Bottle

Let’s cut through the wine confusion—once and for all. As someone who’s poured, paired, and portioned wine for over 12 years (from Michelin-starred cellars to boutique retail), I can tell you: **a standard 750 mL wine bottle doesn’t magically contain ‘five glasses’—it depends on *how* you define a serving.**

The U.S. Dietary Guidelines define one standard drink as 14 g of pure alcohol—which translates to **5 fluid ounces (148 mL) of wine at ~12% ABV**. That’s the benchmark used by the CDC, NIH, and most health authorities.

So, simple math: 750 mL ÷ 148 mL ≈ **5.07 servings**. Round down to **5 full, consistent servings**—no guesswork, no ‘generous pours’ skewing your intake.

But here’s where reality bites: In restaurants, the average pour is 6–7 oz (177–207 mL). That shrinks your bottle to just **3–4 servings**, not 5. At home? Studies show self-pouring adds ~22% more volume per glass (Journal of Studies on Alcohol and Drugs, 2021).

To help you visualize:

Why does this matter? Because accurate portioning affects everything—from calorie tracking (a 5-oz glass of red wine averages 125 kcal) to responsible consumption and even inventory planning if you’re a retailer or event planner.

And if you're building habits around moderation, start with a proper pour tool—a 5-oz wine measure costs less than $10 and pays for itself in consistency.

Bottom line: It’s not about restriction—it’s about intention. Know your number. Respect your bottle.
