Let’s settle this once and for all: how many glasses of wine are actually in a standard 750ml bottle? As someone who’s poured, measured, and taught wine service to over 200 hospitality teams—and analyzed data from the Wine Institute, USDA, and NielsenIQ—I can tell you the answer isn’t just ‘five’. It depends on *how much you pour*, *what you’re serving*, and *why*.
A standard US restaurant pour is 5 oz (148 ml) — that gives you **exactly 5 servings** per 750ml bottle. But here’s where reality diverges from textbooks:
- Casual home pours often hit 6–7 oz (177–207 ml), dropping servings to **4–3.5** - Tasting flights use 2 oz (60 ml) portions → **up to 12 glasses** - Fortified wines (e.g., Port) are served at 3 oz (89 ml) → **~8 glasses**
Here’s how it breaks down quantitatively:
| Pour Size (oz) | Pour Size (ml) | Glasses per 750ml Bottle | Typical Use Case |
|---|---|---|---|
| 2.0 | 60 | 12.5 | Tasting events, sommelier exams |
| 3.0 | 89 | 8.4 | Fortified wines (Port, Sherry) |
| 5.0 | 148 | 5.1 | Standard restaurant service (US) |
| 6.5 | 192 | 3.9 | Average home pour (NielsenIQ 2023 survey) |
Why does this matter? Over-pouring by just 0.5 oz per glass adds up fast: across 100 bottles, that’s **~21 extra servings lost**—or $1,200+ in margin erosion for a midsize wine bar. Meanwhile, under-pouring frustrates guests and harms perceived value.
Pro tip: Use calibrated pour spouts or marked stemware. And if you're planning a party? Stick to the 5-oz standard—it balances generosity with sustainability. For deeper insights into portion control and wine inventory best practices, check out our full guide on wine serving fundamentals.
Bottom line: A bottle holds 750ml—but how many glasses it *delivers* is a choice, not a fact.
